Hoepman studied the ephemeral pairing problem by regarding the human operator of the devices as a messenger in an authenticated and/or private low-bandwidth channel between the nodes. Here we study the pairing problem with user interaction in which the operator can participate by doing extra (simple) computations.Authenticationpairingkey exchangeNCCR-MICSNCCR-MICS/CL3text::conference output::conference proceedings::conference paper
