摘要/Abstract

摘要： 分析了一个基于属性签名方案的安全缺陷,并改进了Li等人的基于属性签名方案,从而减少了签名计算代价和签名长度。在随机预言机模型下,利用CDH问题的困难性,证明了改进方案满足在适应性选择消息和断言下的不可伪造性。改进方案还满足签名者属性隐私安全。仿真实验结果表明,改进方案可以较好地应用于移动对等网络数据分发,以实现消息认证。

Abstract: Security flaw of an attribute-based signature was pointed out and analyzed firstly,and on the basis of Li’s attribute-based signature (ABS),a new efficient ABS was proposed,in which signing cost and signature size are decreased．The proposed ABS is proved secure in the random oracle machine and satisfies existential unforgeability against adaptive chosen message and predicate attack based on the standard computational Diffie-Hellman assumption．Furthermore,it provides attribute-signer privacy．Result of simulation shows that the proposed ABS can be well applied to data dissemination in mobile peer-to-peer network to achieve message authentication.

Key words: Attributes-based signature,Dynamic threshold,Attribute signer-privacy,Random oracle model
