摘要: 认证密钥协商协议是一种重要的密码学原语。该文分析一种基于身份的认证密钥协商协议,并在Bellare-Rogaway-93模型下进行安全证明。在允许攻击者进行Reveal询问时,指出该协议的不安全性。研究结果发现,该协议不能抵抗密钥泄露伪装攻击。

Abstract: Authenticated key agreement is an important original language of cryptology. This paper analyzes an ID-based authenticated key agreement protocol, carries a proof of security in the Bellare-Rogaway-93 model, pointes out the protocol is insecure if the adversary is allowed to send a Reveal query. Researches show that the protocol can not resist the key compromise impersonation attack.

Key words: cryptanalysis, ID-based authenticated key agreement, key compromise impersonation attack
