 National Indian Gaming Commission 25 CFR Part 547
RIN 3141-AA29
 AGENCY: National Indian Gaming Commission (NIGC or “Commission”).
 ACTION: Proposed rule.
 SUMMARY: The proposed rule would add a new part to the Commission's regulations establishing technical standards for Class II games—bingo, lotto, other games similar to bingo, pull tabs, or “instant bingo”—that are played primarily through “electronic, computer, or other technologic aids.” The proposed rule would also establish a process for assuring the integrity of such games and aids before their placement in a Class II tribal gaming operation. No such standards currently exist. The Commission proposes this action in order to assist tribal gaming regulatory authorities and operators in ensuring the integrity and security of Class II games and gaming revenue.

SUPPLEMENTARY INFORMATION: Background The Indian Gaming Regulatory Act, 25 U.S.C. 2701-21 (“IGRA”), enacted by the Congress in 1988, establishes the National Indian Gaming Commission (“NIGC” or “Commission”) and sets out a comprehensive framework for the regulation of gaming on Indian lands. The Act establishes three classes of Indian gaming. “Class I gaming” means social games played solely for prizes of minimal value or traditional forms of Indian gaming played in connection with tribal ceremonies or celebrations.25 U.S.C. 2703(6). Indian tribes regulate Class I gaming exclusively.
                    “Class II gaming” means the game of chance commonly known as bingo, whether or not electronic, computer, or other technologic aids are used in connection therewith, including, if played in the same location, pull-tabs, lotto, punch boards, tip jars, instant bingo, and other games similar to bingo, as well as various non-house banked card games.25 U.S.C. 2703(7)(A). Specifically excluded from Class II gaming are banking card games such as blackjack, electronic or electromechanical facsimiles of any game of chance, and slot machines of any kind. 25 U.S.C. 2703(7)(B). Indian tribes and the NIGC share regulatory authority over Class II gaming. Indian tribes can engage in Class II gaming without any state involvement.
                    “Class III gaming” includes all forms of gaming that are not Class I gaming or Class II gaming.25 U.S.C. 2703(8). Class III gaming thus includes all other games of chance, including lotteries and most forms of casino gaming, such as slot machines, roulette, and banking card games like blackjack. Class III gaming may be conducted lawfully only if the tribe and the state in which the tribe is located enter into a tribal-state compact for such gaming. Alternatively, a tribe may operate Class III gaming under gaming procedures issued by the Secretary of the Interior. Because of the compact requirement, states, Indian tribes, and the NIGC possess regulatory authority over Class III gaming. In addition, the United States Department of Justice and United States Attorneys possess exclusive criminal, and certain civil, jurisdiction over Class III gaming on Indian lands. The Commission has determined that it is in the best interests of Indian gaming to adopt technical standards that govern the implementation of electronic, computer, and other technologic aids used in the play of Class II games because no such standards currently exist. The technical standards seek to provide a means for tribal gaming regulatory authorities and tribal operators to ensure that the integrity of Class II games played with the use of electronic, computer, or other technologic aids is maintained; that the games and aids are secure; and that the games and aids are fully auditable, i.e. that they provide a means for the gaming authority and gaming operation to account for all gaming revenue. Development of the Proposed Rule Through Consultation With Indian Tribes In recognition of tribal sovereignty and the fundamental importance of standards to the operation and regulation of gaming on Indian lands under IGRA, the Commission developed a policy and process for consultation with Indian tribes that would provide opportunity for early and meaningful tribal input regarding formulation of these proposed regulations. In particular, while initially advising tribes of the Commission's intention to develop standards, the Commission also actively consulted with tribes regarding formulation of the Commission's first-ever official Government-to-Government Tribal Consultation Policy. After several months of consultation with tribes, the Commission's official Tribal Consultation Policy was adopted and published in the 
                        **Federal Register**
                         on March 31, 2004 (69 FR 16973). The Commission purposely established this policy in order to have consultation policy guidelines in place for meaningful pre-rulemaking tribal consultation on these standards and other planned Commission rulemaking initiatives. The Commission's official Tribal Consultation Policy expressly calls for the Commission, to the extent practicable and permitted by law, to engage in regular, timely, and meaningful government-to-government consultation with Indian Tribes when formulating proposed new or revised administrative regulations that may substantially affect the operation or regulation of gaming on Indian lands. To fulfill this policy commitment, the Commission devised a three-part plan to afford tribes a reasonable and practicable opportunity to consult with the Commission and to provide early input in formulation of regulations, before they were published as proposed new rules in the 
                        **Federal Register**
                         and the actual rule-making process began. First, the Commission endeavored to consult in person at least twice with each gaming tribe between May 2003 and March 2006 regarding development of these, and other, proposed regulations. During this time period, the Commission sent out over 500 separate invitations to individual tribes to consult with the Commission and provide input. Many tribes accepted and participated in separate government-to-government consultation meetings with the Commission regarding the proposed regulations and other matters. While some tribes declined the Commission's invitations, between May 2003 and 
                        ( print page 46337)
                        March 2006 the Commission conducted over 300 separate government-to-government consultation meetings with individual tribes and their leaders or representatives. Second, the Commission established a joint Federal-Tribal Advisory Committee on March 31, 2004, composed of both Commission and tribal representatives to assist the Commission in formulating these regulations. In January 2004, the Commission requested all gaming tribes across the country to nominate tribal representatives to serve on this Advisory Committee. From the tribal nominations received, the Commission selected the following seven tribal representatives on March 31, 2004: Norm Des Rosiers, Gaming Commissioner, Viejas Band of Kumeyaay Indians; Joseph Carlini, Gaming Commission Executive Director, Agua Caliente Band of Cahuilla Indians; Kenneth Ermatinger, Gaming Commission Executive Director, Sault Ste. Marie Tribe of Chippewa Indians of Michigan; Jamie Hummingbird, Gaming Commission Director, Cherokee Nation, Oklahoma; Mark Garrow, Gaming Commission Inspections Manager, St. Regis Mohawk Tribe; Melvin Daniels, General Manager, Muckleshoot Indian Bingo, Muckleshoot Indian Tribe; Charles Lombardo, Senior Vice-President for Gaming Operations, Seminole Tribe of Florida. To date, the Advisory Committee has held six (6) meetings: May 13, 2004 in Washington, DC; August 2-3, 2004, Washington, DC; September 13-14, 2004, Cherokee, North Carolina; December 1-3, 2004, Oklahoma City, Oklahoma; January 12-13, 2005, Palm Springs, California; and March 11, 2005, Chicago, Illinois. During these committee meetings, all of which were open to the public, the committee discussed the various characteristics of Class II and Class III games of chance, their play, and related gaming technology and methods. In addition, the committee discussed, reviewed, critiqued and commented on 2 different, successive preliminary working drafts of the proposed Class II technical standards prepared