Supersingular Isogeny Oblivious Transfer (SIOT)

Paulo Barreto, 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.

Note: ((((((We have identified some problems with the security proof of our protocol and are working to update it.)))))
