摘要
提出一种改进的椭圆曲线数字签名算法,该算法的设计有效地避免了求逆运算,提高运算速率.同时在签名算法中使用了SHA-256.该Hash函数作用在待签名消息m与它的签名r上,进一步确保算法的安全性.
An improved elliptic curve digital signature algorithm is proposed in this paper. This algorithm can avoid inversing effectively. Meanwhile the signature algorithm used relatively safe Hash function SHA - 256. The ＂m＂ ＂ SHA 256 has effect on news which waiting for sign and its signature r＂. It can ensure the safety of the algorithm further.
