基于单态的量子隐私集合求交协议
Quantum private set intersection protocol based on singlet states
摘要
Abstract
Private Set Intersection(PSI)is an important cryptographic primitive.A quantum private set intersection(QPSI)protocol based on single-key encryption was proposed.In this protocol,an oblivious transfer was used as the information carrier,which was prepared by a semi-trusted third party.Each of the two participants encoded their private data set into the carrier particle based on the information.With the assistance of the semi-trusted third party,the participants could obtain the correct intersection without obtaining any information about the other party's set outside the intersection.The protocol of this paper could resist some common external and internal attacks.The protocol could be extended to the multi-party case and had good scalability.关键词
