Quantum XOR and Rabin oblivious transfer [PDF]
, 2023 Oblivious transfer is a cryptographic primitive involving two non-trusting communicating parties. Since it is a basic building block for any two-party computation, it is a quite powerful and important cryptographic functionality and thus topic of ...

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 ...

Oblivious Transfer from Zero-Knowledge Proofs, or How to Achieve Round-Optimal Quantum Oblivious Transfer and Zero-Knowledge Proofs on Quantum States [PDF]
IACR Cryptology ePrint Archive, 2023 We provide a generic construction to turn any classical Zero-Knowledge (ZK) protocol into a composable (quantum) oblivious transfer (OT) protocol, mostly lifting the round-complexity properties and security guarantees (plain-model/statistical security ...

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.

A New Framework for Quantum Oblivious Transfer [PDF]
IACR Cryptology ePrint Archive, 2022 We present a new template for building oblivious transfer from quantum information that we call the"fixed basis"framework. Our framework departs from prior work (eg., Crepeau and Kilian, FOCS '88) by fixing the correct choice of measurement basis used by

Quantum and classical oblivious transfer: A comparative analysis
IET Quantum Communication, 2021 Secure multiparty computation has the potential to be a disruptive technique in the realm of data analysis and computation. It enables several parties to compute virtually any function while preserving the privacy of their inputs.

Information-Theoretically Secure String Commitments Based on Packet Reordering Channels
IEEE Access, 2021 Realizing fundamental cryptographic primitives with unconditional security is a central topic in information-theoretic cryptography. These primitives can be realized based on physical assumptions, such as the existence of noisy channels, an upper bound ...

Endemic Oblivious Transfer [PDF]
, 2021 Oblivious Transfer has played a crucial role in the design of secure multi party computation. Nevertheless, there are not many practical solutions that achieve simulation based security and at the same time instantiable based on different assumptions ...
