Protocols for Authenticated Oblivious Transfer
Mehrad Jaberi and Hamid Mala
Abstract
Oblivious transfer (OT) is a basic building block in many cryptographic protocols. In this paper, we exploit some well-known authenticated Diffie-Hellman-based key exchange protocols to build three authenticated 1-out-of-2 oblivious transfers. We show that our proposed protocols are secure in the semi-honest model. We also compare our schemes with three similar 1-out-of-2 OT protocols and show that authentication in our schemes costs only up to either two more exponentiations or one message signing, compared to those with no authentication.
