摘要:

文章利用量子特性提出了一种量子多重代理盲签名方案。方案中消息的拥有者参照消息与单量子态的对应关系将签名消息转化为量子序列,同时根据密钥对其做酉变换将消息盲化,然后将消息序列发送给原始签名者。原始签名者利用密钥完成签名授权,将签名权给代理签名者;代理签名者利用对单量子的酉变换完成自己的签名。验证者通过对最终签名的测量对比完成签名验证。方案不需要使用多粒子纠缠量子态,签名时只需要对单量子态做酉变换,验证签名时只需要对单量子态进行测量,过程简单高效,签名的信息也不会随着签名者的增加而变长,代理签名者的删除和加入容易操作。分析表明所提出的方案是一个可实现的、高安全的量子多重代理盲签名方案。

Abstract:

Based on quantum properties, a multi-proxy blind signature scheme was proposed. In the scheme, the owner of the message transform message into single quantum state according to corresponding relation between the single quantum state and the message. Then he completes blind message by unitary operation according to the secret key. Proxy signers use unitary transformation of single quantum to complete signature and verification. The scheme does not need to use multi particle entangled quantum states and Verifier Only need to measure single quantum state when verifying the signature. The process is simple and efficient process, at the same time, the information of the signature does not become large with the increase of the signer. The deleting and adding of the proxy signer is easy to operate. The security analysis of the scheme shows that it is a secure and achievable quantum multi-proxy blind signature scheme.

Key words: quantum information, quantum signature, multi-proxy blind signature
