Abstract

In the quantum cheque schemes that have been proposed, a strong quantum capability of the user is required and the quantum resources consumption is relatively high. To solve this problem, we propose a quan tum cheque protocol based on quantum state computational distinguishability, in which a bank issues a blank cheque, a semi-classical user can sign the amount on the cheque and finally the bank verifies the validity of the cheque. Compared to existing scheme, our scheme requires less quantum capability and reduces the overhead of quantum resource. Since the scheme is based on a hard problem that can resist quantum attacks, the quantum cheque cannot be forged or altered.
