Abstract

AbstractWe consider weak oblivious transfer (OT) from strong one-way functions and the paradigm of transforming unconditionally secure protocols in Maurer’s bounded storage model into computational secure protocols in the random oracle model. Weak OT is secure against adversaries which have a quadratic resource gap to honest parties. We prove that the random oracle can be replaced with strong one-way functions in the OT protocol. We construct an OT protocol achieving quadratic security from strong one-way functions.KeywordsRandom OracleRandom StringRandom Oracle ModelOblivious TransferHonest PartyThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
