摘要： 以节点的公钥证书为基础，基于椭圆曲线密码体制提出一种分簇结构的Ad Hoc网络会话密钥协商协议，对协议的安全性和效率进行分析。该协议满足普遍认可的密钥协商安全要求，可抵抗中间人攻击、重放攻击、消息伪造攻击等多种攻击，有效地降低终端的计算、存储能力需求，减少了协商过程的通信开销。

Abstract: Based on the nodes’ public key certificates, this paper proposes a clustering-based session key agreement protocol in Ad Hoc networks using the Elliptic Curve Cryptography(ECC). It analyzes the security and efficiency of the protocol. The protocol satisfies the common admissive security demands in key agreement. It can resist the man-in-the-middle attack, replay attack, message forge attack and so on, the requirement of computation and storage in mobile terminal is reduced, and the communication burden in the process is lessened effectively.

Key words: Ad Hoc network, Elliptic Curve Cryptography(ECC), clustering, key agreement
