Jaap-Henk Hoepman, (KU Nijmegen, Department of Computer Science), 
The ephemeral pairing problem. 

Abstract: In wireless ad-hoc broadcast networks, the pairing problem
consists of establishing a (long-term) connection between two specific
physical nodes in the network that do not yet know each other. We
focus on the ephemeral version of this problem. Ephemeral pairings
occur, for example, when electronic business cards are exchanged
between two people that meet, or when one pays at a check-out using a
wireless wallet. This problem can, in more abstract terms, be phrased
as an ephemeral key exchange problem: given a low bandwidth authentic
(or private) communication channel between two nodes, and a high
bandwidth broadcast channel, can we establish a high-entropy shared
secret session key between the two nodes without relying on any a
priori shared secret information. Apart from introducing this new
problem, we present several ephemeral key exchange protocols, both for
the case of authentic channels as well as for the case of private
channels. This paper will also be presented at the Financial
Cryptography 2004 Conference.
