基于分簇结构的Ad Hoc网络中门限密钥管理方案

Cluster-based Threshold Key Management Scheme in Ad Hoc Network

基于分簇的网络结构给出了一种新的Ad Hoc网络密钥管理方案.方案中无需可信赖的第三方,并且使用了门限技术将PKG(public key generation)的功能分散到簇头节点上,提高了系统的安全性.采用基于身份的加密算法,用户之间无需进行公钥认证,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.

Promotes a cluster-based threshold key management scheme. In this scheme, public key certificates are not needed and every participant can use his identity as public key, and the function of PKG （Public Key Generation） is distributed to the cluster head nodes. It greatly decreases the need of the ability for computation and storage of clients＇ terminals, as well as communication overhead for system key management.
