| 摘 要： | LaM acchia等提出了扩展的Canetti-K raw czyk(eCK)安全模型,该模型涵盖了认证密钥协商协议的所有安全特性.鉴于目前大多数基于身份的认证密钥协商协议在eCK模型中是不安全的,利用椭圆曲线加法群构造了一个eCK模型中安全的基于身份认证密钥协商协议.和其它的协议相比,新协议的计算复杂度和通信复杂度较低.新协议提供强安全性,它的安全性证明依赖于随机预言假设和GBDH假设.

| Abstract: | Recently,LaMacchia et al.proposed the extended Canetti-Krawczyk(eCK) model,which captures all security properties of authenticated key enchange protocols.Most of existing identity-based authenticated key exchange protocols are not secure in the eCK model.This paper proposes an identity-based authenticated key exchange protocol,and the security of proposed protocol can be proved in the eCK model.When compaer with other schemes,the proposed protocol achieves efficiency in terms of computation and communicatio... |
