摘要
根据安全协议分析的需要,阐述经扩展后的串空间理论,在该理论中加入Diffie-Hellman密钥交换等操作,在此基础上扩展理想和诚实的概念,使用扩展的串空间理论分析SIGMA-R协议的核心安全特性——保密性和认证特性,并通过数学方法加以验证。
Due to the requirement of the security protocol analysis, the paper presents the extended strand space theory. A new cryptographic primitive is added into strand space including Diffie-Hellman(DH) operations. On this basis, the honest and ideals concepts are extended. The core security property of the SIGMA-R protocol, confidentiality and authentication, is analyzed by using the extended strand space theory. Through the mathematic method, the two security properties are identified.
