Efficient Oblivious Transfer Protocols
"... 1 Introduction Oblivious Transfer (OT) protocols allow one party, the sender, to transmit part of its inputs to another party, the chooser, in a manner that protects both of them: the sender is assured that the chooser does not receive more information than it is entitled, while the chooser is assur ..."

Oblivious Transfer Protocols
"... Abstract. Oblivious Transfer (OT) is an important cryptographic tool, which has found its usage in many crypto protocols, such as Secure Multiparty Computations [9], Certified E-mail [2] and Simultaneous Contract Signing [20]. In this paper, we propose three k-out-of-n OT (OT n k) protocols based on ..."

A Secure Oblivious Transfer Protocol from Indistinguishing
"... Abstract. We proposed a new secure oblivious transfer protocol from indistinguishability obfuscation in this paper. Our main technical tool is the candidate indistinguishability obfuscation introduced in [1] and a dual-mode cryptosystem proposed in [2]. Following their steps, we presents a new k-out ..."

An Oblivious Transfer Protocol with Log-Squared Communication
, 2004
"... We propose a -computationally-private information retrieval protocol (CPIR), based on the Damgard-Jurik public-key cryptosystem from PKC 2001, with total communication (log N) k. We show how to extend it to a four-round N)k. These protocols are, respectively, the first -CPIR ..."

New communication-efficient oblivious transfer protocols based on pairings
- ISC 2008: 11th International Conference on Information Security, volume 5222 of Lecture Notes in Computer Science
, 2008
"... Abstract. We construct two simple families of two-message (n, 1)-oblivious transfer protocols based on degree-t homomorphic cryptosystems with the communication of respectively 1 + ⌈n/t ⌉ and 3 + ⌈n/(t + 1)⌉ ciphertexts. The construction of both families relies on efficient cryptocomputable conditio ..."

Quantum oblivious transfer protocols based on EPR states
, 1995
"... We describe efficient protocols for quantum oblivious transfer and for one-out-of-two quantum oblivious transfer. These protocols, which can be implemented with present technology, are secure against general attacks as long as the cheater can not store the bit for an arbitrarily long period of time. ..."

• ARTICLES • Efficient k-out-of-n oblivious transfer protocol
"... Abstract: A new k-out-of-n oblivious transfer protocol is presented in this paper. The communication cost of our scheme are n+1 messages of sender to receiver and k messages from the receiver to sender. To the best knowledge of the authors, the communication complexity of our scheme is the least. Al ..."

Using probabilistic I/O automata to analyze an oblivious transfer protocol
, 2005
"... We demonstrate how to carry out cryptographic security analysis of distributed protocols within the Probabilistic I/O Automata framework of Lynch, Segala, and Vaandrager. This framework provides tools for arguing rigorously about the concurrency and scheduling aspects of protocols, and about protoco ..."

k out of n Oblivious Transfer Protocols from Bilinear Pairings
"... Abstract—Two non-interactive three parties k out of n oblivious transfer protocols knOT (where 0<k<n) from bilinear pairings are proposed in this paper. In these protocols, a sender can obliviously transfer n messages to a receiver without communication with him/her. The public keys that a sen ..."
