The growth of the Internet has triggered tremendous opportunities for cooperative
computation, where people are jointly conducting computation tasks based on the private …

Cryptography, secret writing, is enjoying a scientific renaissance following the seminal
discovery in 1977 of public-key cryptography and applications in computers and …

We present CrypTFlow2, a cryptographic framework for secure inference over realistic Deep
Neural Networks (DNNs) using secure 2-party computation. CrypTFlow2 protocols are both …

Important decisions about people are increasingly made by algorithms: Votes are counted;
voter rolls are purged; financial aid decisions are made; taxpayers are chosen for audits; air …

We consider the problem of extending oblivious transfers: Given a small number of oblivious
transfers “for free,” can one implement a large number of oblivious transfers? Beaver has …

Protocols are given for allowing a “prover” to convince a “verifier” that the prover knows
some verifiable secret information, without allowing the verifier to learn anything about the …

A Private Information Retrieval (PIR) scheme is a protocol in which a user retrieves a record
from a database while hiding which from the database administrators. PIR can be achieved …

We describe efficient constructions for two oblivious twoparty computation problems: l-out-of-
N Oblivious Transfer &d 'Oblivious Poly&nial Evaluation. The oblivious polynomial …

We consider the question of protecting the privacy of customers buying digital goods. More
specifically, our goal is to allow a buyer to purchase digital goods from a vendor without …

This handbook provides an up-to-date compendium of fundamental computer science
topics, techniques, and applications. Along with updating and revising many of the existing …
