摘要: 对蔡勉的多级代理签名方案(蔡勉,康莉. 一种安全的多级代理签名方案.中国科学院研究生院学报,2006,23(5):653-659)进行分析,提出了一种构造普通多级代理签名方案的方法,并与原方案进行了对比分析;利用普通的多级代理签名方案的构造方法构造了多级代理盲签名方案。经分析,新方案在代理部分避免了原始签名者伪造和签名接收者伪造攻击,其盲签名部分具有强盲特性。

关键词: 数字签名, 多级代理, 盲签名, 离散对数

Abstract: By analyzing Caimian’s multi-level proxy signature scheme (CAI MIAN,KANG LI.A secure multiple grade proxy signature scheme. Journal of the Graduate School of the Chinese Academy of Sciences, 2006,23(5):653-659), this paper proposed a thought of building an ordinary multilevel proxy signature scheme and made a comparison with the original scheme, and also proposed a new multi-level proxy blind signature scheme by using the thought of multi-level proxy signature scheme. the new scheme overcame original signer forgery attack in the proxy part and had strong blind property in the blind signature part.

Key words: Digital signature, Multi-level proxy, Blind signature, Discrete logarithm
