摘　　要：基于椭圆曲线数字签名函数,提出了一种广播和有序相结合的结构化多重数字签名方案,并对算法进行安全性分析。该方案结构灵活,适合于各种复杂多重数字签名且能满足数字签名所要求的不可伪造性、不可抵赖性、抗合谋攻击、防止重发攻击、前向安全性等安全特性。Based on elliptic curve digital signature function, a structured multi-signature scheme with the combination of sequential and broadcasting algorithms is proposed in this paper. At the same time, we also analyze the security of the scheme. The scheme is more flexible than others and can be adapted to various complex multi-signature structures. It can also satisfy with the safety properties required by the digit- al signature including non-forgeability, non-repudiation, forward-secure, anti-collusion attacks, replay attack prevention and forward seeurity, etc.
