Chinese Physics Letters 2009年第12期26卷 35-38页

作者：林崧温巧燕刘晓芬 Key Lab of Network Security and Cryptography Fujian Normal University Fuzhou 350007 State Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications Beijing 100876

In a recent paper [Yan F L et al. ***. 25（2008）1187], a quantum secret sharing the protocol between multiparty and multiparty with single photons and unitary transformations was presented. We analyze the security of the protocol and find that a dishonest participant can eavesdrop the key by using a special attack. Finally, we give a description of this strategy and put forward an improved version of this protocol which can stand against this kind of attack.

In a recent paper [C.H. Hong et al., Opt. Commun. 283 (2010) 2644], a n-user quantum key distribution protocol with n quantum channels was presented. By analyzing its security, it is shown that this protocol is insecure for Trent, a dishonest third party, who can steal the key without being detected by a special attack strategy. We give a description of this strategy and then put forward an improved protocol, which can stand against this attack. Furthermore, the improved protocol is feasible in the current technology conditions, because it is just required an incomplete Bell-state measurement in implementation of it. © the authors.

作者： Chen, Zhide Wang, Meng Xu, Li Wu, Wei Key Lab of Network Security and Cryptography School of Mathematics and Computer Science Fujian Normal University Fujian Province Fuzhou China

With the popularity of mobile smart devices and functional diversification, the infection ways of mobile smartphones worm also become diverse. In mobile networks, mobile devices are suffering from the threat of worms all the time. Once the worm outbreaks, it will bring huge losses to mobile phone users and mobile network operators. Researches on mobile worm propagation model allow us to control and detect potential worm threat, according to the characteristics of worm's outbreak. In the paper, we put forward a worm propagation model based on the mobile network environment. After analyzing the model, we then give the simulation for controlling factors affecting worm propagation. This model allows us to have a certain understanding for the spread on the size and speed of the mobile worm and provide effective methods to control the spread of the mobile worm.

Service price discrimination in wireless network

Service price discrimination in wireless network

International Conference on Computational Science and Engineering

This paper discusses the price discrimination in wireless service allocation on the basis of game theory. The wireless service providers can supply the service with different prices. Two service price discrimination models are proposed. The first one is one wireless service provider with n types of wireless users. Each type has different preference parameter. The wireless users are proved to be individual rational and incentive compatible. The optimal quantity of the service and the optimal price for each type of wireless users are computed to maximize the utility of the wireless service provider. The second model is n service providers with k different prices. The optimal quantity of the service and the optimal prices are computed to maximize the utility of the wireless service provider. © 2010 IEEE.

Optimization of key Predistribution Protocol Based on Supernetworks Theory in Heterogeneous WSN

Tsinghua Science and Technology 2016年第3期21卷 333-343页

This work develops an equilibrium model for finding the optimal distribution strategy to maximize performance of key predistribution protocols in terms of cost, resilience, connectivity, and lifetime. As an essential attribute of wireless sensor networks, heterogeneity and its impacts on random key predistribution protocols are first discussed. Using supernetworks theory, the optimal node deployment model is proposed and illustrated. In order to find the equilibrium performance of our model, all optimal performance functions are changed into variational inequalities so that this optimization problem can be solved. A small-scale example is presented to illustrate the applicability of our model.

Quantum anonymous ranking based on the Chinese remainder theorem

引用

Physical Review A 2016年第1期93卷 012318-012318页

作者： Song Lin Gong-De Guo Feng Huang Xiao-Fen Liu and Key Lab of Network Security and Cryptography Fujian Normal University Fuzhou 350007 China

In this paper, an efficient quantum anonymous ranking protocol with single particles is proposed. A semitrusted server is introduced to help multiple users achieve this secure task. At the end of the protocol, each user can obtain the rankings of his private data, and keep these data secret. The Chinese remainder theorem is utilized to reduce the level of signal particles and to improve the efficiency of the presented protocol. Meanwhile, a secret transmission order of the signal particles is used to keep the traveling particles secure. Finally, we discuss the security of this protocol and prove it to be secure against certain common attacks under ideal conditions.

A novel method, multiple classifier behavior-based data reduction and classification algorithm, called DRC, is proposed in this paper. It arrived at the transformation of the data-space by suing of the multiple classifier behavior vector so that data-sets transform from the original spaces to the behavior spaces. It aims to find some more meaningful representatives to replace the original dataset via classifier behavior vector for further classification. Each representative is formed by its multiple classifier behavior and its neighborhood which satisfies a predefined threshold. Inspired by the spirits of data reduction and classifier selection methods, the proposed DRC not only reduces the cost but also uses the advantage of each single classifier to improve the classification accuracy to a certain extent. This is proved by real world applications such as toxicity prediction of chemical compounds in predictive toxicology.
