辫群上代理签名体制的分析与设计
Analysis and design of proxy signature schemes over braid groups
摘要
Abstract
In order to research quantum cryptanalysis-resistant cryptographic schemes,this paper pointed the security vulnerabilities of two proxy signature schemes over braid groups that they could not resist the known-signature existential forgery attack. Then proposed a new proxy signature scheme based on the difficulty of the matching conjugacy search problem. Analysis shows that the proposed scheme satisfies the security requirements of proxy signature and has high computing efficiency and a short signature.关键词
