【摘要】 首次提出一个新的利用椭圆曲线上双线性对的基于身份的多签名体制。所提出的体制基于Hess的基于身份的签名体制,能实现并行和串行的签名结构,而且在此新多签名体制中,多签名的大小和验证与任意共同签名者产生的单个签名完全相同。同时也讨论了新体制抵抗外部攻击和内部攻击的安全性。更多还原

【Abstract】 This paper presents for the first time an identity-based multisignature scheme which makes use of bilinear pairings on elliptic curves.The proposed scheme is based on Hess’s identity-based signature scheme and can realize signing structures of parallel and serial.Moreover,in this new multisignature scheme ,the size and the verification of a multisignature is the same as those of an individual signature generated by any co-signer.It also discusses the security of the new scheme against outsider attack and insider attack.更多还原
