Generalized Non-Interactive Oblivious Transfer Using Count-Limited Objects with Applications to Secure Mobile Agents
Oblivious transfer (OT) is a fundamental primitive used in many cryptographic protocols, including general secure function evaluation (SFE) protocols. However, interaction is a pri...

Efficient Fully-Simulatable Oblivious Transfer
Oblivious transfer, first introduced by Rabin, is one of the basic building blocks of cryptographic protocols. In an oblivious transfer (or more exactly, in its 1-out-of-2 variant...

Committed Oblivious Transfer and Private Multi-Party Computation
Abstract. In this paper we present an eficient protocol for “Committed Oblivious Transfer” to perform oblivious transfer on committed bits: suppose Alice is committed to bits 0...

Oblivious Transfers and Privacy Amplification
Oblivious transfer (OT) is an important primitive in cryptography. In chosen one-out-of-two string OT, a sender offers two strings, one of which the other party, called the receive...

Oblivious Transfer Is Symmetric
We show that oblivious transfer of bits from A to B can be obtained from a single instance of the same primitive from B to A. Our reduction is perfect and shows that oblivious tran...

Optimal Reductions Between Oblivious Transfers Using Interactive Hashing
Abstract. We present an asymptotically optimal reduction of one-outof-two String Oblivious Transfer to one-out-of-two Bit Oblivious Transfer using Interactive Hashing in conjunctio...

An Efficient Protocol for Secure Two-Party Computation in the Presence of Malicious Adversaries
We show an efficient secure two-party protocol, based on Yao's construction, which provides security against malicious adversaries. Yao's original protocol is only secur...

Fair Computation of General Functions in Presence of Immoral Majority
This paper describes a method for n players, a majority of which may be faulty, to compute correctly, privately, and fairly any computable function f(Xl, ...,x,) where xi is the i...

On the (Im)possibility of Basing Oblivious Transfer and Bit Commitment on Weakened Security Assumptions
We consider the problem of basing Oblivious Transfer (OT) and Bit Commitment (BC), with information theoretic security, on seemingly weaker primitives. We introduce a general model...

Conditional Oblivious Transfer and Timed-Release Encryption
Abstract. We consider the problem of sending messages into the future." Previous constructions for this task were either based on heuristic assumptions or did not provide anon...
