In reputation systems, how to obtain node's reputation is a crucial issue. To solve this problem, a two-layer reputation search mechanism based on ant colony and grouping is proposed. The first layer is the monitoring platform. According to physical topology, it divides nodes into groups. Each group uses network segment as its identification, and it has a super node and a candidate node. The second layer includes a group management module and an ant colony algorithm. A source node sends its request to the monitoring platform. The latter checks whether the source node and destination node are in the same group. If it is met, the destination node's reputation will be searched in the group with the ant colony algorithm. Otherwise, this algorithm is used to find the super node in the group of the source node firstly. Then the algorithm is used to locate destination group among super nodes. Lastly, the required reputation is obtained. Simulation results show that the proposed mechanism can shorten search distance and search time effectively. 1553-9105/Copyright © 2013 Binary information Press.

An accountable authority attribute-based encryption （A-ABE） scheme is presented in this paper. The notion of accountable authority identity-based encryption （A-IBE） was first introduced by Goyal at Crypto＇07. It is a novel approach to mitigate the （inherent） key escrow problem in identity-based cryptosystems. In this work, the concept of accountable authority to attribute-based encryption （ABE） setting is generalized for the first time, and then a construction is given. The scheme non-trivially integrates an A-IBE scheme proposed by Libert et al. with an ABE scheme. In our construction, a user will be identified by a pair （ id, o~）, where id denotes the user＇ s identity and ω denotes the set of attributes associated to the user. In addition, our construction is shown to be secure under some reasonable assumptions.

This paper proposes the use of ultrasonic microscale subarrayed MIMO RADARs to estimate the position of breast cancer nodes. The transmit and receive antenna arrays are divided into subarrays. In order to increase the signal diversity each subarray is assigned a different waveform from an orthogonal set. High-frequency ultrasonic transducers are used since a breast is considered to be a superficial structure. Closed form expressions for the optimal Neyman-Pearson detector are derived. The combination of the waveform diversity present in the subarrayed deployment and traditional phased-array RADAR techniques provides promising results. © 2014 Attaphongse Taparugssanagorn et al.

Augmented finite transition systems generalize nondeterministic transition systems with additional liveness conditions. We propose efficient algorithms for synthesizing control protocols for augmented finite transition systems to satisfy high-level specifications expressed in a fragment of linear temporal logic (LTL). We then use these algorithms within a framework for switching protocol synthesis for discrete-time dynamical systems, where augmented finite transition systems are used for abstracting the underlying dynamics. We introduce a notion of minimality for abstractions of certain fidelity and show that such minimal abstractions can be exactly computed for switched affine systems. Additionally, based on this framework, we present a procedure for computing digitally implementable switching protocols for continuous-time systems. The effectiveness of the proposed framework is illustrated through two examples of temperature control for buildings.

Software developers are not necessarily security specialists, security patterns provide developers with the knowledge of security specialists. Although security patterns are reusable and include security knowledge, it is possible to inappropriately apply a security pattern or that a properly applied pattern does not mitigate threats and vulnerabilities. Herein we propose a method to validate security pattern applications. Our method provides extended security patterns, which include requirement- and design-level patterns as well as a new model testing process using these patterns. Developers specify the threats and vulnerabilities in the target system during an early stage of development, and then our method validates whether the security patterns are properly applied and assesses whether these vulnerabilities are resolved. © 2013 IEEE.

Reliability is an important software trustworthy attribute. But most existent reliability model don't consider the severity degree of software fault, so traditional software reliability model can't reflect the trustworthiness of software. Based on the analysis of typical J-M reliability growth model, this paper modifies some of the model assumptions and classifies the software faults. Besides, this paper presents a new method based on weight to calculate the degree of software reliability. Finally, according to the different of frequency of software faults, a practical reliability prediction method is proposed and the experiment results shows that the improved model has a better forecast accuracy.

Topic Model is one of the important subfields in Data Mining, which has been developed very quickly and has been applicated in many fields in recent years. Many researchers have been engaged in this field. In this paper, we introduce the BNB process based on Beta and Negative Binomial distribution, using the hierarchical distribution instead of Dirichlet in LDA. And we give the expression of parameter estimation used by Gibbs sampling. Then, BNB process is applicated in the text topic classification. We design experiments to decide the numbers of topics and compare the BNB process with LDA. Experiment results show that the BNB process has better performance over LDA in English Dataset, but they have almost the same result in Chinese micro-blog topic classification. Finally we analyze the problem and give the idea in further research. © (2013) Trans Tech Publications, Switzerland.

Journal of Computational information Systems 2013年第20期9卷 8147-8154页

作者： Zhu, Bohui Ding, Yongsheng Hua, Jing Hao, Kuangrong Hong, Lijuan College of Information Sciences and Technology Donghua University Shanghai 201620 China The Third Research Institute of Ministry of Public Security Shanghai 200031 China Engineering Research Center of Digitized Textile and Fashion Technology Ministry of Education China Department of Computer Science Wayne State University Detroit MI 48202 United States

In this paper, we present a novel approach to detect human base on the fusion of depth and vision information. Instead of conventional human detection method which is mostly done in color image, our approach not only detects human and annotates their position but also extracts whole body pixels from depth image. Our approach has huge advantage over traditional vision image based method, since depth feature is robust against illumination changes, discriminative to background clutter and stable to human pose variation. This system contains a model based human head detector, which detects head through fusion of depth and color haar feature based detector. Then we propose a graph based algorithm to extract whole human body from depth image based head pixels. The experimental results on a large real-world dataset demonstrate that our method has an outstanding performance. © 2013 Binary information Press.

At Crypto'07, Goyal introduced the notion of accountable authority identity-based encryption (A-IBE) in order to mitigate the inherent key escrow problem in identity-based encryption, and proposed two concrete constructions. In an A-IBE system, if the private key generator (PKG) distributes a decryption key or produces an unauthorized decryption box for a user maliciously, it runs the risk of being caught and sued in the court of law with the help of a tracing algorithm. Subsequent efforts focused on constructions of A-IBE schemes with enhanced security. In these A-IBE constructions, the tracing algorithm needs to take a user's decryption key as input. If the user lost his key or is deliberately uncooperative in court, then we cannot implicate the PKG or the user. An interesting open problem left by Goyal et al. at CCS'08 is to consider the possibility of tracing a decryption box using only a public tracing key, or with the assistance of a tracing authority. In this paper, we address this problem positively. We first extend the original model of A-IBE to accommodate public traceability, and then propose an A-IBE scheme in the new model. To the best of our knowledge, the proposed scheme is the first A-IBE with public traceability. © 2013 Springer-Verlag.
