Abstract:

Motivated by applications like sensor, peer to peer networks there has been growing interest in monitoring large scale distributed systems. In these applications, source location anonymity is an attractive and critical security property. Most of prior works assumed a weak adversary model where the adversary sees only local network traffic, but here we consider source anonymity against a global eavesdropper. Attaining location unobservability under global attacker is very difficult and expensive to achieve, because sensor networks are very limited in resources. In this work we propose a distributed algorithm to mix real event traffic with carefully chosen dummy traffic to hide the real event traffic pattern. We assume that we have fixed amount of resources to send dummy traffic and we try to share it among sensors so as to maximize the degree of anonymity of the system. Through simulation, we illustrate that the proposed technique is efficient in protecting location information from the eavesdropper.
