Title:
Superposition Attack on OT Protocols
Authors: Ehsan Ebrahimi, Céline Chevalier, Marc Kaplan, Michele Minelli
Abstract:In this note, we study the security of oblivious transfer protocols in the presence of adversarial superposition queries. We define a security notion for the sender against a corrupted receiver that makes a superposition query. We present an oblivious transfer protocol that is secure against a quantum receiver restricted to a classical query but it is insecure when the receiver makes a quantum query.
