摘　　要：隐私集合求交(Private Set Intersection,PSI)是一种保护数据隐私的集合计算技术,允许互不信任的各方协同计算私有数据的交集,且不透露交集以外的任何信息。PSI技术被广泛研究和应用,主要从提升性能和探索新型应用场景两个方面发力。首先详细梳理两方PSI的研究进展,分析和评估业界先进的算法协议;其次以卫星互联网新型应用场景为例,探索提出高性能两方PSI应用方案,实验测试不同数据类型在多种网络环境下的性能,给出新型场景下的PSI实践范式。最后进行总结与展望,给出了PSI的发展思考与建议。PSI(Private Set Intersection)is a set computing technology that protects data privacy by allowing mutually untrusting parties to collaboratively compute the intersection of private data without revealing any information beyond the intersection.PSI technology is widely studied and applied,mainly from the two aspects of improving performance and exploring new application scenarios.First,the research progress of the two-party PSI is reviewed in detail,and the advanced algorithm protocols in the industry are analyzed and evaluated.Then,taking the new application scenarios of satellite Internet as an example,the highperformance two-party PSI application scheme is explored and proposed,and the performance of different data types in various network environments is tested through experiments,which gives the practical paradigm of PSI in the new scenarios.Finally,a summary and outlook are provided,along with considerations and suggestions for the development of PSI.
