Quantum Oblivious Transfer: A Short Review [PDF]
Entropy, 2022 Quantum cryptography is the field of cryptography that explores the quantum properties of matter. Generally, it aims to develop primitives beyond the reach of classical cryptography and to improve existing classical implementations.

Quantum Rabin oblivious transfer using two pure states [PDF]
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 ...

On the Composability of Statistically Secure Random Oblivious Transfer [PDF]
Entropy, 2020 We show that random oblivious transfer protocols that are statistically secure according to a definition based on a list of information-theoretical properties are also statistically universally composable.

Error-tolerant oblivious transfer in the noisy-storage model [PDF]
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 ...

Physical implementation of oblivious transfer using optical correlated randomness [PDF]
Scientific Reports, 2017 We demonstrate physical implementation of information-theoretic secure oblivious transfer based on bounded observability using optical correlated randomness in semiconductor lasers driven by common random light broadcast over optical fibers.

Noninteractive xor Quantum Oblivious Transfer: Optimal Protocols and Their Experimental Implementations [PDF]
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 ...

All-or-nothing oblivious transfer based on the quantum one-way function
Frontiers in Physics, 2022 Oblivious transfer (OT) is one of the keystones of secure multi-party computation. It is generally believed that unconditionally secure OT is impossible.

An MLWE-Based Cut-and-Choose Oblivious Transfer Protocol [PDF]
EntropyThe existing lattice-based cut-and-choose oblivious transfer protocol is constructed based on the learning-with-errors (LWE) problem, which generally has the problem of inefficiency.

Device-independent oblivious transfer from the bounded-quantum-storage-model and computational assumptions [PDF]
New Journal of Physics, 2023 We present a device-independent protocol for oblivious transfer (DIOT) and analyse its security under the assumption that the receiver’s quantum storage is bounded during protocol execution and that the device behaves independently and identically in ...
