摘要：Due to the increasingly serious information attacks in network times, the electronic commerce is fac- ing additional challenges in the aspects of security and efficiency. Therefore, in this paper, we pro- pose a new practical e-cash protocol based on dynamic group signature in BSZ model, using the Non- Interactive Zero-Knowledge proofs system. And it is proved that our protocol satisfies anonymity which resists chosen-ciphertext attack, unforgeability, traceability, and no double-spending with- out random oracles. Compared with the existing protocols, our protocol not only permits dynamic enrollment of members and non-interactive during transmission, but also offers lower storage and communication cost
