Ad hoc网络中一种基于身份的组密钥协商协议

移动Ad hoc网络是一种资源有限的移动多跳无线网络。在网络中构建组密钥协商协议时应尽可能地减少资源开销。文中在基于身份的网络安全环境下，设计了一种基于环状结构的组密钥协商协议。该协议采用椭圆曲线上的双线性配对，仅通过单轮通信完成组密钥协商。经过分析，该协议具有等献性，已知密钥安全，无密钥控制等安全属性，适用于Ad hoc网络。

ID-Based Group Key Agreement Protocol for Ad Hoc Networks

Amobile ad hoc network is aresource-limited mobile multihop wireless network. So the resource overhead should he minimized when constructing the group key agreement protocol in the ad boa network. This paper proposes a group key agreement protocol based on a circular structure under ID-based Public Key Infrastructure. In this protocol, bilinear pairing on the elliptic curve is employed, and the group key could be established only in one round communication. The analysis indicates that this protocol has many security attributes such as equal contribution, known-key security, non key control, etc and is suitable to Ad hoc networks.
