*2.9.2. INSENSE - Intrusion-tolerant routing in wireless sensor networks*

INSENS (Intrusion-tolerant Routing in Wireless Sensor Networks)[66] constructs treestructured routing for wireless sensor networks (WSNs). It aims to tolerate damage caused by an intruder who has compromised deployed sensor nodes and is intent on injecting, modifying, or blocking packets. INSENS incorporates distributed lightweight security mechanisms, including one-way hash chains and nested keyed message authentication codes to defend against routing attacks such as wormhole attack. Adapting to WSN characteristics, the design of INSENS also pushes complexity away from resource-poor sensor nodes towards resource-rich base stations.
