The 1st chinese Conference on Trusted Computing and information {2.

作者： LING He-fei, LU Zheng-ding, ZOU Fu-hao College of Computer Science and Technology, Huazhong university of Science and Technology, Wuhan 43.074, Hubei, china

＜正＞ In order to improve the robustness of the differential number watermarking （DNW） algorithm proposed by us before, we proposed turbo-based DNW （T-DNW） in which the turbo code was employed in the DNW algorithm. The turbo code was used to encode the message prior to watermark embedding and decode the watermark posterior to watermark detection. From the analysis and experiments, the following conclusion could be drawn. The T-DNW algorithm has little higher computational complexity than DNW. And both algorithms have the same performance in terms of watermark visual quality impact. Furthermore, the T-DNW algorithm is much more robust against some common attack than DNW. Although the T-DNW algorithm sacrifices a half pay-load, we think the achievements are encouraging.

＜正＞ We mainly explore two problems when combining IPSec module into TCP/IP stack by porting the famous IPSec software （FreeS/WAN ） into a security gateway. One is how to implement the IPSec module based on Netfilter in Linux 2. 4. x kernel. The other problem is the performance evaluation. We test the throughput of our security gateway before and after applying IPSec with different encryption/decryption algorithms, including the software-based and hardware-based method. With these testing data, we analyze further system performance bottleneck. In the end. we also infer the quantitative relation between the system throughput and the speed of encryption/decryption algorithm and propose some valuable conclusions for improving performance.

＜正＞ Threshold blind signature is playing an importantrole in cryptography as well as in practical applications such as e-cash and e-voting systems, etc. In this paper, we present an efficient and practical threshold bind signature from Weil pairing on super-singular elliptic curves or hyper-ellipti（?） curves over finite field and prove that our scheme is provably secure in the random oracle model.

An In-Depth Study of Complex Power System Dynamic Behavior Characteristics for chinese UHV Power Grid security

引用

Electricity 2009年第2期20卷 45-51页

作者： Ding Daoqi State Grid information & Telecommunication Co.,Ltd.Zhao Fang State Grid information & Lelecommunication Co.Ltd

In this paper,a series of major policy decisions used to improve the power grid reliability,reduce the risk and losses of major power outages,and realize the modernization of 2.st century power grid are discussed. These decisions were adopted by American government and would also be helpful for the strategic development of chinese power grid. It is proposed that china should take precaution,carry out {2. research on the overall dynamic behaviour characteristics of the UHV grid using the complexity theory,and finally provide safeguard for the chinese UHV grid. It is also pointed out that,due to the lack of matured approaches to controll a cascading failure,the primary duty of a system operator is to work as a "watchdog" for the grid operation {2.,eliminate the cumulative effect and reduce the risk and losses of major cascading outages with the help of EMS and WAMS.

意识形态是上层建筑的重要组成部分,代表一定阶级、群体的利益,在维护政权稳定、维系社会安定方面发挥重要作用。思想政治教育本身不是意识形态但与意识形态关系密切,二者在本质上具有一致性、在内容上具有交互性、在作用上具有同一性。随着全球化的冲击、大数据时代的到来,价值取向多元化、信息传播多样化,既为社会主义意识形态的传播创造了机遇,也埋下意识形态安全的隐患,这就需要充分发挥高校思想政治教育在意识形态领域中的传声筒、防护网、调和器以及催化剂的作用,提高高校思想政治教育的实效性,推进马克思主义中国化时代化大众化,推进建设具有强大凝聚力和引领力的社会主义意识形态。

Polynomial Analysis of DH Secrete Key and Bit security

Polynomial Analysis of DH Secrete Key and Bit Security

The 1st chinese Conference on Trusted Computing and information {2.

作者： JIANG Zheng-tao. XU Wen-li, WANG Yu-min National Key Laboratory of Integrated Service Networks Xidian university, Xi''an 710071, Shaanxi, china

＜正＞ In this paper, we lower the upper bound of the number of solutions of oracle transformation polynomial F（x） over GF（q）. So one can also recover all the secrete keys with fewer calls. We use our generalized " even-and-odd test" method to recover the least significant p-adic ’bits’ of representationsof the Lucas Cryptosystem secret keys x. Finally, we analyze the Efficient Compact Subgroup Trace Representation（XTR） Diffie-Hellmen secrete keys and point out that if the order of XTR-subgroup has a special form then all the bits of the secrete key of XTR can be recovered form any bit of the exponent x.

作者： WANG Lun-wei. LIAO Xiang-ke. WANG Huai-min School of Computer Science, National university of Defense Technology , Changsha 410073. Hunan, china

＜正＞ Weighted factor is given to access control policies to express the importance of policy and its effect on access control decision. According to this weighted access control framework, a trustworthiness model for access request is also given. In this model, we give the measure of trustworthiness factor to access request, by using some idea of uncertainty reasoning of expert system, present and prove the parallel propagation formula of request trustworthiness factor among multiple policies, and get the final trustworthiness factor to decide whether authorizing. In this model, authorization decision is given according to the calculation of request trustworthiness factor, which is more understandable, more suitable for real requirement and more powerful for security enhancement than traditional methods. Meanwhile the finer access control granularity is another advantage.

Real-time streaming media transmission has been used widely in the network monitoring system, and audio- video synchronization is a key issue. Since the use of RTP protocol in data transmission, the synchronization problems can be simplified greatly if the time information in RTP data packets is used effectively. Based on the experience in the Network monitoring system programming, this monitoring system makes full use of the timestamp in the RTP protocol, expounds how to set reference time and the timestamp and how to program the audio-video synchronization.

＜正＞ In this paper, we point out that Libert and Quisquater’s signeryption scheme cannot provide public *** we present a new identity based signcryption scheme using quadratic residue and pairings over elliptic curves. It combines the functionalities of both public verifiabilityand forward security at the same time. Under the BilinearDiffie-Hellman and quadratic residue assumption, we describe the new scheme that is more secure and can be somewhatmore efficient than Libert and Quisquater’s one.
