A Byzantine Resilient Secure Aggregation Protocol for Wireless Sensor Networks

To secure wireless sensor networks, a particularly challenging problem is how to feasibly deal with the internal attacks against the routing protocols, such as Byzantine attacks. In this paper, we proposed a secure routing a lightweight security protocol for detecting Byzantine attacks. In this paper, we develop: (1) an secure cluster header selection and clustering scheme that a source node can authenticate its CH and establish a session key on-demand; (2) a novel detection algorithm that can detect the byzantine aggregation attacks;(3) a byzantine resilient secure aggregation protocol (BRSA), in which a node selects its best route based on its accumulated trust on the nodes along the candidate routes; (4)a cost function that directly measures the cost of the increased trustworthiness and its impact on network performance. Simulations illuminate that BRSA is robust against byzantine aggregation.
