摘要: 现有聚合签名方案的签名效率较低。为此,提出一种基于双线性对的无证书聚合签名方案。采用绑定技术,使用哈希函数将用户公钥绑定在部分私钥的生成及签名算法中,以解决无证书密码体制中存在的公钥替换攻击问题。分析证明,该方案能够预防适应性选择消息攻击下的存在性伪造,与已有方案相比,其有更低的计算代价。

Abstract: Aiming at aggregation signature scheme for the low efficiency of existing defects, this paper proposes a new certificateless aggregation signature scheme based on bilinear pairing. This scheme uses binding techniques and hash functions with the public key binded into the partial private key generating and signature algorithms. It can solve the problem that certificateless public key cryptography in the presence of two public key substitution attack. Analysis demonstrates that the scheme can prevent existential forgery under adaptive chosen-message attacks assuming. Compared with the known solutions, the proposed scheme has less calculating cost.

Key words: aggregation signature, bilinear pairing, certificateless aggregation signature, short signature