by the Commission representatives on the Committee. The seven tribal committee representatives provided early tribal input and valuable insight, advice, and assistance to the Commission in developing each of the respective working drafts, as well as the current proposed regulations. The Commission's establishment of the joint Federal-Tribal advisory committee was the subject of a legal challenge while the Commission was preparing the proposed rule for publication. On March 10, 2005, nearly one year after the Commission established the committee, the Confederated Salish and Kootenai Tribes of the Flathead Nation and the Santa Rosa Rancheria Indian Community filed suit against the Commission alleging, among other things, that several of the committee members were not eligible to participate on the committee. Following a hearing in Federal court, at which the request for temporary restraining order was denied, the Commission determined that it should proceed to publish the proposed rule for comment while the legal standing of the committee was further litigated. The Commission also sought clarification from those tribes nominating the committee members concerning the member's role as an official representative of the tribe. As a result of this clarification, and, out of an abundance of caution, the Commission regretfully requested that two members of the Committee step down. The third component of the Commission's effort to consult with tribes during the pre-rulemaking formulation phase of these proposed regulations was to make the various preliminary working drafts of the proposed regulations available to all tribes and their leaders for review and comment, independent of the joint federal-tribal Advisory Committee. In particular, while these proposed regulations were being formulated, the first and second preliminary working drafts were mailed to each tribe and its leaders, inviting written comment. The drafts were also posted on the Commission's website for review and comment by all. Many tribes and members of the public submitted written comments on these respective working drafts. The tribal comments were shared with the members of the Advisory Committee for their review and carefully considered by the Commission in formulating these proposed regulations. In addition, the Gaming Standards Association, a casino-industry group comprised of game manufacturers and operators, and the National Indian Gaming Association, the largest Indian gaming trade group, assembled a meeting on December 16, 2004, in Las Vegas, Nevada, so that interested members of both organizations could review the technical standards and provide suggestions to the Commission. The Commission was invited, and it sent a staff member to listen to the discussion and to answer questions, if necessary. Beyond all of this, the Commission attended and addressed several different assemblies of tribal leaders and tribal gaming operators and regulators at meetings and conferences organized by state and regional tribal gaming associations, the National Indian Gaming Association, and the National Congress of American Indians between January 2003 and March 2005. At these meetings and conferences, the Commission advised tribal leaders of its intention and plan to develop these regulations and provided periodic updates regarding the progress and status of the regulations development. The Commission also made itself available at these meetings to answer any questions from tribal leaders regarding the proposed regulations or their formulation. Through each of these various means, the Commission actively endeavored to provide all tribes with a reasonable and practical opportunity over the past 26 months to meet and consult with the Commission on a government-to-government basis and provide early and meaningful tribal input regarding the formulation and implementation of these proposed regulations. Purpose and Scope The proposed Part 547 applies to Class II games played primarily through electronic, computer, or other technologic aids, or modifications of such games and aids. It does not apply to live session bingo. Class II games played through such technologic aids are widely used in Indian gaming operations, yet no uniform standards exist to govern their implementation. The proposed rule seeks to remedy that absence and establish technical standards for such games and aids. Again, the technical standards seek to provide a means for tribal gaming regulatory authorities and tribal operators to ensure that the integrity of Class II games played with the use of electronic, computer, or other technologic aids, is maintained; that the games and aids are secure; and that the games and aids are fully auditable. In so doing, the technical standards are modeled, when appropriate, on similar standards from experienced gaming jurisdictions not only in North America but around the world. The requirements for game accounting meters, for example, are modeled on Nevada's requirements. There are, however, unique aspects of Class II gaming for which few models now exist, and none existed at the time the Commission began this project. Bingo, as IGRA defines it, is a multiple-player game in which players compete against one another to be the first to cover a predetermined pattern of 
                        ( print page 46338)
                        numbers or other designations. In order to meet IGRA's statutory requirements, electronic bingo implementations must allow multiple players in different locations, whether in one facility or in more than one, to play a common game. Manufacturers, therefore, have implemented bingo on client-server architectures. A common arrangement, but by no means the only one possible, is to have client machines on the casino floor as electronic player stations. These display bingo cards, allow the players to cover numbers when drawn, and pay any prizes won. The server, usually located off the floor, draws random numbers and passes them, along data communications lines, to the client machines for game play. Such client-server arrangements are not common in other gaming jurisdictions, and they produce regulatory challenges with which most other gaming jurisdictions have not fully grappled. Chief among these challenges is securing games from unauthorized changes or tampering. In a stand-alone Class III slot machine, for example, the game software is typically located within the game cabinet itself, and there are many, well-established technical means for securing the software. In client-server implementations, by contrast, game software may be downloaded from the server to clients, or game software may exist simultaneously on clients and servers, with the clients acting as terminals receiving game information transmitted across data communication lines from the server. In either case, the well-established means of securing Class III game software may not be adequate. The proposed rule therefore implements minimum standards for mechanisms that can be used to verify the authenticity of game software, whether located on servers or clients or both, as well as minimum standards for when verification must occur and when, and by whom, games may be downloaded or changed. The proposed rule also provides general, minimum technical standards for servers, for clients, and standards common to both clients and servers, and it provides minimum standards for software storage media, money and credit handling, and data communications, all of which may require different treatment when using clients and servers rather than stand-alone games. That said, the proposed rule provides only minimum standards. Tribes and tribal gaming regulatory authorities may add any additional requirements, or more stringent requirements, needed to suit their particular circumstances. In addition, the proposed rule makes no attempt to foreclose the implementation of new technologies. In order to ensure compliance with the technical standards, the proposed rule borrows again from the established practices of tribal, state, and provincial gaming jurisdictions across North America. The proposed rule establishes, as a necessary prerequisite to a game and aid being offered to the public for play in a Class II gaming operation, a process of game submission