Probabilistic Attacks and Enhanced Security for "Private Set Intersection in the Internet Setting from Lightweight Oblivious PRF"
Abstract
Privacy Set Intersection (PSI) has been an important research topic within privacy computation. Its main function is to allow two parties to compute the intersection of their private sets without revealing any other private information. Therefore, PSI can be applied to various real-world scenarios.
Chase and Miao presented an impressive construction ``Private set intersection in the Internet setting from lightweight oblivious prf'' (CM20 for short) at Crypto 2020, highlighting its convenient structure and optimal communication cost. However, it does have some security vulnerabilities. Let
