Provably Secure Self-Certified Partially Blind Signature Scheme from Bilinear Pairings

To enable the practical electronic cash systems, significant attention has been paid to the partially blind signature because of its unlinkability and unforgeability. To the best of our knowledge, most of partially blind signature schemes are constructed under either the traditional public key certificate based system or the ID-based system, which may incur significant efforts in certification management and/or revocation. In this paper, we introduce a novel approach for partially blind signature with self-certified public keys. This is the first research effort for significantly reducing the certificate management and revocation in partially blind signature, and is characterized by the adoption of bilinear pairings and the analytic techniques of provable security.
