文摘This paper proposes an improved non-repudiation protocol after pointing out two attacks on an existing non-repudiation protocol. To analyze the improved protocol, it also proposes an extension of Kailar logic. Using the extended Kailar logic, the security analysis of the improved prototocol has been presented. Key words non-repudiation protocol - extended Kailar logic - converse assumption procedure CLC number TP 393. 08 Foundation item: Supported by the National Natural Science Foundation of China (90104005) and the Doctoral Science Foundation of Ministry of Education (20020486046)Biography: Li Li(1976-), female, Ph. D candidate, research direction: network security and formal analysis of security protocol.
