摘要
由于无证书密码体制可以避免证书管理和密钥托管问题,近年来成为密码学界研究的热点之一,很多无证书代理签名方案(CLPS)被提出。针对目前很多无证书代理签名方案都是基于双线性对设计的,具有效率低和应用中实现困难的问题,本文提出一种基于RSA的无证书广播多重代理签名方案。基于RSA问题,分析了方案的安全性,与已有方案的效率相比,新方案的效率更高。
The certificateless cryptography has become one of the hottest topics concerned in recent years,for which can overcome certificate management and key escrow problem,and many certificateless proxy signature schemes have been proposed. Aimming to these schemes proposed based on bilinear pairing have the problem of low efficiency and realizing difficult in application,a certificateless broadcasting multi- proxy signature scheme based on RSA is proposed. Based on RSA problem,the security of the new scheme is analyzed in detail. Compared with the existing schemes,the new scheme is more efficiency.
