摘　　要：对基本的椭圆曲线数字签名算法(ECDSA)进行了改进,并在此基础上提出了一种多重数字签名方案。该方案签名长度固定,签名实体的密钥可自主选择,大大提高了安全性,而且签名实体并行签名,降低了总的签名时间。因此该方案具有计算量小、安全性高的特点,有着广阔的应用前景。The basic elliptic curve digital signature algorithm is improved, and a new multi-digital signature scheme is presented. In the scheme, the length of signature is fixed, and private keys are chosen by signers themselves, which enhances the security performance. Signers can sign the message simultaneously ,which reduces the total time of multi-signature. The scheme has the characteristics of less computation time, high security performance and good practicability.
