摘要: 基于串空间模型的极小元和理想理论,对网络管理中的一种互认证密码协议进行保密性和认证性分析,通过分析发现该协议存在冗余部分,并提出相应的改进方案;同时在协议的认证性设计方面,指出基于非对称密码系统和对称密码系统的认证协议的区别。

Abstract: Based on the minimal members theory and ideals theory of strand space model, from the authentication and secret aspects, formal analysis is carried on to a mutual-authentication cryptographic protocol which is used in network management , and through the analysis the redundancy which exists in the protocol is discovered and the corresponding improvement is proposed. Meanwhile in the aspect of authentication design to a protocol, the difference is pointed out between the authentication protocols based on the asymmetrical cryptographic system and one based on the symmetrical cryptographic system.
