基于量子委托计算模式的半量子密钥协商
Semi-quantum Key Agreement Based on Delegating Quantum Computation Mode
摘要
Abstract
In order to reduce the cost of quantum devices and perform quantum computing better,a multiparty semiquantum key agreement protocol based on delegating quantum computation mode is proposed.Delegating quantum computation model is introduced.The complicated operations such as unitary operation and Bell measurement are entrusted to the quantum center.Participants only need the simple ability of accessing quantum channel and preparing single photons.In order to prevent key information from being stolen by quantum center or outside attackers,the confusion strategy of inserting confusion single photons into target states is used to keep target states safe.Analysis results show that compared with previously quantum key agreement protocols,the quantum capabilities required by the participants significantly decrease,thus improving the practical feasibility of the protocol.关键词
