Abstract: Based on the analysis of proxy multi-signature, multi-proxy signature, multi-proxy multi-signature and blind signature schemes, novel broadcasting and sequential multi-proxy blind multi-signature schemes based on Elliptic Curve Cryptography(ECC) are proposed by combining multi-proxy multi-signature with blind signature. Security of the new schemes is analyzed. Cryptanalysis shows that they both satisfy security requirements of multi-proxy multi-signature scheme and non-trail and blindness for blind signature.

Key words: digital signature, multi-proxy blind multi-signature, Elliptic Curve Cryptography(ECC), non-trail

摘要： 在讨论代理多重签名方案、多重代理签名方案、多重代理多重签名方案及盲签名方案设计原理的基础上，将多重代理多重签名方案与盲签名方案相结合，提出基于椭圆曲线密码的广播多重代理多重盲签名方案和有序多重代理多重盲签名方案，并对其进行安全性分析，分析结果表明，2类方案均满足多重代理多重签名的安全特性及盲签名的盲性和不可追踪性。
