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.
