Abstract :
False data injection (FDI) is great threat to wireless sensor networks. Public key cryptography (PKC) is desirable to locate source nodes that are launching false data injection attacks. Because PKC is expensive to sensor nodes, they could only afford a small number of these operations. In this paper, a hierarchical traceback mechanism is proposed. A sensor field is divided into some levels, and in every step of traceback process the source node is located in a smaller level. The performance of the mechanism is thoroughly evaluated, and only O(logn) packets would be verified in order to locate a source node.