by the manufacturer; review and analysis by a qualified, independent testing laboratory; and approval by the tribal gaming regulatory authority. Under the proposed rule, a tribe's gaming regulatory authority will require all Class II games and aids, or modifications of such games and aids, to be submitted by the manufacturer to a testing laboratory for review and analysis. That submission includes a working prototype of the game and aid, all pertinent software, and the complete documentation and description of all functions and components. In turn, the laboratory will certify that the game or aids do or do not meet the requirements of the proposed rule, as well as any additional requirements adopted by the tribe's gaming regulatory authority. The laboratory will provide a written certification and report of its analysis and conclusions to the tribal gaming regulatory authority for its approval or disapproval of the game or aid. The tribal gaming regulatory authority will retain the certification and report as long as the game remains available to the public for play on the casino floor. This will allow the commission to perform its regulatory oversight role. Finally, the Commission is cognizant of existing standards under the Minimum Internal Control Standards (MICS), 25 CFR part 542, some of which address equipment or technical issues. The proposed rule and the MICS therefore have small areas of overlap. The Commission does not intend by the proposed rule to alter or repeal part 542, and relevant parts of the proposed rule so state. Regulatory Matters Regulatory Flexibility Act This proposed rule will not have a significant economic effect on a substantial number of small entities as defined under the Regulatory Flexibility Act, 5 U.S.C. 601 
                        *et seq.*
                         Indian tribes are not considered to be small entities for the purposes of the Regulatory Flexibility Act. Small Business Regulatory Enforcement Fairness Act This proposed rule is not a major rule under 5 U.S.C. 804(2), the Small Business Regulatory Enforcement Fairness Act. This rule does not have an annual effect on the economy of $100 million or more. This rule will not cause a major increase in costs or prices for consumers, individual industries, Federal, state or local government agencies or geographic regions and does not have a significant adverse effect on competition, employment, investment, productivity, innovation, or the ability of U.S.-based enterprises to compete with foreign-based enterprises. The Commission believes that the requirement for examination and testing by an independent testing lab will add only limited additional expense to Indian casinos operating Class II games and aids. The Commission has been informed that operations already do this as a matter of course. Likewise, the Commission does not anticipate significant additional costs for redesign and repurchase of Class II games and aids. Many manufacturers who sell Class II games and equipment are already building to similar standards for the machines they sell in Class III and non-Indian casino markets. Moreover, feedback from manufacturers to date indicates industry support for these standards. Unfunded Mandates Reform Act For these reasons as well, the Commission has determined that this proposed rule does not impose an unfunded mandate on state, local, or tribal governments or on the private sector of more than $100 million per year. Thus, it is not a “significant regulatory action” under the Unfunded Mandates Reform Act, 2 U.S.C. 1501 
                        *et seq.*
                         The Commission has determined that this proposed rule may have a unique effect on tribal governments, as this rule applies to tribal governments, whenever they undertake the ownership, operation, regulation, or licensing of gaming facilities on Indian lands as defined by the Indian Gaming Regulatory Act. Thus, in accordance with section 203 of the Unfunded Mandates Reform Act, the Commission implemented a small government agency plan that provides tribal governments with adequate notice, opportunity for meaningful consultation, and information, advice, and education on compliance. Again, the Commission's plan included the formation of a tribal advisory committee and request for input from tribal leaders through 
                        ( print page 46339)
                        government-to-government consultations and through written comments to draft regulations that are provided to the tribes. Section 204(b) of the Unfunded Mandates Reform Act exempts from the Federal Advisory Committee Act (5 U.S.C. App.) meetings with tribal elected officials (or their designees) for the purpose of exchanging views, information, and advice concerning the implementation of intergovernmental responsibilities or administration. In selecting Committee members, consideration was placed on the applicant's experience in this area, as well as the size of the tribe the nominee represented, geographic location of the gaming operation, and the size and type of gaming conducted. The Commission attempted to assemble a committee that incorporated diversity and was representative of tribal gaming interests. The Commission will meet with the Advisory Committee to discuss the public comments that are received as a result of the publication of this proposed rule and make recommendations regarding the final rule. The Commission also plans to continue its policy of providing technical assistance, through its field offices, to tribes to assist in complying with issues raised by the proposed rule. Takings In accordance with Executive Order 12630, the Commission has determined that this proposed rule does not have significant takings implications. A takings implication assessment is not required. Civil Justice Reform In accordance with Executive Order 12988, the Office of General Counsel has determined that the proposed rule does not unduly burden the judicial system and meets the requirements of sections 3(a) and 3(b)(2) of the Order. Paperwork Reduction Act This proposed rule requires information collection under the Paperwork Reduction Act of 1995, 44 U.S.C. 3501, 
                        *et seq.*, and is subject to review by the Office of Management and Budget. The title, description, and respondent categories are discussed below, together with an estimate of the annual information collection burden. With respect to the following collection of information, the Commission invites comments on: (1) Whether the proposed collection of information is necessary for proper performance of its functions, including whether the information would have practical utility; (2) the accuracy of the Commission's estimate of the burden of the proposed collection of information, including the validity of the methodology and assumptions used; (3) ways to enhance the quality, utility, and clarity of the information to be collected; and (4) ways to minimize the burden of the collection of information on respondents, including the use of automated collection techniques, when appropriate, and other forms of information technology. *Title:*
                         Process for Certification of Electronic, Computer, or other Technologic Aids used in the play of Class II games, proposed 25 CFR 547.4. *Summary of information and description of need:*
