一种不含双线性对的无证书有序多重签名方案*

提出了一种不含双线性对的无证书有序多重签名方案,即结合不含双线对运算的无证书签名和有序多重签名的思想。与一般无证书数字签名体制不同的是,不含双线性对运算的无证书密码体制没有复杂的双线性对运算,且在计算效率方面具有明显的优势。最后对方案进行安全分析,能抵抗替换公钥攻击,安全性较高。

Certificateless sequential multi-signature scheme without pairings

This paper proposed a certificateless sequential multi-signature scheme without pairings, it combined the theory with certificateless signature without pairings and sequential multi-signature. Compared with the general certificateless digital signature system, certificateless signature scheme without pairings had no heavy cost pairing operation and obvious advantages in the calculation efficiency. Finally, through the security analysis, the signature scheme can resist the attack of the replace public key and the safety is higher.
