In this paper, a new E-payment system based on quantum blind and group signature is proposed. Existing E-payment systems based on classical cryptography cannot guarantee the security with the emergency of quantum computers. Compared to the existing E-payment system, our quantum E-payment scheme could protect not only the user’s anonymity but also the inner structure of customer group. In addition, our system adopts quantum key distribution, one-time pad, and audit mechanism to ensure unconditional security.
