一种可多人验证的量子多重代理盲签名方案

多数情况下签名者只有一个人。当原始签名人无法亲自签名时，为了保证文件的有效性、防止权利过于集中，他可以委托多个人对文件进行签名和验证。方案采用量子密钥分发协议保证安全性，并利用幺正变换进行签名和验证，对签名和验证的顺序没有要求，并且签名和验证人数可以不同，提高了工作效率。正确性和安全性分析表明该方案技术实现简单，能够抵御主动和被动攻击，是一种安全的可实现量子多重代理盲签名方案。

A quantum multi-proxy blind signature scheme with multiplayer verification

In most cases, there is only one singer. When the original signer can’t sign the document personally, in order to ensure the validity of the document, and prevent excessive concentration of the rights, the signer can entrust more than one person to sign the document and validate it. Quantum key distribution protocol is used to ensure the security, and the signature and verification are carried out by using unitary transformation. There is no requirement for the order of signature and verification, and the number of signature and verification can be different, which greatly improve the work efficiency. The correctness and security analysis show that the technical implementation of the scheme is simple, and it can resist active and passive attack. It is a safe and realizable quantum multi-proxy blind signature scheme.
