WORMHOLE ATTACK DETECTING METHOD

摘要

PURPOSE: A method for detecting a wormhole attach link is provided to prevent the damage of a wormhole attack by detecting the wormhole attack in a wireless sensor network. CONSTITUTION: A gateway receives a routing path from sensor nodes. Based on the routing path, the gateway forms a neighbor node table. The gateway detects a wormhole attack link through the neighbor node table(S330), and transmits an authentication result for the routing path to a corresponding node. The gateway confirms the coincidence of the neighbor node table through the confirmation of 1 hop or N hop of each link.
