Abstract

We consider ad hoc wireless networks and adversaries that try to gain control over the network by Sybil attacks, that is by emulating more physical nodes that are really under his control.We present the first defense method that works for the case when the adversary controls more than one device and these devices have some prior agreement on strategy executed and share preloaded secrets.
