Title:
UC-Secure Multi-Session OT Using Tamper-Proof Hardware

Authors: Kaoru Kurosawa, Ro Nojima, Le Trieu Phong

Abstract:

In this paper, we show the first UC-secure {\it multi-session} OT protocol using tamper-proof hardware tokens. The sender and the receiver exchange tokens only at the beginning. Then these tokens are reused in arbitrarily many sessions of OT. The proposed scheme is UC-secure against static adversaries if the DDH assumption holds and a unique signature scheme exists. There exist a unique signature schemes under the Many DH assumption or under the DDHE assumption (in the standard model).
