A Survey of Oblivious Transfer Protocol [PDF]
ACM Computing Surveys, 2022 Oblivious transfer (OT) protocol is an essential tool in cryptography that provides a wide range of applications such as secure multi-party computation, private information retrieval, private set intersection, contract signing, and privacy-preserving ...

2020 IEEE Information Theory Workshop (ITW), 2021 We consider oblivious transfer between one client and two non-colluding servers that store independent contents. The client requests one file from each server such that (i) the servers do not learn the file selection of the client, and (ii) the client ...

PriTAEC: Privacy-Preserving Task Assignment Based on Oblivious Transfer and Edge Computing in VANET
IEEE Transactions on Vehicular Technology, 2023Spatial crowdsourcing, e.g., Vehicular Ad-Hoc Network (VANET)-based spatial crowdsourcing, is a new distributed computing paradigm, in which task assignments highly rely on the wisdom of the crowdsourcing platform. However, with the increase in user data

On oblivious transfer capacity
2009 IEEE Information Theory Workshop on Networking and Information Theory, 2007The concept of oblivious transfer capacity has been recently introduced by Nascimento and Winter. We give an upper bound to this capacity, both for source and channel models, and prove that it is tight for a class of channels. For other cases, lower bounds are provided.

Decision-making plays an increasing important role in our digitalized society, and hence the need for trustworthy data. For example, in a traditional trading process, a trusted middle person generally helps to arbitrate any dispute between two or more ...

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. In this work, we consider a simulation based security notion that we call endemic security.

Oblivious Transfer for Privacy-Preserving in VANET’s Feature Matching
IEEE transactions on intelligent transportation systems (Print), 2021In the feature matching of some Vehicular Ad Hoc Network (VANET) technologies, users’ privacy disclosure issue has seriously threatened personal safety and caused considerable economic loss. In this paper, we proposed Oblivious Transfer (OT) protocol and

We consider the problem of designing an efficient oblivious transfer (OT) protocol that is provably secure in a concurrent setting, i.e., where many OT sessions may be running concurrently with their messages interleaved arbitrarily. Known OT protocols use zero-knowledge proofs, and no concurrent zero-knowledge proofs are known that use less than a ...

On Oblivious Transfer Capacity of Noisy Multiple Access Channel
International Symposium on Information TheoryThis work addresses the problem of Oblivious Transfer (OT) over a noisy Multiple Access Channel (MAC) involving two non-colluding senders and a single receiver.
