摘要
A third-party E-payment protocol based on quantum group blind signature is proposed in this paper. Our E-payment protocol could protect user’s anonymity as the traditional E-payment systems do, and also have unconditional security which the classical E-payment systems can not provide. To achieve that, quantum key distribution, one-time pad and quantum group blind signature are adopted in our scheme. Furthermore, if there were a dispute, the manager Trent can identify who tells a lie.
