摘要
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。结果在同等安全性下,该方案比通用的ECDSA等方案运行时间更短。新方案可适用于网络等对签名实时性要求较高的场合。
To offer a high efficiency digital signature based on elliptic curve cryptography. The design of the algorithm not only avoids timecosting inverse operation completely bat also uses the hamming weight of HASH code of a message instead of HASH code itself as the message digest to participate in the signature and verifying calculation. The new scheme cost less time than the popular ECDSA. The new scheme is adapted to higher real-time needs for signature such as internet.
