摘 要: | 认证邮件协议需要满足保密性、公平性、可追究性等安全属性。针对一个典型的认证邮件协议在保密性、可追究性上存在的安全缺陷,对其进行了改进,提出了一个基于离线半可信第三方的认证邮件协议。同时,为更有效地分析协议的安全属性,对如何在组合协议分析框架下应用Kailar逻辑分析公平交换协议安全属性的方法进行了研究。利用该方法分析了改进后的协议,并证明了该协议具有满足保密性、可追究性等安全属性的特点。

Abstract: | The security attributes of certified e-mail protocol include confidentiality, non-repudiation, fairness. Aiming at to remedy the lack of confidentiality and non-repudiation of the a typical certified mail protocol, an improved certified mail protocol with transparent semi-trusted third party is proposed. To improve the protocol efficiency, a method applying Kailar logic in compositional analysis is proposed for analyzing the improved protocol. The analysis results indicate the improved protocol can meet confidentiality and non-repudiation. |
