A Novel ECDLP-Based Blind Signature Scheme

Abstract

In this paper, a novel Blind Signature Scheme (BSS) based on Elliptic Curve Discrete Logarithm Problem (ECDLP) has been proposed. The signer signs the encrypted message after receiving it from the requester. Hence the signer has no scope to learn the contents of the message that he has signed. But there is a scope to verify the authenticity of the signature on the original message by the requester and any other third party. The model has been validated using a customer and bank example and the proof of correctness has been made. The applicability of the proposed scheme can be extended to e-voting and others where the requester needs a blind signature on the message.
