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


In this paper, we show the first UC-secure multi-session OT protocol using tamper-proof hardware tokens. 1 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… (More)
