Proceedings ArticleDOI
Selective private function evaluation with applications to private statistics
TL;DR: Various approaches for constructing sublinear-communication SPFE protocols are presented, both for the general problem and for special cases of interest, which not only offer sublinear communication complexity, but are also practical in many scenarios.
Proceedings ArticleDOI
Black-box concurrent zero-knowledge requires \tilde {Ω} (logn) rounds
TL;DR: It is shown that any concurrent zero-knowledge protocol for a non-trivial language for a language outside $\BPP$, whose security is proven via black-box simulation, must use at least \tilde&OHgr;(log n) rounds of interaction.
Book ChapterDOI
Secure computation without authentication
TL;DR: This paper considers a completely unauthenticated setting, where all messages sent by the parties may be tampered with and modified by the adversary (without the honest parties being able to detect this fact), and constructs protocols for securely realizing any functionality in the stand-alone model, with no setup assumptions whatsoever.
Book ChapterDOI
Obfuscation of hyperplane membership
TL;DR: This work constructs an obfuscator for a more complex algebraic functionality: testing for membership in a hyperplane (of constant dimension), and proves the security of the obfuscator under a new strong variant of the Decisional Diffie-Hellman assumption.
