量子不经意传输及其应用
Experimental Quantum Oblivious Transfer and Its Applications
摘要
Abstract
Secure multiparty computation(MPC)enables computations across multiple users while preserving individual privacy and has a wide range of applications.MPC can be realized using obliv-ious transfer(OT)as a primitive function.Conventional OT protocols are based on mathematical assumptions such as discrete logarithm,which are vulnerable to quantum attacks.Quantum oblivious transfer(QOT),assuming the existence of additional functionality primitives,offers a quantum-secure alternative.This study experimentally implements a quantum secure QOT protocol that surpasses the noisy storage model using a bit commitment scheme.Then,this QOT protocol is applied to solve the Yao's Millionaires' Problem,which is a typical example of secure multi-party computation,where two parties aim to compare the size of their private inputs without revealing any additional information.关键词