                         This provision in the proposed rule establishes a process for assuring that electronic, computer, or other technologic aids used with the play of Class II games have been reviewed and evaluated by a qualified, independent testing laboratory prior to their approval by a tribal gaming regulatory authority and their placement on the floor in a Class II tribal gaming operation. The process helps to ensure the proper functioning of the equipment and the integrity, fairness, and auditability of games played. The process requires a tribe's gaming regulatory authority to require that all Class II games played primarily through electronic, computer, or other technologic aids, or modifications of such games and aids, be submitted by the manufacturer to a qualified, independent testing laboratory for review and analysis. That submission includes a working prototype of the game and aid, all pertinent software, and complete documentation and descriptions of all functions and components. In turn, the laboratory will certify that the game or aids do or do not meet the requirements of the proposed rule and any additional requirements adopted by the tribe's gaming regulatory authority. The laboratory will provide a written certification and report of its analysis and conclusions to the tribal gaming regulatory authority for its approval or disapproval of the game or aid. This process is necessary to ensure the fairness and integrity of Class II gaming. Technical standards such as those in the proposed rule are a fundamental part of Class III gaming and of non-Indian casino gaming throughout North America. No uniform standards exist for Class II gaming, however. The implementation of such standards will assist tribal gaming regulators in ensuring that games are implemented fairly, that all technologic aids are secure and function properly, and that the games and aids allow the tribe and the operator to properly account for gaming revenue. *Respondents:*
                         The respondents are independent testing laboratories and developers and manufacturers of Class II games and technologic aids. The Commission estimates that there are 20 such manufacturers and 5 such laboratories. The frequency of responses to the information collection requirement will vary. During the first 6 to 12 months after adoption of the proposed rule, all existing games or aids in Class II operations that fall within the rule must be submitted and reviewed if they are to continue in Class II operations. Following that period, the frequency of responses will be a function of the Class II market and the need or desire for new games and aids. Thus, the Commission estimates that the frequency of responses will range over an initial period of frequent submissions, settling down into infrequent and occasional submissions during periods when there are a few games, aids, or modifications brought to market, punctuated by fairly steady periods of submissions when new games and aids are introduced. The Commission estimates that submission will number approximately 150 during the first year after adoption and approximately 75 per year thereafter. *Information Collection Burden:*
                         The preparation and submission of documentation supporting submissions by developers and manufacturers (as opposed to the game or aid hardware and software per se) is an information collection burden under the Paperwork Reduction Act, as is the preparation of certifications and reports of analyses by the laboratories. The amount of documentation or size of a laboratory certification and report is a function of the complexity of the game, equipment, or software submitted for review. Minor modifications of software or hardware that a manufacturer has already submitted and that a laboratory has previously examined is a matter of little time both for manufacturer and laboratory, while the submission and review of an entirely new game platform is time consuming. The practice of submission and review set out in the proposed rule, however, is not new. It is already part of the regulatory requirements in tribal, state, and provincial gaming jurisdictions throughout North America and the world. Manufacturers already have significant compliance personnel and infrastructure in place, and the very existence of private, independent laboratories is due to these requirements. 
                        ( print page 46340) Accordingly, the Commission estimates that gathering and preparing documentation for a single submission requires, on average, eight hours of an employee's time for a manufacturer. The Commission also estimates that following examination and analysis, writing a report and certification requires, on average, 12.5 hours of an employee's time for a laboratory. The Commission estimates that the information collection requirements in the proposed rule will be a 1200-hour burden on manufacturers during the first year after adoption and a 600-hour burden thereafter. The Commission estimates that the information collection requirements in the proposed rule will be a 1875-hour burden on laboratories during the first year after adoption and a 940-hour burden thereafter.

 § 547.17
  This section provides minimum standards for the Formal Application Configuration (FAC) document and verification tool required for submission of equipment, software, or modifications of equipment or software used with the play of Class II games to a test laboratory and to a tribal gaming regulatory authority pursuant to § 547.4(b)(2)-(4); for verification of game software on clients and servers pursuant to 
                                ( print page 46355)
                                § 547.18(a)(6) and § 547.19(b)(3); and EPROM control standards pursuant to § 542.13(g) of this chapter. (a) 
                                *Contents of the FAC document.*
                                 (1) The Formal Application Configuration (FAC) document shall include a detailed file and directory listing of all of the following software, as applicable: (i) .EXE, .DLL, .JAR and other executable files and their necessary components; (ii) Scripts; (iii) Stored database procedures; (iv) Fixed parameter files affecting any game outcome, game mathematics, game denomination, or available prizes (excluding parameters expected to periodically change); (v) Batch files; (vi) Fixed data and graphic information; (vii) Reports used to verify the correct working of the game software; (viii) Compressed files expanded to be any of these; and (ix) Any other software required by the tribal gaming regulatory authority. (2) For all software listed in paragraph (a)(1) of this section, the FAC document shall include a signature or hash value calculated using an algorithm that meets the requirements of § 547.23(c). If the algorithm uses signature seeds (algorithm coefficients), each FAC record shall contain the signature result for each seed maintained by the verifying tool. Alternatively, the FAC document may contain a list of controlled directories and a signature value for each such directory as calculated by the verification tool. (3) The FAC document shall identify all files that, if discovered to be altered or missing by the verification tool, require a shutdown of the server or client. (4) The FAC document shall be labeled with a unique identifier indicating the software with which it is associated. (5) The FAC document shall describe in detail the verification tool associated with it. (b) 
                                *FAC verification tool, generally.*
                                 No particular implementation is required, unless required by the tribal gaming regulatory authority. Verification tools may include third-party program storage (ROM) verification devices; commonly available third-party signature algorithms; hashing formulas such as SHA-1, provided that they use a seed of not less than four digits as a part of the calculation; or any other implementation that meets the requirements of this section and contains or is able to access the listing of game software files, directories, and signatures presented in the FAC document for the purposes of comparison and verification. (c) 
                                *FAC verification tool, general methodology.*
                                 The FAC verification tool shall be capable of: (1) Searching through the directory structure of the game program storage media; (2) Performing and reporting signature checks on files individually or on entire directories in the game software using an algorithm that: (i) Meets the hashing requirements specified § 547.23(c); (ii) Processes individual software components, fixed data components, and entire software suites; and (iii) Is capable of using a seeding methodology that will allow for a random or manually selected seed as part of the signature calculation—if the algorithm requires signature seeds, these shall be manually entered or selected from an external device or randomly selected from a pool of seeds and checksums; (3) Comparing files and directories in the game software, or their signatures, with the files and directories, or their signatures, in the FAC listing provided in the FAC document. (4) Reporting file names, time and date stamps, and size for all files and directories; (5) Reporting the following error conditions, which shall be logged and reported to the tribal gaming regulatory authority: (i) Mismatching or modified files and directories; (ii) Files or directories present in the game software but not in the FAC listing; and (iii) Files or directories present in the FAC listing but not the game software; (6) And any other requirements specified by the tribal gaming regulatory authority. (d) 
