摘要: 针对现有的多消息签名方案都需要有一个可信的第三者等问题,提出一个签名中心对特定用户的多消息签名方案。该方案基于双线性运算,引入t弹性的消息独立技术,当客户需要同时对多个消息的数字签名时,该签名中心能够同时签署多个消息,得到的多个签名的有效性可以被一次性(公开)验证,并给出方案的安全性证明。

关键词: 多消息签名, 短签名, 双线性对, 可证安全, 密钥独立

Abstract: Considering previous schemes need trusted third party, this paper proposes a multi-message signature scheme. The scheme is based on bilinear pairing and utilizing t key-evolving independence. Especially, when one client needs the signatures from the directed signature centre, the signature center can sign for many messages, and the signatures can be batch (publicly) verified. And its security is proved.

Key words: multi-message signature, short signature, bilinear pairing, provable security, key independence
