摘　　要：量子盲签名作为量子密码学的重要组成部分,近年来受到了越来越多的关注。提出了一个基于两粒子和三粒子最大纠缠态的量子盲签名方案,利用量子纠缠特性实现了消息盲化,并借助量子相干性原理进行了消息恢复。所提方案利用量子逻辑门对量子态进行操作,实现了两比特经典信息的量子态表示。最后证明了该方案满足不可否认性、不可伪造性和盲性。基于量子密钥分发和一次一密技术,所提方案的无条件安全性得到了保证,且与现有其他方案对比,该方案有较高的签名效率。As an important part of quantum cryptography,quantum blind signature has attracted more and more attentions in recent years.A protocol of quantum blind signature based on two-qubit and three-qubit maximally entangled states is proposed.By using the special characteristics of quantum entanglement,the blindness of a message is realized,and the recovery of this message is conducted by the help of the quantum coherence principle.In the proposed protocol,the operation on qubits via quantum logic gates is used for the realization of the quantum state expression of two-bit classical information.Finally the proposed protocal is confirmed to satisfy the properties of undeniability,unforgeability and blindness.Based on the quantum key distribution and one-time pad technology,the absolute security of the proposed protocol is guaranteed.Moreover,the proposed protocol is more efficient than other existing protocols.
