Oblivious Transfer Protocol for Confidentiality Query of Blockchain Data [PDF]
Jisuanji gongcheng, 2022 During the data storage and query of a blockchain, owing to the transparency and openness of the blockchain, all users of a network may obtain information regarding the inquirer;thus, confidential information regarding the inquirer may be exposed.This ...

Error-tolerant oblivious transfer in the noisy-storage model
Physical Review Research, 2023 The noisy-storage model of quantum cryptography allows for information-theoretically secure two-party computation based on the assumption that a cheating user has at most access to an imperfect, noisy quantum memory, whereas the honest users do not need ...

Universally Composable Oblivious Transfer with Low Communication
Applied Sciences, 2023 In this paper, a universally composable 1-out-of-N oblivious transfer protocol with low communication is built. This protocol obtained full simulation security based on the modulo learning with rounding (Mod-LWR) assumption.

PRX Quantum, 2023 Oblivious transfer (OT) is an important cryptographic primitive. Any multiparty computation can be realized with OT as building block. xor oblivious transfer (XOT) is a variant where the sender Alice has two bits and a receiver Bob obtains either the ...

ROTed: Random Oblivious Transfer for embedded devices
Transactions on Cryptographic Hardware and Embedded Systems, 2021 Oblivious Transfer (OT) is a fundamental primitive in cryptography, supporting protocols such as Multi-Party Computation and Private Set Intersection (PSI), that are used in applications like contact discovery, remote diagnosis and contact tracing.

On the Reversibility of Oblivious Transfer [PDF]
, 2007 A(2 1)-OT2, (one-out-of-two Bit Oblivious Transfer) is a technique by which a party S owning two secret bits b0, b1, can transfer one of them bc, to another party R, who chooses c. This is done in a way that does not release any bias about bt to R nor any bias about c to S.

The Simplest Protocol for Oblivious Transfer [PDF]
, 2015 Oblivious Transfer (OT) is the fundamental building block of cryptographic protocols. In this paper we describe the simplest and most efficient protocol for 1-out-of-n OT to date, which is obtained by tweaking the Diffie-Hellman key-exchange protocol. The protocol achieves UC-security against active and adaptive corruptions in the random oracle model ...

Incomplete quantum oblivious transfer protocols [PDF]
, 2021 1-2 oblivious transfer is a cryptographic primitive in which a sender, Alice, holds two bits and a receiver, Bob, obtains exactly one of them in such a way that Alice does not learn which bit Bob obtained.

Oblivious-Transfer Amplification [PDF]
, 2007 Oblivious transfer is a primitive of paramount importance in cryptography or, more precisely, two- and multi-party computation due to its universality. Unfortunately, oblivious transfer cannot be achieved in an unconditionally secure way for both parties from scratch.

Distributed Oblivious Transfer [PDF]
, 2000 This work describes distributed protocols for oblivious transfer, in which the role of the sender is divided between several servers, and a chooser (receiver) must contact a threshold of these servers in order to run the oblivious transfer protocol.