                                *FAC verification tool, specific requirements.*
                                 Notwithstanding the requirements of paragraphs (b) through (c) of this section, the implementation of the verification tool shall meet the following requirements: (1) The verification tool shall not be spoofed by a program or thread operating on the hardware and software under test; and (2) The FAC listing in, or available to, the verification tool shall be encrypted using a methodology that satisfies the requirements of § 547.23(b). (e) 
                                *FAC verification tool, external locations.*
                                 (1) The verification tool may reside on a medium external to the Class II client-server implementation. (2) [Reserved] (f) 
                                *FAC verification tool located on a server.*
                                 The verification tool may reside on a server. In such a case: (1) The server shall contain the FAC listings for each client. (2) The server shall initiate verification of the client by passing the FAC without signatures to the client. (3) The client shall pass the signature results to the server for verification. (4) Errors and warnings identified during the test shall be logged on the server or an external monitoring system and reported to the screen of the server. Failure or error on critical software files does not require that the device be immediately disabled unless the check failure occurs immediately after the software download verification required by § 547.18(a)(6). (g) 
                                *FAC self-verification.*
                                 A server or client may self verify, i.e. use a verification located on that server or client for the purpose of checking the software it contains, provided that: (1) One or more base devices at the beginning of a chain of security verify peer devices, and the base device(s) are themselves verified by some external means. An example of such a technique is when the Boot ROM for a PC is modified to check running versions of software before enabling this software to run; the Boot ROM could be in a removable EPROM which could be verified by an external EPROM verifier. (2) The verification tool is itself verified by the gaming laboratory and the tribal gaming regulatory authority as secure from tampering or compromise. (3) Self-verification is implemented only in addition to, not in lieu of, other verification tool options allowed by paragraphs (e) and (f) of this section. (h) 
                                *Running the FAC verification tool.*
                                 The FAC verification tool shall be run to verify the authenticity of Class II game software and paytables: (1) Following the addition, removal, or change of game software or paytables pursuant to § 547.19; (2) Following the download of game software or paytables pursuant to § 547.18; (3) Pursuant to EPROM control standards adopted by the tribal gaming regulatory authority in accordance with § 542.13(g) of this chapter; (4) After recovery from any power failure or upon power up; and (5) At any other time required by the tribal gaming regulatory authority. (i) 
                                *Verification of non-interrogatable devices.*
                                 Program devices that cannot be interrogated, such as Smart cards, may be used provided they are able to be verified by the following FAC methodology: (1) A challenge is sent by the peer device, such as a hashing seed, to which 
                                ( print page 46356)
                                the device must respond with a checksum of its entire program space using the challenge value. (2) The challenge mechanism and means of loading the software into the device is verified by the independent testing laboratory and approved by the tribal gaming regulatory authority.
 § 547.18
  This section provides standards for the downloading of Class II games or paytables to clients or servers on the casino floor for patron play. (a) 
                                *Downloads.*

Logging of the unique FAC identifier will satisfy this requirement; (v) The user who initiated the download; (vi) The outcome of the FAC verification following the download (success or failure). (11) Download logs shall be retained for a period of one year from the date of the download. These logs may be kept in an archived manner, on the server or elsewhere, provided that the information reconciles across replicated storage and that the information can be produced within 24 hours upon request. In any event, download logs for the previous 72 hours shall be immediately accessible. *(b) Interim Storage or actuation of Download Packages.*
                                 If Download packages are loaded to interim storage and not to the Electronic Player Station or peripheral for immediate activation, then the interim storage shall be: (1) A component within the logic area of the client device; or (2) A separate device, such as a processor board, that resides within a logic area of the client device and meets the requirements of: (i) Section 547.5; (ii) Section 547.10(a), if residing in a separate cabinet; (iii) Section 547.11; (iv) Section 547.1(d); (v) Section 547.16(g); and (vi) Section 547.17. *(c) Actuation of Download Packages.*

                                 (1) All removable program storage media such as ROMs, EPROMs, Flash ROMs, CD-ROMs, DVDs etc. shall be clearly marked with sufficient information to identify the software and version or revision level contained. (2) All removable program storage media shall maintain an internal checksum or signature of its contents. Verification of this checksum or signature is to be performed after every restart and, if the verification fails, the Electronic Player Station shall enter a fatal error state. (b) 
                                *Non-writeable program storage media.*
                                 (1) All EPROMs and Programmable Logic Devices (PLDs) that have erasure windows shall be fitted with covers over their erasure windows. (2) All unused areas of EPROMs shall be written with the inverse of the erased state, e.g., zero bits (00 hex) for most EPROMs, random data, or repeats of the program data. (3) Flash memory storage devices intended to have the same logical function as ROM, i.e. not to be dynamically written, shall be write protected or otherwise protected from unauthorized modification. (4) Re-writeable CD-ROMs shall not be used. (5) The write cycle shall be closed or finished for all CD-ROMs such that it is not possible to write any further data to the CD. (6) Write protected hard disks are permitted if the means of enabling the write protect is easily viewable and can be sealed in place. (c) 
                                *(Re-)Writeable program storage media.*
                                 (1) (Re-)writable program storage, such as hard disks, Flash memory, writable CD-ROMs, and writable DVDs, may be used provided that the verification requirements of § 547.19(b) and § 547.18(a)(6) are met. (2) Program storage is structured so there is an obvious separation of fixed data (e.g. program, fixed parameters, DLLs) and variable data. (d) 
                                *Identification of program storage media.*
                                 All discrete program storage media (e.g.  EPROM, CD-ROM) shall be uniquely identified, displaying: (1) Manufacturer; (2) Game name; (3) Game development number or variation; (4) Version number; (5) Jurisdiction; (6) Type and size of media; and (7) Location in Electronic Player Station, if critical (e.g.  socket position 3 on PCB).
