摘　　要：基于身份的密码体制(ID-based cryptography)是SHAM IR在1984年提出的,使用该体制进行加密、签名和认证可以有效地减小系统中用户的存储代价和运算量.将其应用到无线Ad hoc网络中,提出了一个基于身份的密钥管理方案.它采用基于身份的密码体制、秘密分享技术来实现私钥的分布式生成,并且利用盲短签名机制有效地实现了私钥的安全分发.该新方案可满足无线Ad hoc网络中密钥的安全需求,同时能节省网络资源、提高网络性能.ID-based cryptography was introduced by Shmir in 1984. With this scheme for encryption, signature and authentication can effectively reduce the cost of storage and computational in systems. In this paper, we propose a new key management scheme for wireless ad hoc networks based on it. The recently developed techniques of ID - based cryptography and secret sharing are deployed to realize the distributed generation of the nodes＇ private keys. It also makes use of the blind short signature to ensure the secure distribution of the private key shares of nodes in public channel. Our scheme can satisfy all the security demands of key in wireless ad hoc networks. It can also save the resource of the network so that the network performance is greatly improved.
