P2P Network Monitoring System
Towards Traceability of Confidential File Leakage

Ruo Ando
Senior Researcher, Traceable Secure Network Group, Information Security Research Center
In March 2006, Ruo Ando completed the Media and Governance Advanced Doctoral Course at the Graduate
School of Media and Governance, Keio University (Ph.D. in media and governance). In April 2006, he joined the
National Institute of Information and Communications Technology (NICT) and has been engaged in the research
activities on information security, cloud computing authentication, access control, and application layers network
monitoring.

P2P Network Monitoring System

Algorithm for Accelerating the Tracing of Information Leakages

The peer-to-peer (P2P) information network leakage*1 (of unintentional divulgence of confidential files) has given rise to social
issues in recent years. While a P2P network contributes to enhancing convenience of the Internet owing to the high speed and efficiency of file transfers, it is not compatible with the monitoring approach of conventional client server models, resulting in the
difficulty in determining the network operating status indicating
what is happening on the network. Additionally, the issues of security incidents such as extensive distribution of illegal files containing viruses and the information leakage through P2P networks are
significant. Since monitoring of P2P network needs to be a broadarea, efficient monitoring is enabled by detecting supernodes withmassively collected information. Traceable Network Group has developed a "probe network" for tracing and verifying the file distribution status and alteration histories on P2P networks, and is surveying the status of nodes linked to the P2P networks.

What our group is now considering as critical points in tracing
information leaks on a P2P network includes the following two approaches:(1) to detect supernodes and query them to identify thefile distribution status and (2) to detect altered or re-issued files byapplying an algorithm to determine the degree of similitude.

The color of each plot point indicates the information volume on each node.

Detecting Supernodes and Tracing the Status of File Distribution Status
On a P2P network, there is a single functional element called"supernode" that works at the center of a cluster (the agglomerated
content of similar files). The P2P network monitoring system aims
at monitoring and grasping the file distribution status in accordancewith the details of a leaked file, by detecting and querying the supernode.

The color of each plot point indicates the information volume on each node.

Reinforcing the Systems for Wide-Area Network Monitoring
Since the P2P network that covers a wide area generates an enormous volume of monitored data, providing virtual monitoring
nodes is an effective means to enhance the intensity of data accumulation. Thus, the system enables the provisioning*3 for a monitoring task of which traffic log varies dynamically and thus canhardly be assessed.

TBNAN, a Network Traffic
Monitoring and Analysis System
Towards New Generation Traceable Networks
Tao BanExpert Researcher, Traceable Secure Network Group, Information Security Research Center
Dr. Tao Ban received his Ph.D. degree in Engineering from Kobe University, Japan, in 2006 and since then he has
been working as an expert researcher in NICT. His current research interests include network monitoring andanalysis, network attack countermeasures, malware analysis, data mining, and machine learning. Ph.D. (Engineering)

BackgroundTraceable Network Group is now working on the developmentof IP traceback technology to fight against cyberterrorism attacks
such as (distributed) denial of service (DDoS). By smoothing thecollaboration and coordination among interconnecting ISP networks, IP traceback technology enables discovery of the attack
path for an attack with spoofed IP address. However, as a reactive
tool to locate attack sources and alleviate the impact of DDoS, an
IP traceback system cannot operate autonomously but rely on otherentities for attack detection. Moreover, performing IP traceback
needs to intercept the communication channel and thus is subject touser privacy violation; it may impose load (more or less dependingon specific implementation) on the traceback servers and line capacity and thus affects the performance of user network. In the following, we introduce our recent study of the Trace Back Network
Analyze (TBNAN) – a starting system for the IP traceback.
Equipped with attack-identifying and abnormality-detecting functions, TBNAN seeks to ensure the legitimacy and improve the effectiveness of an IP traceback system.
The TBNAN system, as a network monitoring and analyzing

system (NMAS), is equipped with a function that detects the anormaly status or performance drop in the monitored computer network in an intellectual manner and sends system warnings to the
network administrator. Hence, an NMAS could contribute to theprotection from threats adversely affecting the network and minimization of risk and loss caused by malware*1 or abuse of important Internet resources. NMASes often find useful applications in:(1) network server load monitoring and management, (2) intrusion
sensing against external intrusions, (3) IP traceback for locating attackers using IP address spoofing, and (4) system monitoring for
tracking virus propagation, malware activities, and botnet*2 motions.

