摘要
为了降低秘密集中度,提高秘密共享协议的可靠性和安全性,基于多目标量子远程通信,提出了一个新的秘密共享协议。为安全分发秘密量子信息,Alice制备多光子处于最大纠缠态,自己保留一个,把剩余的光子分发给各个秘密共享者。通过对量子信息态和自己保留的光子做Bell基测量,Alice将秘密量子信息转移到秘密共享者所拥有的光子上。要恢复该秘密量子信息,所有秘密共享者需提供各自的光子。对协议的安全性分析表明了该协议的安全性和可行性。
A novel secret sharing protocol based on multi-target quantum teleportation was proposed to reduce the concentration of the secret and enhance the security of the secret sharing protocol. To distribute the secret safely, Alice prepares some entangled photons, after reserving one as his own, he distributes each of the others to each secret sharer. Then Alice transfers the secret quantum information to the photons of the secret sharers through a Bell state measurement between the secret quantum state and his own photon, Only after all the sharers put their photons together can the secret quantum information be reconstructed. Analytical results show the proposed protocol is secure and feasible.
