In current version of Trusted Network Connection (TNC) architecture, IF-MAP protocol creates a structured way to support real-time data interchange and dynamic management. However, there is a big challenge that the MAP Server has to process mass metadata published by all kinds of other security components in trusted network. In this paper, we propose a novel design for MAP (Metadata Access Point) Sever based on information fusion. A module called HLIF (High level information fusion) is implanted to the current MAP Server. The HLIF module correlates metadata and projects threats in the trusted network to ensure the MAP Clients can share real-time information efficiently and make precise policy decisions in anticipation. Detailed analysis reveals that HLIF module effectively enhances the MAP Server's ability of protecting security components from network attacks in trusted network. © 2010 IEEE.

The proliferation of Internet of Things (IoT) devices and edge computing applications has heightened the demand for efficient resource allocation and pricing mechanisms. Effective pricing strategies play a crucial role in optimizing resource utilization, reducing latency, and ensuring fair resource distribution among users. Both auction theory and game theory have emerged as fundamental economic frameworks for designing pricing mechanisms in edge computing. This paper presents a comprehensive survey of pricing strategies that leverage both auction and game theory, systematically categorizing existing research based on auction mechanisms and game-theoretic models. Unlike previous surveys that focus solely on auction-based pricing, this work integrates game-theoretic perspectives, providing a holistic analysis of strategic interactions in edge computing resource allocation. Furthermore, we discuss key challenges, emerging trends, and future research directions aimed at enhancing efficiency, fairness, and privacy protection in cloud-edge collab.rative computing environments. © 2014 IEEE.

The Programming language for symmetric cryptographic algorithms (PLSCA) is proposed. The detailed specification of the syntax of PLSCA is presented, and the cipher of IDEA is described using PLSCA as an example. Using PLSCA, the cryptography designers could describe the structure of symmetric cryptographic algorithms in a formal way, exchange their ideas and algorithm details, test and analyze the symmetric cryptographic algorithms conveniently and rapidly. PLSCA may improve the testing efficiency of new algorithms. It is adapt to assist the design and automatic analysis for symmetric cryptographic algorithms, and it may be used as a standard language to submit new algorithms to the evaluation staff.

Secure proxy signature scheme with fast revocation in the standard model

Proxy signature is an important cryptographic primitive and has been suggested in numerous applications, Tne revocation oI delegated rights is an essential issue of the proxy signature schemes. In this article, a security model of proxy signature schemes with fast revocation is formalized. Under the formal security framework, a proxy signature scheme with fast revocation based on bilinear pairings is proposed. A security mediator （SEM）, which is an on-line partially trusted server, is introduced to examine whether a proxy signer signs according to the warrant or he/she exists in the revocation list. Moreover, the proxy signer must cooperate with the SEM to generate a valid proxy signature, thus the proposed scheme has the property of fast revocation. The proposed scheme is provably secure based on the computational Diffie-Hellman （CDH） intractability assumption without relying on the random oracles, and satisfies all the security requirements for a secure proxy signature.

Improved Impossible Differential Cryptanalysis of AES-128

Recently, several impossible differential attacks on the Advanced encryption standard (AES) were presented. The previous work is extended by presenting a new impossible differential attack on the AES-128 (with 128 bit secret key) reduced to 7 rounds. Moreover, our result shows that impossible differential attack on the AES-128 reduced to 7 rounds requires 2 ^115.5 chosen plaintexts, 273 memory, and 2¹⁰⁵ seven-round AES-128 encryptions, and works by exploiting weakness in the AES key schedule.

SONICUMOS: An Enhanced Active Face Liveness Detection System via Ultrasonic and Video Signals

SONICUMOS is an enhanced behavior-based face liveness detection system that combines ultrasonic and video signals to sense the 3D head gestures. As face authentication becomes increasingly prevalent, the need for a reliable liveness detection system is paramount. Traditional behavior-based liveness detection methods (e.g., eye-blinking, nodding, etc.), which are widely deployed in mission-critical scenarios like finance and banking applications today, are prone to advanced media-based facial forgery attacks. SONICUMOS aims to incorporate the traditional behaviorbased method for active liveness detection without introducing extra user burden. By employing ultrasonic signals, SONICUMOS capitalizes on the head gestures, significantly raising the security bar. Our approach utilizes the frequency-modulated continuouswave (FMCW) ultrasonic radar for robust 3D gesture recognition compatible with face authentication. We also propose a new dual-feature fusion network that integrates audio and video features at the feature level to increase detection accuracy and resilience against numerous attacks. Our prototype has been tested on seven off-the-shelf Android/iOS smartphones, achieving an overall detection accuracy of 95.83% at an equal error rate (EER) of 4.96% when dealing with 3D impersonation attacks © 2025 IEEE.

Linear complexity of sequences produced by single cycle T-function

The Journal of China Universities of Posts and Telecommunications 2011年第4期18卷 123-128页

作者： WANG Yan HU Yu-pu LI Shun-bo YANG Yang Key Laboratory of Computer Networks and Information Security Ministry of Education Xidian University Xi'an 710071 China Department of Mathematics Xi'an University of Architecture and Technology Xi'an 710055 China

Four kinds of sequences generated by single cycle triangular function （T-function） are investigated to check the possibility for a single cycle T-function to be a cryptographic component in stream ciphers. Based on the special properties of single cycle T-function and an algorithm due to Wei, linear complexities of these four kinds of sequence are all acquired. The results show that single cycle T-function sequences have high linear complexity. Therefore, T-function satisfies the essential requirements being a basic component of stream cipher.

A link analysis model for passive UHF RFID system in LOS indoor environment is developed and demonstrated. Using this model, the power received by tag and the read performance are investigated. The multipath fading and RMS delay spread for UHF RFID system are analyzed by a 5-ray model with different polarization, e.g., horizontal polarization, vertical polarization, and circular polarization. A practical test is developed on an indoor balcony of an office building. In addition, the electric field environment is simulated using the tool of Ansoft HFSS for the analysis of multipath degradation. The results of theoretical analysis, simulation and test are almost conformable, and the small scale fading and the field nulls are observed. Multipath degradation affects the UHF RFID system so much on read performance, and it is still a key limitation on system performance. More research on anti-multipath interference should be developed, e.g., high gain antenna, high sensitivity tag and reader receiver, and more effective protocols, and so on. © 2008 IEEE.
