摘　　要：对田娟红等人提出的鲁棒的多重代理多重盲签名方案进行密码分析,发现方案不能抵抗伪造攻击.对其进行改进,提出了一个新的门限多重代理多重盲签名方案.证明了改进方案具有盲性和适应性选择消息攻击下的存在不可伪造性.The cryptanalysis of the robust multi-proxy multi-blind signature scheme proposed by TIAN Juanhong et al.reveals that the scheme can not resist the forgery attack.A new improved threshold multi-proxy blind multi-signature scheme is proposed.The analysis results show that the improved scheme can achieve the blindness and existential unforgeability against the adaptive choose message attack.
