Random Beacon for Privacy and Group Security

Download users.utu.fi

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.
