This paper focuses on the factors that influence the consumers' willingness to buy from an e-commerce vendor. We develop 4 structural equation models (SEM) integrated these factors to test our hypotheses. The result shows that perceived reputation, perceived risk and ease of use are positively associated with the level of consumers' willingness to buy, however, perceived size, perceived system assurance,...
Structured peer-to-peer networks overlay provide a substrate for the contribution of scalability, load balance, decentralization, and availability. However, new nodes are confronted with hijacking attacks on the peer-to-peer overlay with attackers. This paper proposes a model that the malicious nodes can not modify messages over the links and therefore can not control identifiers of correct nodes...
In this article, the security system of WLAN and security measure of WLAN in which IEEE 802.11 series are used as standard of communications is introduced. The defects of security system which is used now are analyzed and the projects for improving the security system which is used now are put forward.
In this paper, we propose a scalable RSA cryptosystem chip, which is implemented with a 32-bit modular multiplier. Our design provides the trade-off between security and computation time. If the security is more important, we can choose longer key to get higher security. Otherwise, the shorter key could be chosen to reduce the computation time. The RSA core takes 2.83 M clocks to finish a 512-bit...
In mobile ad hoc networks nodes should collaborate with each other to support the functions of the network. The trust management framework, which evaluates the trust of participating nodes, is used to force nodes to cooperate in a normal way. We make an effort to design a robust and attack-resistant trust management framework for the future. In this article we describe the vulnerabilities of and possible...
