摘　　要： 提出了一种基于秘密共享原理的量子强盲签名协议.每一组GHZ(Greenberger-Home-Zeilinger)中的三个光子依次分发给消息拥有者Alice、签名者Trent及验证者Bob,Alice测量自己的光子将消息盲化,Trent测量自己的光子对盲消息进行签名,而Bob根据手中光子的测量结果及量子态的关联性验证签名,但其行为受到量子指纹及审计程序的约束.本协议实现了签名的盲性以及消息拥有者无法被追踪,其安全性不受攻击者所拥有的计算资源的影响. A strong blind quantum signature protocol was presented based on secret sharing.In this protocol,the three pho-tons of each GHZ（Greenberger-Horne-Zeilinger）triplet are delivered to the message owner Alice,signatory Trent and verifier Bob respectively.Alice measures her photon to blind her message while Trent measures his photon to sign the blinded message,and then Bob verifies the signature according to the measuring results of his photon under the relationship of GHZ states.However,Bob＇s ac-tions are restricted by the quantum fingerprints and the audit program.Our protocol ensures that the signature is blind and the mes-sage owner is untraceable.Moreover,its security was not influenced by the computational resource of attackers.
