A New Proxy Blind Signature Scheme Based on DLP

Swati Verma, Birendra Kumar Sharma

Abstract


A proxy blind signature scheme is a special form of blind signature which allows a designated person called proxy signer to sign on behalf of two or more original signers without knowing the content of the message or document. It combines the advantages of proxy signature and blind signature and satisfies the security properties of both proxy and blind signature scheme. In this paper, a new proxy blind signature scheme based on discrete logarithm problem (DLP) has been proposed, which satisfies the security properties of both the blind signature and proxy signature. Security analysis also given which shows that our scheme is secure and efficient.
