摘　　要：利用组合公钥体制(CPK)的基本思想,结合椭圆曲线加密(ECC)算法,提出了一种改进的数字签名方案。该方案中,签名者使用双私钥对消息进行签名,并通过结合运用CPK和ECC的特点,实现了高效的密钥管理以及高可靠性,较传统数字签名方法有更高的安全性和方便性。最后,对该签名方案进行了安全性分析。This paper represents an improved method of digital signature, which is based on the principle of combined public key （CPK） and combined with the algorithm of elliptic curve cryptosystem （ECC）. In this method a pair of private keys are introduced to sign the message, and via the combination of CPK and ECC, effective management of keys and high reliabihty have been achieved. Compared with the traditional methods of digital signature, it is more seeure and convenient. At last, the security of this method has been analyzed.
