前向安全的无证书强代理签名方案

Certificateless Strong Proxy Signature Scheme with Forward Security

文章基于文献[1]中的无证书强代理签名方案,利用文献[2]的方法,首次设计出一个前向安全的无证书强代理签名方案,并在代理签名的安全模型下证明了其安全性。效率分析表明,本文设计的签名方案保持了文献[1]中方案的高效性,但却提供了强代理的安全性和前向安全性。

Based on the scheme in reference[1] and the method in reference[2],a certificateless strong proxy signature scheme with forward security is proposed for the first time,and its security is proved.Efficiency analysis shows that the new scheme keeps the high efficiency of the scheme in reference[1],and offers strong proxy security and forward security.