 § 547.21
  This section provides minimum standards for random number generators (RNGs) used with the play of Class II games and for cryptography. (a) 
                                *Properties.*
                                 All RNGs shall produce output having the following cryptographic properties: (1) Statistical randomness; (2) Unpredictability; and (3) Non-repeatability. (b) 
                                *Statistical Randomness.*
                                 (1) Numbers produced by an RNG shall be statistically random individually and in the permutations and combination used in the application under the rules of the game. For example, if a Bingo game with 75 balls has a progressive winning pattern of the five numbers on the bottom of the card and the winning of this prize is defined to be the five numbers are matched in the first five balls drawn, the likelihood of each of the 75C5 combinations are to be verified to be statistically equal. (2) Numbers produced by an RNG shall pass the statistical tests for randomness to a 99% confidence level, which may include: (i) Chi-square test; (ii) Equi-distribution (frequency) test; (iii) Gap test; (iv) Poker test; (v) Coupon collector's test; (vi) Permutation test; (vii) Run test (patterns of occurrences shall not be recurrent); (viii) Spectral test; (ix) Serial correlation test potency and degree of serial correlation (outcomes shall be independent from the previous game); and (x) Test on subsequences. (c) 
                                *Unpredictability.*
                                 (1) It shall not be feasible to predict future outputs of an RNG, even if the algorithm and the past sequence of outputs are known. (2) Unpredictability shall be ensured by re-seeding or by continuously cycling the RNG, and by providing a sufficient number of RNG states for the applications supported. (i) Re-seeding may be used where the re-seeding input is at least as statistically random as, and independent of, the output of the RNG being re-seeded. (ii) The number of RNG states shall be larger than the number of possible outcomes in the application for which the RNG is used by at least a factor of 108. (d) 
                                *Non-repeatability.*
                                 The RNG shall not reproduce the same output stream that it has produced before, nor shall any two instances of an RNG produce the same stream as each other. This property shall be ensured by initial seeding that comes from: (1) A source of “true” randomness, such as a hardware random noise generator; or (2) A combination of timestamps, parameters unique to a server or Electronic Player Station, previous RNG outputs, etc. (e) 
                                *General requirements.*
                                 (1) Game software that calls an RNG to simulate an event of chance shall immediately use the output returned in accordance with the game rules. (2) RNG outputs shall not be arbitrarily discarded or selected. (3) Where a sequence of outputs is required, the whole of the sequence shall be used in accordance with the game rules. 
                                ( print page 46358) (f) 
                                *Scaling algorithms and scaled numbers.*
                                 An RNG that provides output scaled to given ranges shall: (1) Meet the requirements of paragraphs (a) through (d) of this section and be independent and uniform over the range; (2) Provide numbers scaled to the ranges required by game rules, and notwithstanding the requirements of paragraph (e)(2) of this section, may discard numbers that do not map uniformly onto the required range but shall use the first number in sequence which does map correctly to the range; (3) Be capable of producing every possible outcome of a game according to its rules; and (4) Use an unbiased algorithm. A scaling algorithm is considered to unbiased if the measured bias is no greater than 1 in 100 million. (g) 
                                *RNGs used for cryptography.*
                                 (1) RNGs used for cryptography shall: (i) Be separate from RNGs used for other purposes; (ii) Be accessible only by the components that implement the security functionality; (iii) Not weaken security by providing a point of attack on the security protocols that it supports; (iv) Have a number of states at least as great as the encryption strength—for example, an RNG using 128 bit encryption shall have at least 2128
                                 states; (v) Make use of an entropy source in its initial and ongoing seeding, unless a security protocol requires that a recipient's (pseudo) RNG supplied with correct key information reproduces the same sequence as the sender's RNG; and (vi) Be re-seeded at a rate that makes cryptoanalytic attack impractical. (2) RNG components used for cryptography shall notify callers in the event of a malfunction. (3) Security system components reliant on RNG outputs shall cease to operate when a fault is detected in the operation of the RNG and security can no longer be assured.
 § 547.22
  This section provides minimum standards for data communications with gaming equipment, or components, used with the play of Class II games. This section also provides minimum standards for communications between the Class II gaming equipment and any equipment external to it. (a) 
                                *Electrical requirements.*
                                 (1) Communication interfaces on Electronic Player Stations shall have at least 3 Kv of line isolation to achieve mains power static discharge immunity from lightning and other static discharges. (2) When subjected to electrostatic discharges, Electronic Player Stations shall not interfere with the operation of any other attached equipment via local data communications cabling. (3) When subject to disruption of the mains power, Electronic Player Stations shall not interfere with the operation of any other attached gaming device via local data communications cabling. (4) Electronic Player Stations and successive devices in any communications chain shall be powered from different sources. (5) There shall be no mains ground interconnections via data cabling between Electronic Player Stations powered from different supply circuits unless adequate line isolation is in place. Note that RS-232-C may be used only if the two communicating devices are powered from the same supply circuit and the cable length between the two devices is less than 15 feet. (b) 
                                *Functional requirements, generally.*
                                 (1) Data communications shall be designed to allow transfer of game play financial information and event data to a casino operating system on a regulator schedule or on demand. (2) After gaming equipment has been de-activated, activating the gaming equipment requires manual intervention by the gaming operator, except that: (i) An Electronic Player Station may automatically re-activate upon restoration of communications following a communications failure, unless it determines that lock-up state should apply due to some other cause; and (ii) If gaming equipment is automatically de-activated at the end of the venue's current session (e.g., an automatic deactivation date/time calendar exists), it is permissible for the casino monitoring system to automatically re-activate the gaming equipment when the next permitted session commences. (3) When more than one Electronic Player Station or client communicates using the same transmission medium, the communications port shall operate at a communication speed within a 1% tolerance of the required communications speed, unless the specific communications protocol allows a greater tolerance. (c) 
                                *Protocol requirements.*
                                 (1) All communications shall be made via a protocol-based communications scheme unless otherwise authorized by the tribal gaming regulatory authority. (2) Communications protocols shall include: (i) Error control; (ii) Flow control; and (iii) Link control (remote connection). (3) For serial communication links, data communications shall make use of suitable error detection algorithms. At a minimum, Cyclic Redundancy Checks (CRCs) shall be used for this purpose. The use of only parity or simple checksum byte is not acceptable. (4) Data communications shall be able to withstand varying error rates. (d) 
