基于类GHZ态和Bell态纠缠交换的半量子隐私比较
Semiquantum Private Comparison Based on Entanglement Swapping of GHZ-Like State and Bell State
摘要
Abstract
This paper proposed a protocol of semiquantum private comparison(SQPC)based on entanglement swap-ping of GHZ-like state and Bell state,which allows the classical participants to compare the equality of their secret message under the help of a semi-honest third party(TP).TP is allowed to misbehave but cannot collude with anyone else.This pa-per provides a detailed proof of the protocol's complete robustness against external eavesdroppers'attacks,and analyzes its security against dishonest internal participants.This paper also conducted experimental simulations on the flow and output correctness of the protocol using IBM's Qiskit.In addition,the security of the proposed protocol is confirmed and it can ef-fectively prevent various kinds of attacks.关键词
