摘　　要：在分析了门限代理签名方案和代理多重签名方案的基础上,提出了一种基于椭圆曲线的门限代理多重签名方案。该方案可以实现多个原始签名人将签名权转交给多个代理人,并用(t,n)门限签名实现成员数为n的代理组中任何t个代理签名人就可代表原始签名人生成有效的签名。由于基于椭圆曲线密码体制,使得该方案的计算量和通讯量都较小。On the cryptanalysis of threshold proxy signature scheme and multi signature scheme, a threshold proxy and multi signature scheme based on elliptic curve is presented. In the scheme ,multiple-original signers can delegate their signing capability to a group of proxy signers and any t of the group of proxy signers which has n persons can represent original signers to generate effective signed by using （t,n） threshold signature scheme. Because it is based on elliptic, the computation and the traffic of this scheme are both small.
