针对串空间理论的不足,在相关研究的基础上,加入了Diffie-Hellman操作的密码原语,扩展了理想和诚实的概念,拓展了串空间理论的分析范围.分析了一个端对端安全协议的核心安全特性,即保密性和认证特性,使用扩展的串空间理论分析得出该协议不能满足认证性,给出该协议的一个攻击和改进方法.
針對串空間理論的不足,在相關研究的基礎上,加入瞭Diffie-Hellman操作的密碼原語,擴展瞭理想和誠實的概唸,拓展瞭串空間理論的分析範圍.分析瞭一箇耑對耑安全協議的覈心安全特性,即保密性和認證特性,使用擴展的串空間理論分析得齣該協議不能滿足認證性,給齣該協議的一箇攻擊和改進方法.

This paper added Diffie-Hellman cryptographic primitives into strand space aim at the weak of the strand space. Extended the honest and ideals concepts of the strand space,which extended the scope of the strand space. Analyzed the core security property of a station to station protocol, confidentiality and authentication. Used the extended strand space to analysis the protocol and deduced this protocol could not meet the authentication property. Descripted an attack and an improvement of this protocol.
