缺乏固定的基础设施，物理和组织，以及高度动态的性质，特设无线网络的安全机制的定义，这样的网络提出了重大的困难。在这种无脊椎网络中的密钥管理是研究这种网络的安全服务的关键领域。传统的密钥管理解决方案需要一个固定的基础设施或集中式服务，既不适合也没有效率的使用在ad hoc网络。本文提出了一种基于椭圆曲线密码系统的完全分布式认证密钥协商协议。所提出的协议允许授权的组成员生成他们的会话密钥，而不需要一个可信的第三方。该协议还提出了一个修改，以提高协议的效率，使用组聚类技术。
The lack of fixed infrastructure, both physical and organizational, and the highly dynamic nature of ad hoc wireless networks present major difficulties in the definition of the security mechanisms for such networks. The management of cryptographic keys in such spineless networks is a key area of research into security services of such networks. Traditional key management solutions that require a fixed infrastructure or centralized services are neither suited nor efficient for use in ad hoc networks. In this paper, we propose a fully distributed authenticated key agreement protocol based on the use of elliptic curve cryptosystems. The proposed protocol allows authorized group members to generate their session key without the need for a trusted third party. A modification of this protocol is also proposed to improve the protocol efficiency using a group clustering technique.
