DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENTS
Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the disclosure. The features and advantages of the disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the present disclosure will become more fully apparent from the following description and appended claims, or may be learned by the practice of the disclosure as set forth herein.
Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the disclosure.
The disclosed embodiments may concern a method and apparatus that may provide an integrated secure wireless solution to enable users to conduct their mission/business using secure wireless. The disclosed embodiments may enable and facilitate improved collaboration and productivity through increased mobility. Furthermore, users will benefit from a reduction in operating and maintenance (O&M) costs. The disclosed embodiments may enable these improvements in productivity by allowing the user to securely access their data as well as custom and commercial, off-the-shelf (COTS) applications in a Sensitive Compartmented Information Facility (SCIF) or other proprietary or security-sensitive area.
The disclosed embodiments may also provide significant benefits to rapid deployments for tactical environments overseas by reducing the amount of equipment shipped, significantly improving the time to bring a secure network up while providing mobility to the overseas personnel, such as military, government or civilian personnel. Applications may be integrated and utilized in a secure manner.
Reductions in O&M costs may be attributable to the reduction in wired infrastructure, replacement of regular or Voice Over Internet Protocol (VOIP) phones and the ability to do full motion video, voice and data securely in both classified environments and corporate environments while reducing the costs to outfit new work areas or new buildings.
Cyber security may be integrated in the disclosed embodiments and through triple encryption while preventing data compromise by not allowing any data to be stored on the end-points. This layered commercial encryption may provide secure wireless access to a multitude of customers from government and military users (up to the top secret information level) as well as commercial enterprises, such as banking or healthcare (for electronic patient records, etc. for example).
In this manner, the three layers of encryption may exist within the infrastructure of the disclosed embodiments to protect sensitive data and adhere to the highest government standards.
FIGS. 1A and 1B are exemplary diagrams of a wireless communication network environment 100 in accordance with a possible embodiment of the disclosure. In particular, the communication network environment 100 may include one or more exemplary communication devices such as wireless processing devices 105 which may communicate through a first communication network 115 through one or more access points 110. A wireless local area network controller 120 receives the communication (or data) and it reaches the server 135 through the firewall 125 and a second communication network 130.
Communications networks 115, 130 may represent any communications network used to communicate with other entities, including the Internet, an intranet, a radio network, a wireless network, hardwired network, satellite network, etc. The exemplary wireless processing device 105 may be any device capable of sending and receiving messages and/or attachments, such as a processing device, a mobile communication device, a portable computer, a desktop computer, a server, a network router, a gateway device, or combinations of the above, for example.
FIG. 1A shows an exemplary end-to-end view of this infrastructure and the varying layers of encryption present at each level with respect to Wireless-Fidelity (Wi-Fi) communications. Note that while FIG. 1A shows a laptop computer, any other wireless device that uses Wi-Fi may be used, such as personal digital assistants (PDAs) or other wireless communications device. Note also, that while various components are illustrated between the exemplary wireless processing device 105 and the server 135, these components and their arrangement may vary as known to one of skill in the art.
Initially, end-user mobile devices may be provisioned with 802.1x certificates by information technology (IT) personnel at an offsite location, for example. These certificates may enable the mobile devices to connect to the secure wireless access points 110 which may be deployed at the user's site. All data or communications 145 between the end-user exemplary wireless processing device 105 and the wireless access points 110 are encrypted as a first encryption layer 150 following a Wi-Fi Protected Access (WPA2) standard, such as a session or presentation layer encryption (e.g., Advanced Encryption Standard (AES) AES-128 encryption), for example. Note that FIG. 1B illustrates a close-up view of the three layers of encryption 140 shown in FIG. 1A.
The second layer of encryption 155 may be achieved through network layer encryption by connecting to a secure Virtual Private Network (VPN) server with a user login, utilizing a robust encryption method, such as the 1024-bit, 2048-bit or any other future standard key AES-256, for example. The user login may include any combination of biometrics, hardware tokens and secure passwords, for example. To provide added security, the 1024-bit, 2048-bit or any other future standard keys required by AES-256 to communicate through the VPN may be rotated periodically, such as every two minutes, for example.
Once a user is authenticated through the VPN, they will then need to provide an additional set of credentials to login to the Virtual Desktop Infrastructure (VDI) client. This third layer of encryption 160 may provide the user access to their normal work environment and may utilize the user's existing hardware and infrastructure. This third layer of encryption 160 may be transmitted through the Secure Sockets Layer (SSL) using data layer encryption (e.g., 128-bit, Rivest Cipher 5 (RC5) encryption), for example. Since the communication device 105 may be a virtual desktop, all data may remain stored on the user's secure back-end so that only presentation layer information may be sent through the three layers of encryption, for example.
FIGS. 2A and 2B are exemplary diagrams of another wireless communication network environment 200 in accordance with a possible embodiment of the disclosure. Users may also benefit from the added productivity of accessing their data through specialized applications on communication devices 205, such as PDAs, smartphones, etc. while out of range of secure wireless access points. This access may be accomplished using a connection to a secure network from the Internet 215 via 3G (third-generation), 4G (fourth-generation), or any other future standard of communications, for example.
Three layers of encryption 240 may be maintained through this mode of access with a solution utilizing the disclosed embodiments. Due to the realities of unreliable network connections and limited bandwidth in the field, it may be desirable for mobile communication device 205 users to have offline access to some information. In addition to credentials required to unlock those devices 205, data-at-rest on the mobile communication device 205 and applications which access information on the secure network may be sandboxed and encrypted by software installed on the mobile communication device 205 before it is deployed. In this instance, the first encryption layer 250 for data 245 to be communicated may be a session or presentation layer encryption (e.g., AES-192 encryption), for example.
Secondly, a secure VPN connection 225 may be made between the mobile communication device 205 and the network using available 3G), 4G, or any other future standard of communications access, for example. This connection may use a second layer of encryption 255, such as a session or presentation layer encryption (e.g., AES-192 encryption), for example. Finally, applications providing e-mail, calendar, collaboration, virtual desktop or specialized applications which support mission needs may present an additional third layer of authentication and encryption, such as a network layer encryption (e.g., 1024-bit, 2048-bit or any other future standard key AES-256 encryption).
