摘　　要：提出了一种ElGamal型有序多重数字签名方案,在该方案中允许多方对同一文件进行顺序签名,但签名的长度和验证签名的时间不随签名人数的增加而增加;并且在整个签名与验证过程中避免了费时的求逆运算,提高了运算效率,具有较强的实用性.This paper proposes a kind of EIGamal-type sequential multi-digital signature scheme, this schemeallows many people to conduct sequential signature for the same file but the .signature length and the time for verifying the signature do not increase with the increase of the number of signature people, furthermore, in the whole process of signature and signature verification, the time-consuming reverse operation is shunned, as a result,this scheme improves operation efficiency and has strong practicability.

关 键 词：圆锥曲线 离散对数 有序多重数字签名
