We formalize in this work a model for node capture attack in a secure wireless sensor networks (WSNs). The adversary starts by overhearing exchanged messages to learn about the network because of all data transmissions nature (all in the air). Then, it has the physical access to the node, and with appropriate tools, it can read the secret information (like keys, programs, etc.) stored in the victim node memory. After that, we show how it removes that compromised node from the network and redeploys them for performing diverse attacks. Finally, we discuss a proposition of an intrusion detection system (IDS) to avoid this type of attacks.
