身份认证协议的新安全属性

NEW SECURITY NOTIONS IN IDENTITY AUTHENTICATION PROTOCOL

总结了针对身份认证协议的一类新型攻击的特征。对于攻击的分析,引入了两个新的安全属性定义,其一定义在单个证明者的环境中,另一个则定义在多个证明者的环境中。并可证明这两个安全属性本质上是等价的。因此,只要满足了其中单证明者环境下的安全要求,身份认证协议也能安全地运行在多个证明者的环境下。

In this paper two novel security notions were defined according to the analysis of the summarized features of a new kind attack against the identity authentication protocol. Though one notion was defined in single prover condition and the other was in multi-provers condition hut they were proved to he equivalent in essence. Therefore once the security requirement in single prover condition is satisfied the identity tuthentication protocol can also he run in multi-provers condition.
