无证书公钥密码体制既克服了基于身份的公钥体制的密钥托管问题,又不需要像传统公钥体制那样管理公钥证书,是目前的研究热点. 而对于任何公钥密码体制,如何撤销一个用户是必须解决的问题. 然而,目前对无证书系统的撤销问题还缺乏理想的解决方案. 本文基于无证书加密,提出了1种高效的无证书系统的撤销方法,构造了1个具体的可撤销的无证书加密方案. 该方案不需要计算双线性对,密钥的更新在公共信道上就可以完成,所以我们的方案在效率方面远远优于现有方案. 在安全性方面,本文的方案达到了CCA2安全.

Certificateless public key cryptosystem,without certificate and key escrow problem,has received wide attention. For a public key cryptosystem,how to revoke a user is a necessary problem to be addressed. However,there still lacks good method to solve the revocation problem in certificateless setting. Based on certificateless encryption,this paper presents a revocation method by constructing a revocable certificateless encryption scheme. Our scheme does not need any bilinear pairing,and the key-update is done via public channels. So,our scheme is more efficient than the existing solutions. The new scheme reaches CCA2 security.
