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...

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...

Oblivious-Transfer Amplification
Abstract. Oblivious transfer (OT) is a primitive of paramount importance in cryptography or, more precisely, two- and multi-party computation due to its universality. Unfortunately...

How Many Oblivious Transfers Are Needed for Secure Multiparty Computation?
Oblivious transfer (OT) is an essential building block for secure multiparty computation when there is no honest majority. In this setting, current protocols for n 3 parties requ...

Universally Composable Adaptive Oblivious Transfer
In an oblivious transfer (OT) protocol, a Sender with messages M1, . . . , MN and a Receiver with indices 1, . . . , k [1, N] interact in such a way that at the end the Receiver ...
