Implementation of Multi Signature Scheme Using Elliptic Curve Digital Signature Algorithm

Abstract

Multi signature schemes provide data authenticity integrity, and non repudiation. The proposed signing and verifying schemes are extensions of standardized algorithms ECDSA (Elliptic Curve Digital Signature Algorithm). These schemes are faster than repeated E CDSA ( RECDSA). ECDSA schemes can be dire ctly used in many applications, such as E Business for a joint signature of a contract between two or more organizations, or E Government. The final multi signature of a message can be verified individually for each signer or collectively for a subgroup or entire group as well.
