Abstract :
In this paper, we propose a practical ID-based (partially)blind signature scheme. Our scheme combines the already existing notions of blind signatures and identity-based cryptography.The signatures are shown secure in the random oracle model. We show how to use our ID-based PBSs to construct an electronic cash (e-cash) system in which multiple banks can securely distribute untraceable e-cash.
