An Improved Lower Bound on Oblivious Transfer Capacity via Interactive Erasure Emulation

International Symposium on Information Theory
We revisit the oblivious transfer (OT) capacities of noisy channels against the passive adversary, which have been identified only for a limited class of channels.

Computationally Secure Quantum Oblivious Transfer

Advanced Quantum Technologies, 2021
Oblivious transfer (OT) is one of the cornerstones of secure multiparty computation. It is clear that unconditionally secure OT is impossible. Any protocol for OT requires computational assumptions, such as number‐theoretic cryptographic assumptions or ...

Two-Round Oblivious Transfer from CDH or LPN

IACR Cryptology ePrint Archive, 2020
We show a new general approach for constructing maliciously-secure two-round oblivious transfer (OT). Specifically, we provide a generic sequence of transformations to upgrade a very basic notion of two-round OT, which we call elementary OT, to UC-secure

Reducing oblivious string transfer to universal oblivious transfer

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
It is shown that oblivious transfer of strings can be reduced to the weakest version of oblivious bit transfer, where the receiver can choose to obtain arbitrary (but incomplete) information about the pair of bits sent. This solves an open problem posed by Brassard and Crepeau (see Advances in Cryptography$EUROCRYPT' 97, LNCS, vol.1233, p.334-45 ...

Proxy oblivious transfer protocol

First International Conference on Availability, Reliability and Security (ARES'06), 2006
Oblivious transfer protocol is an important primitive in modern cryptography. Since its introduction, the subject has attracted a lot of attentions and has become the basis for realizing a broad class of cryptographic protocols, such as secret key exchange, contract signing, secure function evaluation, oblivious keyword search, etc. This work describes

Founding crytpography on oblivious transfer

Proceedings of the twentieth annual ACM symposium on Theory of computing - STOC '88, 1988
Suppose your netmail is being erratically censored by Captain Yossarian. Whenever you send a message, he censors each bit of the message with probability 1/2, replacing each censored bit by some reserved character. Well versed in such concepts as redundancy, this is no real problem to you.
