Needham-Schroeder协议的认证测试方法形式化分析

Formal analysis of Needham-Schroeder protocol with authentication test methods

在安全协议的形式化分析方法中,串空间模型和基于串空间模型的认证测试方法是比较常用的验证方法。针对Need-ham-Schroeder协议存在中间人攻击的缺陷,提出对协议的改进并采用认证测试方法,验证了改进的协议可以满足协议的安全目标。

Among the formalized analysis methods of security protocol,the strand space model and the authentication test methods based on the strand space model are the commonly used methods.For the defects of man-in-middle attack in the Needham-Schroeder protocol,the paper gives the improvements and adopts the authentication test methods to verify the improved Needham-Schroeder protocol can meet the demands of security goals of protocol.
