代理权可撤销的前向安全多重代理签名方案

Forward-secure multiple proxy signature scheme with proxy revocation

基于前向安全签名的思想,提出了一个代理权受保护的前向安全多重代理签名方案。该方案满足代理签名的五个安全需求:可验证性、强不可伪造性、强可识别性、强不可否认性、代理签名的可区分性;新的方案同时保护了代理签名人和原始签名人的权益,还具有前向安全性。分析表明该方案是安全且可行的。

This paper proposed a proxy-protected multiple proxy signature scheme based on the concept of forward secure signature.The new scheme satisfied five secure requirements of proxy signature,which were called verifiability,strong unforgeability,strong identifiability,strong undeniability and proxy signature distinguishability.The new scheme protected the rights and interests of proxy signer and original signer.In addition,the scheme was forward secure.It is proved that the proposed scheme is secure and feasible.
