基于高维GHZ态的动态分层量子秘密共享协议
Dynamic hierarchical quantum secret sharing protocol based on high-dimensional GHZ state
摘要
Abstract
Quantum secret sharing is an important research branch of quantum cryptography.A novel dynamic hier-archical quantum secret sharing protocol based on high-dimensional GHZ(Greenberger-Horne-Zeilinger)state was proposed.In the presented protocol,participants were divided into multiple layers,with the number of participants and the shared secret in each layer being allowed to differ.Based on the entanglement characteristics between par-ticles in high-dimensional GHZ states,all participants at the same layer could cooperate to recover the secret of the current layer by performing local measurements.Moreover,each participant was able to obtain the shared secrets at lower layers,but not those at higher layers.In addition to the realization of the hierarchical structure,the proposed protocol also allowed each layer to dynamically add or delete multiple participants without changing the shares held by original participants,which provided better flexibility and generality.The correctness of the proposed proto-col was verified through mathematical proof.In addition,security analysis results showed that the proposed proto-col could resist intercept-and-resend attack,measure-and-resend attack,entangle-and-measure attack,Trojan horse attack,as well as collusion attacks from internal participants.关键词
