摘要
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.
