Furthermore, we give some theoretical analysis of our rules using the strand spaceformalism, and show the soundness of our idealization rules under strand spaces Some examples onusing the new rules to analyze security protocols are also concerned. Our idealization method ismore effective than Mao's method towards many protocol instances, and is supported by a formalmodel.展开更多

Using Protocol Composition Logic (PCL),this paper proves a Mobile IP (MIP) registration protocol that is based on certificateless public key signature without pairing between home agent and foreign agent,which minimizes the registration time and cost as well as improves the security compared with the identity-based and certificate-based registration protocol. Analysis and proof shows that the proposed protocol provides users security and authentications,moreover,the anonymity property is proved correct.展开更多

Recently, many routing protocols have been proposed attempting to find suitable routes to transmit data. In this paper we propose a Fuzzy Energy Aware tree-based Routing (FEAR) protocol that aims to enhance existing tree-based routing protocols and prolong the network’s life time by considering sensors’ limited energy. The design and implementation of the new protocol is based on cross-layer structure where information from different layers are utilized to achieve the best power saving. Each node maintains a list of its neighbors in order to use neighbors’links in addition to the parent-child links. The protocol is tested and compared with other tree-based protocols and the simulation results show that FEAR protocol is more energy-efficient than comparable protocols. According to the results FEAR protocol saves up to 70.5% in the number of generated control messages and up to 55.08% in the consumed power.展开更多

Fairness of such protocols in literature highly depends on an additional TTP（trusted third party）. However, it is difficult to find such a TTP in some situations. In addition, fairness for customers has been neither fully considered nor well satisfied in existing electronic purchasing protocols. In this paper, a new protocol FEP （fair electronic purchase） without a special TTP but an online bank is presented based on a concurrent digital signature scheme. The FEP protocol guarantees fair electronic purchase of goods via electronic payment between consumers, merchants and their online banks. The protocol is practical and the analysis based on the game logics shows that it achieves the properties of viability, fairness, and timeliness.展开更多
