摘要
基于身份的认证密钥协商(ID-AKA)协议大多效率低下、安全性较低。针对该问题,提出一个新的ID-AKA协议。利用模块化的方法证明新协议在mBR模型满足抗密钥泄露模仿攻击、完美前向安全性以及PKG-前向安全性。新协议还满足抗临时秘密泄露攻击。与同安全级别的协议相比,新协议的效率更高。
Most Identity-based Authenticated Key Agreement(ID-AKA) protocols have poor performance on security and the efficiency. To solve this problem, this paper presents an improved ID-AKA protocol. Security proof with the modular approach in the mBR model is provided, which means the new protocol satisfies perfect forward security, PKG forward security, resistant to key-compromise impersonation. Furthermore, the new protocol can satisfy resistance to leakage of ephemeral secrets. Compared with previous ID-AKA protocols which can satisfy the same security properties, the new protocol has higher efficiency.
