Proxy blind signature which combines the properties of both proxy signature and blind signature. In a proxy blind signature scheme, the proxy signer is allowed to generate a blind signature on behalf of the original signer. The proxy blind signature scheme is useful in several applications such as e-voting, e-payment and mobile agent environments. In thispaper, we present an efficient proxy blind signature scheme based on discrete logarithm problem, which satisfies the secure properties of both the blind signature scheme and the proxy signature scheme with low computation. Analysisshows that our scheme is secure and efficient.
