Identity based blind signaturescheme based upon DLP

Abstract

Blind Signature scheme deals with the concept where requester sends the request that the signer should sign on a blind message. Anyone can verify the signature after publishing the information without any restriction. The proposed scheme having the property of both concept, Identity based as well as Blind Signature using DLP. With the help of Identity Based system we can easily archive the public key certification without key-management setting. In several ID based scheme ID map into an Elliptic curve, but we have a novel techniques to solve this problem. We have proposed a scheme that is based on Discrete logarithm problem.We have proved that our scheme meets all essential and secondary security prematurity. In addition we have given the mathematically and pragmatically correctness of our scheme. As our best of knowledge, we give the first discussion on these two notation. Also, we proved that our scheme fulfill all criteria that should be meet in a blind signature scheme.Our proposed scheme can be used in an E-commerce, E-voting and E-cashing anywhere without any restriction.We have given an application of E-cashing using our scheme.
