Abstract: Combining certificateless signcryption protocol and hierarchical structure,a new key management agreement is proposed.In this scheme,public key certificates are not needed and every participant makes a public key himself.It greatly decreases the need of the ability for computation and storage of terminals,as well as communication cost for system key management.At the same time,the key generator center creates partial private keys for nodes,and then solves the key escrow problem in the identity-based cryptography.Nodes are divided into several autonomous communities based on cluster structure,which not only increases availability and scalability of networks,but also results in quick response to some emergency.

摘要: 结合无证书签密协议,提出一种分级移动Ad hoc网络密钥管理方案。该方案不需要公钥证书,用户自己生成公钥,有效地降低了用户终端计算、存储能力的需求和系统密钥管理的通信开销;同时密钥生成中心为用户生成部分私钥,解决了基于身份密码体制中的密钥托管问题;分级的结构将网上节点分成一些相对独立的自治域,既提高了安全服务的可用性和可扩充性,也便于对某些紧急情况快速做出反应。
