基于椭圆曲线的一种高效率数字签名。为给出一种基于椭圆曲线密码的高效率的数字签名方案。不仅在算法设计时完全避免了费时的求逆运算，而且利用消息HASH值的汉明重量作为消息摘要进行签名与验证。-Based on elliptic curve digital signature of a high efficiency. For a given elliptic curve cryptography based on an efficient digital signature scheme. Algorithm is designed not only completely avoid the time-consuming inverse operation, and the use of information HASH value of the Hamming weight as the message digest for signature and verification.