                                *Communications failures and recovery.*
                                 (1) During any communications failure and recovery, no data shall be lost, duplicated, modified or re-ordered. (2) Failures and re-establishment of communications shall be logged as events by the Electronic Player Station or server. (3) On program resumption, e.g., after a power restart of the equipment, any communications to an external device shall not begin until the program resumption routine, including self-tests, is completed successfully. (4) When a non-correctable critical storage error has occurred, the data on the Electronic Player Station can no longer be considered reliable. Accordingly, any communication to external devices shall cease immediately and an appropriate message shall be displayed. (e) 
                                *Wireless communications.*
                                 Wireless communications may be used within and to Class II gaming equipment provided the following requirements are met: (1) Wireless access points must be installed so the general public cannot physically access them. (2) External switches that reset device configuration to a default state must be disabled unless that default state meets the requirements of this paragraph (e). (3) Open or unencrypted Wi-Fi communications are prohibited. (4) 802.11i in combination with 802.1X and Radius authentication servers is an acceptable method for securing wireless communications. The device/user authentication mechanism must employ digital certificates, two-factor methods or similarly strong techniques. Use of simple passwords is not acceptable. (5) WPA and WEP are not acceptable methods for securing wireless communications. (6) VPNs shall be used for end-to-end communication, and any wireless portion of the connection must meet the requirements of this paragraph (e). (7) The portions of the network that contain wireless access points must be separated from the rest of the network by firewalls. (8) Wireless access points must have MAC filtering capabilities. MAC filters on Wireless Access Points must be 
                                ( print page 46359)
                                enabled (only devices using registered MAC addresses can connect). (9) The SSID in 802.11 networks must be changed to be different to the default factory setting. (10) The SSID in 802.11 networks must not be broadcast in response to broadcast probe requests. (11) Peer-to-peer networking (a.k.a. ad-hoc mode) shall be disabled on all wireless devices, except for the purpose of communicating with peripheral devices in a small-radius personal area network. (12) The Beacon Interval in 802.11 networks must be increased to the maximum value of 67 seconds. (13) Access through SNMP must be restricted: (i) SNMP must be disabled unless it is in active use through a network management system. (ii) SNMP and SNMP v2 are not acceptable. (iii) If SNMP v3 is proposed, the configuration must change read and write community strings away from default values (typically “public” and “private” respectively). (14) DHCP must be disabled, which means statically configuring IP addresses into end devices. (15) Username and passwords must be changed from factory default. (16) Insecure usernames and passwords (e.g. anonymous/anonymous) must be deleted from any Wireless Access Point. (17) Wireless communications may not be used to circumvent restrictions limiting gambling to the casino floor or other designated areas. Implementation, therefore, of wireless communications may require the tribal gaming regulatory authority to implement requirements for blocking capabilities in various locations.
 § 547.23
  This section provides minimum standards for encryption and hashing in client-server implementations used with the play of Class II games. (a) 
                                *Encryption generally.*
                                 (1) Communications across public areas shall be encrypted. (2) Communications across publicly accessible networks shall be encrypted. These include Ethernet networks or any networks that use routers, all wireless communications, communications across wide area networks. (3) Proprietary or closed loop networks need not be encrypted but shall be physically secure such that intrusion is detectable. (4) Notwithstanding paragraphs (a)(1) through (3) of this section, communications containing any of the following need not be encrypted but must be protected against illicit alteration, unless contained within a single logic area: (i) Software uploads and downloads; (ii) Game outcome information; and (iii) Progressive jackpot meters, parameters, configuration, and win messages. Note that message authentication codes based upon hashing algorithms that meet the requirements of paragraph (c) of this section are sufficient to meet this requirement. (5) Notwithstanding paragraphs (a)(1) through (3) of this section, communications containing any of the following shall be protected from eavesdropping 
                                *i.e.*
                                 encrypted, and from illicit alteration unless the communication is contained within a single logic area: (i) RNG seeds and outcomes; (ii) Encryption keys, where the implementation chosen requires transmission of keys; (iii) PINs; (iv) Passwords; (v) Ticket voucher transactions; (vi) Transfers of money to/from player accounts, pursuant to § 542.13(o)(3)(iii) of this chapter; (vii) Transfer of money between gaming equipment, pursuant to § 542.13(o)(3)(iii) of this chapter; (viii) Player tracking information; (6) If key data files containing pull tabs game results are maintained on a disk on the server and/or clients, the files shall be encrypted. (b) 
                                *Encryption algorithm.*
                                 Any encryption required by this part shall use an algorithm that meets the following requirements: (1) Encryption algorithms are to be demonstrably secure against cryptanalytic attacks. Encryption algorithms that media reports have demonstrated to be broken are not demonstrably secure. The following algorithms are demonstrably secure: (i) SSL/TLS (Using a Public Key algorithm); (ii) IPSec—(Potentially a “Hardware” solution); (iii) Triple DES (Symmetric algorithm using a 112 bit key); (iv) IDEA (Symmetric algorithm using a 128 bit key); (v) Blowfish (Symmetric algorithm using a 448 bit key); (vi) Twofish (Symmetric algorithm using a 128-bit, 192-bit or 256-bit key); and (vii) AES (Symmetric algorithm using a 128-bit, 192-bit or 256-bit key). (2) The minimum width (size) for encryption keys is 112 bits for symmetric algorithms and 1024 bits for public key algorithms. (3) If a symmetric algorithm is chosen, a key rotation methodology ensuring encryption keys are changed no less than every 30 days shall be adopted. The key rotation process shall be automated. (4) There shall be a secure method implemented for changing the current encryption key set. An example of an acceptable method of exchanging keys is the use of public key encryption techniques to transfer new key sets. (5) Other proprietary encryption and authentication methods, including the use of a Virtual Private Network (VPN), are permissible provided they provide protection against eavesdropping and illicit modification equivalent to the methods described paragraphs (a) and (b) of this section. (c) 
                                *Hashing algorithms.*
                                 Any hashing required by this part shall use an algorithm having the following characteristics: (1) The hashing algorithm shall combine the entire contents of the files or data being processed. (2) The hashing algorithm shall combine the bits in a complicated and cross-interactive manner. (3) The hashing algorithm shall detect at least 99.998% of all possible altered files or data. (4) The hashing algorithm shall be cryptographically strong, i.e. by looking at the hash result there is no practical way, in a given period of time, to derive any part of the original data. (5) If the hashing algorithm uses seeds (algorithm coefficients), the “seed” information shall influence the behavior of the algorithm in a non-trivial way.

