一种指定验证人代理签名方案的安全性分析
Security analysis of a designated-verifier proxy signature scheme
摘要
Abstract
In the light of the security analysis of a designated‐verifier proxy signature scheme with fast proxy right revocation proposed by Tian et al , it is found that the scheme could not resist public‐key substitute attacks and forgery attacks , and it is not satisfied the restrictive verifiability . In order to resolve the security problem existing in Tian's scheme , a new designated‐verifier proxy signature is proposed , w hich meets the safe requirements of designated‐verifier proxy signature and can resist public‐key substitute attacks and forgery attacks .关键词
