本文提出了一种基于椭圆曲线(ECC)的DSA的(n,t)门限数字签名方案,方案由四个部分组成:系统参数的建立、子密钥产生、签名算法过程和签名算法验证四个部分组成.DSA具有ElGamal签名和Schnorr签名的特点,又由于该方案是基于椭圆曲线密码体制和DSA密码体制基础上,因此保证了方案的安全性.

A new digital signature scheme which based on elliptic curve (ECC) of the DSA (n, t) threshold digital signature scheme is given in this paper, and reform program to improve . the program is composed of four parts, namely, system initialization, the sub--key generating process, the process of signing and signature verification of four parts. DSA signature with ElGamal signature and Schnorr characteristics, and because the program is based on elliptic curve cryptosystem and eryptosystems based on the DSA to ensure the safety of the program.
