Abstract: OpenID Connect protocol is widely used in identity authentication field and is one of the newest single sign-on protocols. In this paper, the digital signature and asymmetric encryption were used to improve OpenID connect protocol. The secrecy and authentication of the improved protocol were focused. And then the improved OpenID connect protocol was formalized with the applied PI calculus in the symbolic model, next the secrecy was modeled by query and the authentication was modeled by non-injective relations to test the secrecy and authentication of improved OpenID Connect protocol. Finally the formal model of the OpenID Connect protocol was transformed into the input of the automatic tool ProVerif based on symbol model. The results indicate that the improved OpenID Connect protocol is authenticable and secret.

Key words: aasymmetric encryption, digital signature, authentication, symbol model, formal method, ProVerif

摘要: OpenID Connect协议是最新的单点登录协议之一,已经广泛应用于用户身份认证领域,其安全性受到了人们的重点关注。为增强OpenID Connect协议的安全性,首先引入数字签名及非对称加密技术,对其进行改进,重点关注改进后协议的秘密性和认证性;其次基于符号模型,应用应用PI演算对改进的OpenID Connect协议进行形式化建模;然后为验证改进后协议的认证性和秘密性,分别使用非单射性和query对认证性和秘密性进行建模;最后把改进的OpenID Connect协议的应用PI演算模型转换为安全协议分析工具ProVerif的输入,应用ProVerif对其进行形式化分析。实验结果表明,改进后的OpenID Connect协议具有认证性和秘密性。
