Now, autonomous tasks planning and allocating (TPA) in Multi Agent System (MAS) has been one key and fundamental problem to promote the intelligent level of such system. Autonomous TPA means that, all tasks should be (re)planned and (re)allocated automatically according to the synthesis constraints and the dynamic environment aspects, such as the changing mission, status of each member, and topology, etc. In this article, the formal descriptions of hierarchical tasks and models of logic constraints are studied firstly. And then, some new methods are proposed to evaluate the efficiency of synthesis constraints. Moreover, the key elements, e.g. task allocation vector (TAV), are designed with the theory of genetic algorithm (GA), and a TPA problem can be mapped to the solving model of GA. Based on above, the crossover and mutation operators of GA are optimized with the domain knowledge to perfect the solving efficiency and quality while ensuring the randomicity of evolution. The simulation results show that the solving quality and velocity are improved with studied methods. © 2009 IEEE.

Leveled Group key Management with Efficient Revocations for Wireless Sensor networks

电子学报(英文版) 2009年第3期18卷 494-499页

作者： LI Fenghua YAN Junzhi MA Jianfeng WANG Wei Key Laboratory of Computer Networks and Information Security (Ministry of Education) Xidian University Xi＇an 710071 China Graduate School Beijing Electronic Science and Technology Institute Beijing 100070 China No.36 Research Institute of CETC Jiaxing 314033 China

Wireless sensor networks are often deployed in hostile environments. Protecting the communication against node capture is one of the most important design objectives. Focused on the revocations of resource constrained nodes, an efficient leveled group key management scheme is proposed. This scheme is based on a novel application of an a-ary logical key tree. Since sensor nodes may leave or join the WSN frequently, a sublevel session key is introduced to protect the sensitive information transmitted in the network. In a leave event, the rlegal sensors in the key tree are partitioned into disjointed subtrees. The group key can be updated securely by encrypting the new group key with the common keys shared by the sensors in the same subtree. When a sensor requests to join the communication group, it is assigned a sublevel session key which is used to communicate with GCKS and other legal sensors. The current session key is sent to the new sensor only after it gets the trust of GCKS. This scheme is scalable, stateless and simple to employ.

Extending Weight-Balanced key Tree without Adjustment-Propagation

电子学报(英文版) 2009年第1期18卷 79-83页

作者： WANG Wei ZHAO Wenhong LI Fenghua MA Jianfeng No. 36 Research Institute of CETC Jiaxing 314033 China Key Laboratory of Computer Networks and Information Security (Ministry of Education) Xidian University Xi＇an 710071 China Graduate School Beijing Electronic Science and Technology Institute Beijing 100070 China

An Extending weight-balanced tree (EWB tree) for group key managements is presented. By introducing a special path in the weight-balanced key tree, the EWB tree does not cause adjustment-propagation after member adding or member deleting. The bounds ratio of the EWB tree based algorithm to that of the optimal tree shows that the bounds of EWB tree is better than those of the height-balanced 2–3 tree and equal to those of the weight-balanced 2–3 tree. The analysis also shows that the proposed scheme has fewer rekeying cost than the ones based on the weight-balanced 2–3 tree, height-balanced 2–3 tree, LTM tree and NSBHO tree.

Silicon nitride microring resonators were demonstrated as chemical sensors. The microring devices,with diameter of 100 μm, were fabricated using complementary metal oxide semiconductor（CMOS）-compatible technology, and a high Q factor of 15000 was realized with free spectrum range（FSR） of 2 nm. The structures were further packaged to perform as chemical sensors, and their functionality was proved using deionized water（DI water）and ethanol as detecting mediums. Lastly, the packaged chips were used to detect glucose solutions with various concentrations, and a detection capability of refractive index change of 10–3refractive index unit（RIU） was obtained.

Secure and efficient VSS scheme based on partial broadcast channels

Journal of Computational Information Systems 2009年第3期5卷 1149-1155页

In the conventional verifiable secret sharing scheme, a dealer uses point-to-point secure channels to distribute the shares of a secret to a number of participants. Rei and Wang proposed a secret sharing scheme based on partial broadcast channels, which reduced the number of the channels. But it supposed that both the dealer and participants were honest. In this paper, we present a secure and efficient verifiable secret sharing (VSS) scheme based on partial broadcast channels, which solves the problem in Rei and Wang's scheme. Through the analysis of the scheme, we get that it is secure and efficient, and has the advantage of the number of channels and the total communications needed compared with the conventional verifiable secret sharing scheme. 1553-9105/ Copyright © 2009 Binary Information Press.

This paper explores protein-protein interaction extraction from biomedical literature using support vector machines (SVM). Besides common lexical features, various overlap features and base phrase chunking information are used to improve the performance. Evaluation on the AIMed corpus shows that our feature-based method achieves very encouraging performances of 68.6 and 51.0 in F-measure with 10-fold pair-wise cross-validation and 10-fold document-wise cross-validation respectively, which are comparable with other state-of-the-art feature-based methods.

Fabrication of microscale and nanoscale silicon waveguide devices requires patterning silicon, but until recently, exploitation of the technology has been restricted by the difficulty of forming ever-small features with minimum linewidth fluctuation. A technique was developed for fabricating such devices achieving vertical sidewall profile, smooth sidewall roughness of less than10 nm, and fine features of 40 nm. Subsequently, silicon microring resonator and silicon-grating coupler were realized using this technique.

Democratic Group Signatures with Threshold Traceability

Journal of Shanghai Jiaotong university(science) 2009年第1期14卷 98-101页

This paper presents a concrete democratic group signature scheme which holds （t, n）-threshold traceability. In the scheme, the capability of tracing the actual signer is distributed among n group members. It gives a valid democratic group signature such that any subset with more than t members can jointly reconstruct a secret and reveal the identity of the signer. Any active adversary cannot do this even if he can corrupt up to t - 1 group members.

An access control policy defines what is authorized, and an access control mechanism implements the policy to ensure that all accesses are in accordance with the underlying policy. Nowadays, many researcher are working for expressing access policies in a formal way. But it is still an open problem. This paper defines a policy language, which is named as PDPL to express access policies and access control properties in PDAC model [1]. This language unifies ldquoBANrdquo logic with past- and future- time temporal logic. We give the syntax and semantics of PDPL, and provided some examples with their English equivalents. This logic language can express belief and authorization in access control model. And it can deal with delegations of decision-making directly. It is easy for us to formulate the properties of interest in distributed systems of PDAC model through PDPL. This logical language is part of a formal system, and it will be used in an automatic model checker in the future.
