摘要
提出了一种广播多重量子数字签名方案,通过执行CNOT操作来对所要签名的信息进行加密,并利用幺正变换来实现信息的签名和验证.分析表明,本方案不受签名者多少的限制,具有可验证性,安全性高且技术实现简单,是一种可实现的广播多重量子数字签名方案.
A broadcast multiple quantum digital signature scheme was proposed,which encrypted messages to be signed by conducting CNOT operation,and used unitary transformation to realize information signature and validation.Analysis shows that,the scheme is not affected by the restrictions of the number of signers,capable of verifiability,high safety and simple technical implementation,and is thus a realizable broadcasting multiple quantum digital signature scheme.
