Abstract:

A quantum signature protocol based on quantum one-time pad and quantum key distribution, in which the arbitrage didn’t do any operating, was presented. In the process of signature, message was transformed qubit, and the identity information of signer was attached to it. After signed, the signature message was transfer into frame structure by signer, and was transported to receiver. In the process of validation, both of communication sides must validate identity information and preserve this information each other, before the receiver wanted to obtain the information of the frame completely. Therefore the signature protocol attain the goal of non-deny.

Key words: quantun optics, quantum signature protocol, quantum one-time pad, frame structure
