NS公钥认证协议的另一个改进方法

Another Modification of NS Public-key Authentication Protocol

将NS公钥认证协议解析为两个质询-应答型的单向认证子协议,并从消息方向标识缺失的角度对协议的设计缺陷进行了分析,在该基础上提出了针对NS公钥认证协议的另一种改进方法。

The analyzing methods are to parse NS public-key authentication protocol into two one-way authentication sub-protocols of challenge-response type and to analyze its design flaw from the view of the direction identifier loss of the message. Based on the above ways, another kind of modified version of this protocol is offered.
