A dynamic en-route scheme for filtering false data injection in wireless sensor networks

— In this paper, we propose a dynamic en-route filtering scheme for false data injection attacks in wireless sensor networks. In sensor networks, adversaries can inject false data reports containing bogus sensor readings or nonexistent events from compromised nodes. Such attacks may not only cause false alarms, but also drain out the limited energy of sensor nodes. Several existing schemes for filtering false reports either cannot deal with dynamic topology of sensor networks or have limited filtering capacity. In our scheme, a legitimate report is endorsed by multiple sensing nodes using their own authentication keys generated from one-way hash chains. Cluster head uses Hill Climbing approach to disseminate the authentication keys of sensing nodes to the forwarding nodes along multiple paths toward the base station. Hill Climbing guarantees that the forwarding nodes closer to a cluster hold more authentication keys for the cluster than those nodes farther from it do, hence, the n...
