摘　　要：首先提出一个基于椭圆曲线的ElGamal型广播多重数字签名方案。然后在此基础上设计了一个多重盲签名方案。并分析了两个方案的安全性和效率。该多重盲签名方案计算简单、安全并且效率较好。In this paper,first an ElGamal type broadcasting digital multi-signature scheme based on Elliptic Curve Cryptosystem is proposed. Then,a multi-blind signature scheme is designed based on the above scheme.The security and efficiency of these two schemes are analysed as well.The multi-blind signature scheme has the properties of simple calculation,security and efficiency.
