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.

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.

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.

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.

Efficient oblivious transfer with membership verification
International Journal of Distributed Sensor Networks, 2019 In this article, we introduce a new concept of oblivious transfer with membership verification that allows any legitimate group users to obtain services from a service provider in an oblivious manner.

Continuous-variable protocol for oblivious transfer in the noisy-storage model [PDF]
Nature Communications, 2018 Oblivious transfer is a standard primitive for cryptography between two parties which do not trust each other. Here, the authors propose a continuous-variable protocol which is secure against a dishonest party with bounded quantum storage capacity, and ...

Oblivious Transfer Based on NTRUEncrypt
IEEE Access, 2018 Oblivious transfer (OT) is the most fundamental process in cryptosystems and serves as the basic building block for implementing protocols, such as the secure multi-party computation and the fair electronic contract.
