ID-based Proxy Blind Signature Scheme

Proxy signature and blind signature are useful tools in cryptography.They both have wide applications in real life.In a proxy signature,an original signer can delegate his signing power to a proxy signer who signs a message on behalf of the original signer.A blind signature has a salient feature that the signer can not make a linkage between the blind signature and the identity of the requester.Based on bilinear paring and an ID-based signature scheme,an ID-based proxy blind signature scheme is presented,which satisfies the security properties of both proxy signature schemes and blind signature schemes.A simple security analysis of the newly proposed scheme is also given.
