基于量子漫步密码体制,提出了一种巧妙的簇态量子盲签名方案,利用量子漫步生成密钥。包括初始阶段、签署阶段和验证阶段。在签名阶段,Alice将加密消息发送给签名者Charlie,并请求量子盲签名。在验证阶段,验证器Bob根据最终测量结果验证消息的真实性和完整性。安全性分析表明,密钥和签名方案的安全性是不可伪造的,也不能被非法参与者或攻击者否认。与以往的签名方案不同,该方案首先将量子行走算法应用到签名方案中,对原始消息进行加密。重要的是,它在电子商务或电子支付系统中有着广泛的应用。
An ingenious quantum blind signature scheme with cluster states based on quantum walk cryptosystem is proposed, in which the keys are generated with quantum walks. Initial phase, signing phase and verification phase are included. In the signing phase, Alice sends the encrypted message to the signer Charlie and requests a quantum blind signature. In the verification phase, the verifier Bob verifies the authenticity and integrity of the message based on the results of the final measurements. The security analysis shows that the security of secret keys and the signature scheme, and it can be neither forged nor disavowed by illegal participants or attackers. Different from previous signature schemes, the original message is encrypted by the quantum walk algorithm, which is firstly applied to the signature scheme. Importantly, it has a wide application in e-commerce or e-payment system.
