Abstract

Abstract: According to the Micali’s notion of fair cryptosystem，a fair group blind signature scheme is presented with an oblivious transfer protocol.It is based on the first CS97 group signature scheme.It not only meets the need of group blind signature，but also has the additional property that，with the help of a trusted entity，it is possible for the signer to link a message-signature pair and the corresponding signing protocol.So it can prevent criminals from participating in illegal activities.

Key words: group signature, group blind signature, oblivious transfer, fair group blind signature

摘要： 根据Micali公平的密码体制的思想，基于CS97的第一个群签名方案，利用不经意传输协议提出了一个公平的群盲签名方案。它除了满足群盲签名的要求以外，还有一个附加的性质，即在一个可信实体的帮助下，签名者能够将消息签名对与相应的签名协议联系起来。这样就可阻止不法分子利用群盲签名从事犯罪活动。
