Abstract:
The background of AKE protocol in multiple PKG environments are introduced. Through the analysis of M-B protocol and AKE protocols in multiple PKG environments, it points out their security leak separately. The latter is improved. A new AKE protocol in multiple PKG environments is presented. Heuristic analysis results show that, compared with other protocols, the enhanced protocol holds perfect security property.
Key words:
ID-based,
authenticated key agreement,
bilinear pairing,
multiple PKG environments
摘要: 介绍不同PKG环境下的AKE协议,分别对M-B协议及不同PKG环境下的AKE协议进行安全性分析,并指出其存在的安全缺陷。对后者进行改进,提出一个新的在不同PKG环境下的AKE协议。通过启发式分析证明改进协议可以抵抗已知所有攻击,同时通过与其他相关协议的比较可以发现,改进协议具有更好的安全属性。
