摘要
在基于椭圆曲线数字签名系统模型的基础上,提出了一种改进的数字签名算法,该算法通过消除影响数字签名效率的模逆运算,较大地提高了执行效率。在该签名方案的模型中加入了身份识别机制,保证了数据在传输中的安全性,也防止了签名的伪造。改进后的签名模型具有一定的实用价值。
On the basis of the digital signature system model based on elliptic curve,an improved digital signature algorithm is proposed.The algorithm greatly enhances execution efficiency by eliminating modular inverse operation which influences the efficiency of digital signature.Moreover,the identification mechanism is added in the signature scheme model,it ensures data transmission security and prevents forged signature.The improved signature model is of certain practical value.
