摘　　要：按照三体纯态及其纠缠度量得出纯W-like态,提出基于纯W-like态的量子强盲签名协议。协议中应用量子密钥分发技术、指纹函数、量子一次一密算法,不仅能够有效隐藏用户身份,而且具有无条件安全、复杂度低及效率高的优点,是实现量子强盲签名协议的新途径。Aiming at pure three-qubit states and the measure of entanglement,this paper proposed pure W-like state.Based on pure W-like state,this paper proposed a strong blind quantum signature protocol.The protocol adopted the quantum key distribution,the quantum fingerprint and one-time pad.The protocol ensures that the signature is blind and the message owner is untraceable.Moreover,the protocol provides the unconditionally security,lower complexity and best quantum bit efficiency.This protocol is a novel method for constructing the strong blind quantum signature protocol.
