The Security Analysis of Forward-Secure Group Blind Signature Scheme Based on the Chinese Remainder Theorem

Abstract:

The paper analyzes a forward-secure group blind signature scheme based on the Chinese remainder theorem in cryptographic method, and points out that the attackers can tamper with the parameters of signature algorithm easily, which causes that the attackers revoke legal group members randomly .At the same time, the article proves the scheme does not have the feature of the blind signature .At last the author comes to a conclusion that the scheme is not safe.
