Blind Proxy Blind Signature Scheme on Elliptic Curve

Abstract

Aiming at the problem that current schemes can not protect the benefits of proxy signer and message owner at the same time,this paper presents a blind proxy blind signature scheme on elliptic curve. By using Elliptic Curve Cryptography(ECC) and zero-knowledge proof,it has small amount of computing,high security and high implementation efficiency. Security analysis proves that the scheme satisfies the security properties of blind proxy signature scheme and proxy blind signature scheme,and it has strong enforceability.
