有效的有序多重数字签名方案

指出了文献1]方案中存在的安全性问题,随后利用椭圆曲线密码算法设计了一个新的有序多重数字签名方案,且不使用哈希函数和消息冗余函数,减少了这方面所带来的安全威胁;取消了施方案里的签名中心,避免了该签名中心的参与导致计算瓶颈的产生;所有消息均公开,签名者可以共同通过验证来发现伪签名和成员内部的欺诈行为.此方案能够克服施方案的安全问题,并且计算量小,结构简单,具有一定的实用价值.

Efficient sequential digital multi-signature scheme

The insecurity problem in reference 1] is pointed out,and a new sequential digital multi-signature scheme based on ECC is constructed.This scheme didn't use hash functions or redundancy functions and cancel the signature centre.All the messages in the scheme will be public,signers can validate the signatures to discover fake signature and avoid the cheating by inner users.The scheme can solves the insecurity problem,and will be have lower computation,higher safety,simpler structure and more applied value than Shi's scheme.
