Proxy oblivious transfer protocol
First International Conference on Availability, Reliability and Security (ARES'06), 2006Oblivious transfer protocol is an important primitive in modern cryptography. Since its introduction, the subject has attracted a lot of attentions and has become the basis for realizing a broad class of cryptographic protocols, such as secret key exchange, contract signing, secure function evaluation, oblivious keyword search, etc. This work describes

Reducing oblivious string transfer to universal oblivious transfer
2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002It is shown that oblivious transfer of strings can be reduced to the weakest version of oblivious bit transfer, where the receiver can choose to obtain arbitrary (but incomplete) information about the pair of bits sent. This solves an open problem posed by Brassard and Crepeau (see Advances in Cryptography$EUROCRYPT' 97, LNCS, vol.1233, p.334-45 ...

Oblivious Transfer in Incomplete Networks
2018Secure message transmission and Byzantine agreement have been studied extensively in incomplete networks. However, information theoretically secure multiparty computation (MPC) in incomplete networks is less well understood. In this paper, we characterize the conditions under which a pair of parties can compute oblivious transfer (OT) information ...

Unconditionally-Secure Oblivious Transfer
2001This paper investigates oblivious transfer protocol based on privacy amplification that uses Renyi entropy of order a for any 1 < a < 2, the conditions under which the protocol is secure are given. In protocol it makes no assumptions about receiver's computing power, so under the given conditions the protocol is unconditionally-secure.

Practical Oblivious Transfer Protocols
2007We consider 1-out-N Oblivious Transfer (OT) for strings. Oblivious Transfer is a primitive used in a variety of cryptographic protocols and applications (e.g. [11, 1, 10, 17, 12, 13]).We present a new highly efficient two-pass (one-round) protocol for 1- out-N OT.
