Generalization of Elliptic Curve Digital Signature Schemes

ECDSA can be viewed as the elliptic curve analogue of DSA. Many variants of (ElGamal) DSA and some general types were proposed in [4]. In this paper, several general types of ECDSA and some new variants of the basic ECDSA are described. From these general types, we can extract the desired, high efficient elliptic curve digital signature schemes. Moreover, their related securities are briefly analyzed.
