摘　　要：本文从椭圆曲线离散对数问题(ECELP)出发,针对现有的椭圆曲线数字签名算法(ECDSA),提出了两个基于椭圆曲线的多重签名方案,包括按序多重签名和广播多重签名,基于计算量和效率,又提出了另外一种椭圆曲线的广播多重签名。它们都满足数字签名的基本要求,并具有良好的安全性和实用性。Based on the Elliptic Curve Digital Signature Algorithm（ECDSA）,multi signature schemes are proposed, which include both sequential multi signature and broadcasting multi signature.In addition,another broadcasting multi signature was proposed,which is more efficient than the former one.All multi signature schemes meet the basic needs of digital signature,and have good security and feasibility.