Mechanism of TBNAN
TBNAN has been developed to be an NMAS for high-speed networks and complex protocols. The TBNAN system is composed ofa packet processor, a computation server, a database server, and a
web server (Figure 1).
(1)The packet processor
The packet processor captures traffic going through an accesspoint, extracting statistical information from the traffic, and theforword the data to the computation server. Here, statistical quantities of time, space, and flow rate are extracted from the data link
layer, network layer, and transport layer. The packet processor does
not inspect the payload information to protect user privacy. Therefore, it circumvents reverse engineering of protocols with encrypted payload and meets the performance requirement of real-timemonitoring in a next generation broadband network.
(2)The computation serverThis server creates prediction models by applying the data mining technology to received data.
[Statistical classification] This is a statistical process to categorize
network streams into known classes based on their statistical characteristics. In the case shown in Figure 2, the system identifies
whether or not the involved host pertains to P2P nodes by referringto the traffic related to the host. The classification is performed
based on the two quantities with respect to a host, namely, (a) the
number of kept connections in a unit time frame and (b) the packet
volume with in the same time window. The decision function indicated with the white dotted line predicts the probability of a hostbeing a P2P host. In the figure, nodes on the right side of the dottedline are predicted as P2P hosts.
[Anomaly detection] This method builds a model of normal network streams and detect deviations from the normal model in observed streams and predict them as anomaly states. In the case of
Figure 3, the anomaly detection algorithm helps to identify port
scan attackes by monitoring the communications between a hostand the Internet, The detection refers to the following two quanti-

Figure 2●Grouping P2P hosts through statistical learning

ties: (a) the number of source ports that have appeared in a unit
time frame and (b) the type of TCP-Flags that have appeared in thesame time window. Anomaly spots can be detected during the port
scan in reference to the decision function indicated by the thresholdplane (normal traffic under the plane and port scan above theplane) given in Figure 3.
In addition to the above mentioned methods, we are positively
incoorperating other intelligent analytical tools such as statisticalanalysis and clustering metods*5 into the TBNAN system.
(3)Database and web server
These units provide the user with the indexing and visualization
services of the data imported from the computation server.

Future Perspective
In the opening age of cloud computing, computer applications
will depend more heavily on networks, and at the same time, thenetwork infrastructure and protocols will presumably gain further
complexity. Therefore, the monitoring and analysis of network traffics will become an increasingly challenging task. Striving for theobjective to realize the new generation networks with further enhanced stability and reliability, we aim at enabling realtime incident response under the broadband environment. To this end, weplan to incorporate the latest achievements in the theoretical fieldof data mining and machine learning as well as the paractical technologies such as parallel computing, hardware realization, and
GPGPU computing into the TBNAN system.

An Oblivious Secret Key Encryption
Scheme and Its Applications
Toward Privacy-Preserving Traceable Networks

Ryo Nojima
Senior Researcher, Traceable Secure Network Group, Information Security Research Center
Ryo Nojima received the Ph.D. degree in the Information Science in 2005. In 2005, he jointed as a postdoctoral
fellow of Tokyo University. In 2006, he joined as a researcher of the Information Security Research Center, National
Institute of Information and Communications Technology (NICT). His interests include applied cryptography andnetwork security.

Background of the Research Activities
With the rapid progress of the Internet, the network security related issues such as computer viruses and denial of service (DOS)attacks are increasingly taken up. Among those issues, we, theTraceable Network Group, have so far paid attention to the specifictechnology called "IP-Traceback technology" for tracing illegal users who have committed the DOS attack. While the IP-Traceback
technology is said to be very useful, it has the potential risk of depriving not only illegal users but also legitimate users of their privacy. Our group has thus carried on the research and developmentof such an IP-Traceback technology that can preserve the privacy.
The issues in the conventional IP-Traceback and the privacypreserving IP traceback can be simplified as follows: First, imagine
two users (Hanako and Taro). Let us assume that Taro keeps the setof IP addresses A= {a1, …, an}, while Hanako has an IP address "a".
The intent of Hanako is to find whether “A” contains an "a". This
problem can be resolved by Hanako sending the "a" to Taro, andTaro checking whether "a" is included in "A". In actual IP-Traceback practice, a similar interaction is performed by assuming

Hanako being at the send end and Taro at the receive end. In contrast, privacy-preserving IP-Traceback raises somewhat more difficult issues. To implement this technology, it is imperative to ensurethat Taro does not disclose "A" and Hanako "a" to check whether"a" is included in "A". Our group has successfully resolved this apparently insoluble problem by developing and applying a technology called Oblivious Secret Key Encryption Scheme. The following
summarizes the Oblivious Secret Key Encryption Scheme and introduces its applications.

