Scalable Multi-party Private Set-Intersection
In this work we study the problem of private set-intersection in the multi-party setting and design two protocols with the following improvements compared to prior work. First, our protocols are designed in the so-called star network topology, where a designated party communicates with everyone else, and take a new approach of leveraging the 2PC protocol of [FNP04]. This approach minimizes the ...
متن کاملFast and Private Computation of Cardinality of Set Intersection and Union
With massive amounts of electronic information stored, transferred, and shared every day, legitimate needs for sensitive information must be reconciled with natural privacy concerns. This motivates various cryptographic techniques for privacy-preserving information sharing, such as Private Set Intersection (PSI) and Private Set Union (PSU). Such techniques involve two parties – client and serve...

15 صفحه اولPrivate Two-Party Set Intersection Protocol in Rational Model
Many data mining algorithms use privacy preserving set intersection operations. Private set operations have considered semi-honest and malicious adversarial models in cryptographic settings. Protocols in semi-honest model, requiring light computations, provide weak security. Protocols in malicious model guarantee strong security at the price of expensive computations like homomorphic encryption...
متن کاملOn the Security of O-PSI a Delegated Private Set Intersection on Outsourced Datasets (Extended Version)
In recent years, determining the common information privately and efficiently between two mutually mistrusting parties have become an important issue in social networks. Many Private set intersection (PSI) protocols have been introduced to address this issue. By applying these protocols, two parties can compute the intersection between their sets without disclosing any information about compone...
