摘　　要：量子盲签名作为量子密码的重要组成部分,近年来备受关注,半量子协议为量子盲签名走向实用化提供了可行性方法。结合半量子概念和抵抗集体噪声的逻辑粒子,提出了免疫集体噪声的半量子盲签名协议。在协议中,只有签名方Charlie具备完整的量子能力,这使得该协议对量子资源的依赖大幅降低。通过安全性分析可以证明:本协议能够抵抗内部攻击、纠缠测量攻击和截断重发攻击等,实现了部分密钥的可复用性,同时能够扩展到量子签名网络,实现跨区域的量子签名。As an important part of quantum cryptography,quantum blind signature has attracted more and more attention in recent years.Semiquantum protocol provides a feasible method for the practical application of quantum blind signature.In this paper,a semiquantum blind signature protocol against collective noise is proposed by combining the semiquantum and logical qubits resisting collective noise.In the protocol,only the signer Charlie has the complete quantum capability,which makes the demand for quantum resources of the protocol drop drastically.Through security analysis,the protocol can resist internal attack,entanglementmeasurement attack and interceptresend attack.The protocol implements reusability of keys and the scheme can be extended to quantum signature networks to realize crosscenter quantum signature.
