Security of Wireless Sensor Networks: Analysis of LEAP

It is of paramount importance to have a mechanism of alienating any suspicious node from a network before it leads to any damage. In this form of attack which is popularly referred to as camouflage attack the attacker first compromises an existing sensor node or inserts a malicious node with an intention of later using it. Once this node joins the network it will exchange and route messages with the other nodes as a legitimate node allowing the attacker to gather modify or inject data.
