：提出安全协议本质上是协议主体利用密码学手段通过挑战一响应来对协议另一方的存在做出判断，并同

时完成对一些数据例如会话密钥等的协商。依据这种思想，结合认证逻辑中的一些成果，提出了一种新的安全协

议关联性的分析方法，该方法对协议认证目标进行了基于线空间模型语义的定义，并将关联性分析归结为Strand

的存在关系和Strand参数一致性的分析问题。-: proposed security agreement on the nature of the agreement is the main means of the use of cryptography through the response to a challenge to the existence of other agreements made judgment and be completed at the same time on some key data such as the oral consultations. Based on this idea and certification of some logical outcome, a new security agreement relevance of the analysis method, The objective of the agreement for the certification based on linear space model semantic definition, Correlation analysis will be reduced to the existence of relations between the Strand and Strand parameters consistency of the problem.