Secret Key Encryption Scheme
In the Secret Key Encryption scheme, message "M" can be encrypted by using a secret key "SK". This encrypted message is represented with the abbreviation "Enc" (SK, M) where only the person who keeps the secret key SK can extract M from Enc (SK, M).
Conversely, any person without SK cannot get any piece of information relevant to M. Typical Secret Key Encryption scheme includes DES (Data Encryption Standard) and AES (Advanced Encryption Standard).

To obtain M, SK isneededFigure 1●Illustration of Secret Key Encryption

Oblivious Secret Key Encryption Scheme
The Oblivious Secret Key Encryption Scheme (hereafter abbreviated as OEP) is a cryptographic protocol between two parties(Taro and Hanako).
Taro keeps the secret key SK to the secret key encryption, while
Hanako has the message M. This protocol enables the computationof the ciphertext C = Enc (SK, M), while keeping SK and M in secret. In this protocol, Hanako can obtain C, whereas Taro cannot
get any piece of information on C (Figure 2).
Our group has succeeded in the design and development of the
OEP of the Secret Key Encryption scheme DES.
In this case, the term "oblivious" literally means "unaware".
Since each of Taro and Hanako is "unaware" of the other party's input, the term "oblivious" has been employed for this protocol.

Applications of the OEP
IP-Traceback
In the privacy-preserving IP-Traceback technology, each of Taroand Hanako has to conceal information pertaining to the other party when verifying whether “a” is included in A = {a1, …, an}. This
problem can simply be resolved by using the OEP in the followingway:( 1) Taro selects the secret key SK of the Secret Key Encryption
Scheme and sends "Enc (SK, a1),…, En c(SK, an)" to Hanako.
( 2) Hanako uses the OEP to get Enc (SK, a). Then, when "Enc
(SK, a1),…, Enc (SK, an) includes any item that will be identicalwith Enc (SK, a), she concludes that “a” is included in “A”.
Since the use of OEP prevents the mutual leak of SK and “a”,
the secret data “a” of Hanako will never be leaked to Taro. Further,since SK is not leaked to Hanako, there is no risk that Taro's secretdata A should be leaked from n pieces of ciphertexts to any party(Figure 3).

Cloud Storage
The technology for storing files in external servers is currently
attracting interest to minimize investments in the infrastructure including servers and to realize the data consolidation. When an enterprise or other organization is to store files in external servers, theencryption of those files is obviously required. In view of userfriendliness, keyword-based retrieval may be employed. However,
how can the retrieval process be applied to those files that are encrypted? The OEP enables the keyword retrieval of a text that remains encrypted.

preserving SK and M secret

Young Learners Move Away from the Sciences―Report on the Exhibits at the 2010 Tokyo "Youngster’s Science Festival" in Koganei―

The "2010 Youngster’s Science Festival Tokyo Convention in Koganei" was held on Sunday, Sept. 12, at the Koganei Campus of Tokyo
Gakugei University, where NICT presented its exhibits.
Despite such a hot day above 34℃, a number of children and their family members visited the venue. Since 1992 this Youngster's Science Festival (National Convention) has been held each year for junior high and high school students to stop moving away from science,and to offer experiencing fascination of science. Amidst various events organized throughout the nation, this regional event (Tokyo Convention), allows youths to experience the exciting aspects of natural science and thereby foster their sensibility and sharp intellect. Thus, a number of organizations, associations, and individual volunteers living in Tama area, centered around Koganei City, participated in the event.
NICT gave three presentations: "Let's watch the space weather -- Weekly Spatial Weather News --", "Let's enjoy the multi-sensory interactions!" and "Let's create clouds!""Let's watch the space weather -- Weekly Space Weather News --", children were curious to unusual "Space Weather Forecast" and intently stared at the screen. Similarly at the booth of "Let's enjoy the multi-sensory interactions! ", visitors experienced the multi-sensory interaction system, which has been developed by NICT to convey the multi-sensory information such as visual, acoustic, and tactile sense. It
let each visitor feel the stereoscopic images, tactile sense, and touched sound of the "Kaiju-budo-kyo", a mirror with the design of animals,
birds, insects and grapes (important cultural properties), which was unearthed from the "Takamatsuzuka Kofun", an ancient burial mound.
The visitors appeared to be attracted to the virtual experience because they had touched such an important cultural property that could neverbe realized. At the "Let's create clouds! " booth, visitors experienced the joy and wonder of science by creating a small cloud of water vapor.
The pressure built up inside the special container turns water (mouthwash at this time) to steam.
We gratefully acknowledge visitors including junior high school students who volunteered to help us in conducting experiments with appreciation.
