摘要
为实现一个盲代理签名方案能够同时代表多个原始签名人签名,人们提出了盲代理多重签名方案,克服了一个盲代理签名只能代表一个原始签名人签名的局限性.该文基于离散对数问题的困难性,在DSA变体盲代理签名的基础上,结合代理多重签名两种体制的优点,分别提出了具有盲代理签名和代理多重签名双重性质的第一类盲代理多重签名方案和第二类盲代理多重签名方案,并对两种方案的安全性进行了分析.
To realize that a blind proxy signature could be on behalf of multiple original signers, blind proxy multi-signature was presented. This kind of signature could overcome the limitation that a blind proxy signature could not be on behalf of more than one original signer. Besides, on base of discrete logarithm, a first class of blind proxy multi-signature scheme and a second class of blind proxy multi-signature scheme were proposed based on both DSA blind proxy signature scheme and proxy multi-signature scheme. They have the properties of two proxy signature schemes, and their security was demonstrated.
