基于量子一次一密和量子密钥分配,提出了一种在签名及验证过程中没有仲裁参与操作的量子签名协议。在签名过程中,将消息转化为量子比特,在量子比特上进行签名并附上和消息相关的身份信息。签名消息的传输文件采用帧结构的形式,在验证过程中,通信双方完全读取帧文件内容需要相互确认身份,并留下与消息相关的身份信息,因此满足了签名协议的不可否认性。
A quantum signature protocol based on quantum one-time pad and quantum key distribution was presented, in which the arbitrage didn't participate in. In the process of signature, message was transformed to qubit, and the identity information of signer was attached to it. After signed, the signature message was transfered 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 attains the goal of non-denial.
