SpOT-Light: Lightweight Private Set Intersection from Sparse OT Extension
private set intersection OT extension
2019/6/4
We describe a novel approach for two-party private set intersection (PSI) with semi-honest security. Compared to existing PSI protocols, ours has a more favorable balance between communication and com...
Cheaper Private Set Intersection via Differentially Private Leakage
private set intersection differential privacy
2019/3/4
In this work we demonstrate that allowing differentially private leakage can significantly improve the concrete performance of secure 2-party computation (2PC) protocols. Specifically, we focus on the...
The Communication Complexity of Threshold Private Set Intersection
Communication Complexity Private Set Intersection
2019/3/1
Threshold private set intersection enables Alice and Bob who hold sets AA and BB of size nn to compute the intersection A∩BA∩B if the sets do not differ by more than some threshold parameter tt. In th...
