Example Embodiment
[0049] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings: this embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation and specific operation procedures are given, but the protection scope of the present invention is not limited to the following Examples.
[0050] RMNeedham et al. published "Using Encryption for Authenticationin Large Network of Computers" in "Communication of the ACM" (1978, Vol. 21, No. 12, pp. 993-999). The Needham-Schroeder public key authentication cryptographic protocol (hereinafter referred to as the NS protocol) is proposed in Using encryption for authentication. The NS protocol is the basis of a large number of industrial application authentication key protocols. Take the N-S protocol as an example to illustrate the present invention—a cryptographic protocol security detection method based on freshness verification condi...
