Oblivious Transfer Is Symmetric [PDF]
, 2006 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 transfer is in fact a symmetric functionality. This solves an open problem posed by Crepeau and Santha in 1991.

Oblivious Transfer and Quantum Channels [PDF]
2006 IEEE Information Theory Workshop, 2006 We show that oblivious transfer can be seen as the classical analogue to a quantum channel in the same sense as non-local boxes are for maximally entangled qubits.

Quantum Rabin oblivious transfer using two pure states
Physical Review ResearchOblivious transfer between two untrusting parties is an important primitive in cryptography. There are different variants of oblivious transfer. In Rabin oblivious transfer, the sender Alice holds a bit, and the receiver Bob either obtains the bit, or ...

Oblivious Transfer Is in MiniQCrypt [PDF]
, 2021 MiniQCrypt is a world where quantum-secure one-way functions exist, and quantum communication is possible. We construct an oblivious transfer (OT) protocol in MiniQCrypt that achieves simulation-security in the plain model against malicious quantum polynomial-time adversaries, building on the foundational work of Bennett, Brassard, Crépeau and ...

A device-independent protocol for XOR oblivious transfer [PDF]
Quantum, 2022 Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob's desired function choice and Bob should not learn any more than what is logically implied by the ...

Generation and Distribution of Quantum Oblivious Keys for Secure Multiparty Computation
Applied Sciences, 2020 The oblivious transfer primitive is sufficient to implement secure multiparty computation. However, secure multiparty computation based on public-key cryptography is limited by the security and efficiency of the oblivious transfer implementation.
