Description
Summary:We propose an identity-based proxy blind signature scheme from bilinear pairings which combines the advantages of proxy signature and of blind signature. Furthermore, our scheme can prevent the original signer from generating the proxy blind signature, thus the profits of the proxy signer are guaranteed. We introduce bilinear pairings to minimize computational overhead and to improve the related performance of our scheme. In addition, the proxy blind signature presented in This work is nonrepudiable and it fulfills perfectly the security requirements of a proxy blind signature.
