Supersingular Isogeny Oblivious Transfer (SIOT)

Paulo Barreto and Anderson Nascimento Glaucio Oliveira and Waldyr Benits

Abstract: In this paper we present an Oblivious Transfer (OT) protocol that combines an OT scheme together with the Supersingular Isogeny Diffie-Hellman (SIDH) primitive. Our proposal is a candidate for post-quantum secure OT and demonstrates that SIDH naturally supports OT functionality. We consider the protocol in the simplest configuration and analyze the protocol to verify its security.
