摘　　要：结构化多重数字签名允许签名团体按照特定的签名结构进行签名。签名结构可以是有序的,广播的或两者相结合的。首先针对有序的签名结构提出了一种算法,其实现关键在于按签名顺序的倒序生成签名公钥,随后扩展了签名结构,将其中的某些节点更改为由多个按广播结构签名的签名者组成的虚拟节点,并改进了算法,提出了结构化多重签名算法。两种算法均基于椭圆曲线密码体系,具有较高安全性。最后通过实验对两种算法进行了模拟。A structured digital mulitsignature allows signers to sign messages in compliance with specified signing structure, which can be sequential, broadcasting or combination of them. This paper firstly presented an algorithm with sequential structure, for this algorithm, that pubic keys were produced by the reverse signature order was essential to implementation, then the structure was expended to a new one where some nodes were changed to dummy ones composed by some signers whose signature is broadcasting, and the algorithm was mended for a new structured muhisignature algorithm. Both of them were based on Elliptic Curve Cryptosystem （ECC） and had high security. Finally, the two algorithms were simulated through experiments.