                                *Disclaimers.*
                                 The Electronic Player Station shall at all times display: (1) “Malfunctions void all pays and plays” (2) “Actual Win Determined by Bingo [or other applicable Class II game] Play. Pay Table Lines and Reels for Entertainment Only.” (c) 
                                *Stickers.*

 § 547.25
  The section provides general standards for a client-server implementation used with the play of Class II games to interface with a casino monitoring or accounting system. This section also provides general standards for servers acting as monitoring or accounting systems. (a) 
                                *Monitoring or accounting system interface, generally.*
                                 (1) Client-sever implementations used with the play of Class II games shall be interfaced to an on-line monitoring system that processes security, maintenance and financial data and provides accounting data to the operator. An on-line monitoring system is required in all cases where remote monitoring is allowed. (2) Data communications with the casino monitoring system shall meet the requirements of § 547.22. (3) An on-line monitoring system may be located locally within a facility or remotely outside of the facility. (4) The on-line monitoring at the minimum shall provide a statistical analysis for verification of correct performance/return to player for each Electronic Player Station. (b) 
                                *Servers acting as monitoring or accounting systems.*
                                 The components or functions of an on-line monitoring system may be embedded within the game server. If so, the following requirements apply: (1) The server shall not permit the alteration of any information. (2) The server shall have a backup and archive utility to allow the operator to save data in critical memory in the event of a system failure. In the event of a catastrophe that results in a failure whereby the servers cannot be restarted, it shall be possible to reload the system to a backup point and to fully recover the contents of that backup.
 § 547.26
  (a) 
                                *Tribal gaming regulatory authority approval.*
                                 (1) A tribal gaming regulatory authority may approve a variance from the requirements of this part for a gaming operation if it has determined that the variance will achieve a level of security and game integrity sufficient to accomplish the purpose of the standard it is to replace. (2) For each enumerated standard for which the tribal gaming regulatory authority approves a variance, it shall submit to the Commission Chairman, within 30 days, a detailed report, which shall include the following: (i) A detailed description of the variance; (ii) An explanation of how the variance achieves a level of security sufficient to accomplish the purpose of the standard it is to replace and of any equipment or software to be implemented with the variance; (iii) An evaluation of the variance from an independent testing laboratory recognized by the Commission pursuant to § 546.9(f) of this chapter; and (iv) Evidence that the tribal gaming regulatory authority has approved the variance. (3) In the event that the tribal gaming regulatory authority or the tribe chooses to submit a variance request directly to the Chairman, it may do so without the approval requirement set forth in paragraph (a)(2)(iv) of this section. (b) 
                                *Review by the Chairman.*
                                 (1) Following receipt of the variance approval, the Chairman or his designee shall have 60 days to concur with or object to the approval of the variance. (2) Any objection raised by the Chairman shall be in the form of a written explanation and be based upon the following criteria: (i) There is no valid explanation of why the gaming operation should have received a variance approval from the tribal gaming regulatory authority on the enumerated standard; or (ii) The variance as approved by the tribal gaming regulatory authority does not provide a level of security or game integrity sufficient to accomplish the purpose of the standard it is to replace. (3) If the Chairman fails to object in writing within 60 days after the date of receipt of a complete submission, the variance shall be considered concurred with by the Chairman. (4) The 60-day deadline may be extended, provided such extension is mutually agreed upon by the tribal gaming regulatory authority and the Chairman. (c) 
                                *Curing Chairman's objections.*
                                 (1) Following an objection by the Chairman to the issuance of a variance, the tribal gaming regulatory authority shall have the opportunity to cure any objections noted by the Chairman. (2) A tribal gaming regulatory authority may cure the objections raised by the Chairman by: (i) Rescinding its initial approval of the variance; or (ii) Rescinding its initial approval, revising the variance, approving it, and resubmitting it to the Chairman. (3) Upon any re-submission of a variance approval, the Chairman shall have 30 days to concur with or object to the re-submitted variance. (4) If the Commission fails to object in writing within 30 days after the date of receipt of the re-submitted variance, the re-submitted variance shall be considered concurred with by the Chairman. (d) 
                                *Appeals.*
                                 (1) Upon receipt of objections to a re-submission of a variance, the tribal gaming regulatory authority shall be entitled to an appeal to the full Commission in accordance with the following process: (i) Within 30 days of receiving an objection to a re-submission, the tribal gaming regulatory authority shall file its notice of appeal. (ii) Failure to file an appeal within the time provided by this section shall result in a waiver of the opportunity for an appeal. (iii) An appeal under this section shall specify the reasons why the tribal gaming regulatory authority believes the Chairman's objections should be reviewed, and shall include supporting documentation, if any. (iv) The tribal gaming regulatory authority shall be provided with any comments offered by the Chairman to the Commission on the substance of the appeal, and the tribal gaming regulatory authority shall have the opportunity to respond to any such comments. (v) Within 30 days after receipt of the appeal, the Commission shall render a decision based upon the criteria contained within paragraph (b)(2) of this section unless the tribal gaming regulatory authority elects to wave the 
                                ( print page 46361)
                                30-day requirement and to provide the Commission with additional time, not to exceed an additional 30 days, to render a decision. (vi) In the absence of a decision within the time provided, the tribal gaming regulatory authority's resubmission shall be considered concurred with and become effective. (2) The tribal gaming regulatory authority may, without resubmitting the variance, appeal the Chairman's objection to the approval of a variance to the full Commission by filing a notice of appeal within 30 days of the Chairman's objection and complying with the procedures set out in paragraph (d)(1) of this section. (e) 
                                *Effective Date of variance.*
                                 The gaming operation shall comply with standards that achieve a level of security or game integrity sufficient to accomplish the purpose of the standard it is to replace until such time as the Chairman objects to the Tribal gaming regulatory authority's approval of a variance as provided in paragraph (b) of this section. (f) 
                                *Discretion.*
                                 Concurrence in a variance by the Chairman or by the Commission is discretionary and variances will not be granted routinely. The gaming operation shall comply with standards at least as stringent as those set forth in this part until such time as the Chairman or the Commission concurs with the tribal gaming regulatory authority's approval of the variance.
 Dated: August 1, 2006. Philip N. Hogen, Chairman. Cloyce V. Choney, Associate Commissioner.
