This paper describes a new variant level of Signature Scheme on ECDSA. In support of this scheme, a study of on a number of schemes was done. The number of scheme includes Lamport, Schnorr, DSA etc., In this study three schemes, DSA, ECDSA and Variant ECDSA are taken for a comparative study. From that comparison, the paper tries to develop a new scheme on ECDSA. Finally, It was found out that, Variant signature on ECDSA is better than other schemes. We give a brief preamble to the Signature Algorithm in chapter 1 and then give the Concepts of the Elliptic Curve version of DSA. Finally a Variant of ECDSA will be given in chapter 9.
