摘要
提出了一种新型代理签名方案,其安全性是建立在因子分解表述难题之上,因而不是基于离散对数密码体制的方案。安全分析表明它是一种弱代理签名方案,不属于强代理签名。
A new proxy signature scheme is proposed. The security is based on factoring representation problem, so it is not based on the discrete logarithm problem cryptosystem. The analysis of security shows that it is a weak proxy signature scheme and does not belong to a strong proxy signature scheme.
