ECDSA快速验签算法

快速验签算法，Verification of ECDSA signatures is considerably slower than generation of ECDSA signatures. This paper describes a method that can be used to accelerate verification of ECDSA signatures by more than 40% with virtually no added implementation complexity. The method can also be used to accelerate verification for other ElGamal -like signature algorithms, including DSA -like signature algorithms, including DSA
