Random Beacon for Privacy and Group Security

Aleksi Saarela, Jan-Erik Ekberg, Kaisa Nyberg, Random Beacon for Privacy and Group Security. In: WIMOB \'08. IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2008. , 514-519, 2008.

Abstract:

Most contemporary security mechanisms and protocols include exchange of random or time-variant nonces as an essential means of protection against replay and other threats or as a seed for randomness. In many cases, it would be beneficial to have such nonces available from a trusted common source, such as a satellite. The goal of this paper is to present a protocol by which a loosely connected network of devices can agree on a common piece of randomness, and show how it can be applied to improve efficiency of a privacy protection system and group session key exchange for PAN/LAN devices.
