A Novel ECDLP-Based Blind Signature Scheme with an Illustration

Abstract

Blind signature allows a requester to obtain signature from a signer on any document in such a way that, the authority learns nothing about the message that is being signed. Due to the blindness and untraceability properties of Blind Signature Scheme, it can be used in cryptographic applications such as web based e-voting, digital cash etc. In this paper, a novel blind signature scheme based on Elliptic Curve Discrete Logarithm Problem has been proposed. The model has been explained using a customer-and-bank example and the proof of correctness has been made.
