The concept of proxy multi-signature scheme is first introduced by the researcher in 2000. In a proxy multi-signature scheme a proxy signer can generate a proxy signature on behalf of two or more original signers. In this paper elliptic curve cryptography is used to implement proxy multi-signature scheme. Hence it provides a secure signature scheme. Today, elliptic curve cryptosystems are offering new opportunities for public-key cryptography. In the industry and the academic community, Elliptic Curve Cryptography (ECC) has gained increasing acceptance and has been the subject of several standards.
