Supersingular Isogeny Oblivious Transfer (SIOT) (1805.06589v2)
Published 17 May 2018 in cs.CR
Abstract: We present an oblivious transfer (OT) protocol that combines the OT scheme of Chou and Orlandi together with thesupersingular isogeny Diffie-HeLLMan (SIDH) primitive of De Feo, Jao, and Pl^ut. Our construction is a candidate for post-quantum secure OT and demonstrates that SIDH naturally supports OT functionality. We consider the protocol in the simplest configuration of $\binom{2}{1}$-OT and analyze the protocol to verify its security.
