A Functional Relationship Based Attestation Scheme for Detecting Compromised Nodes in Large IoT Networks

Abstract: Despite memory traverse is commonly used for attestation, this approach could not feasibly work for an IoT network that requires scalable and sustainable operations. To overcome this limitation, we propose a functional relationship based attestation scheme, which verifies the integrity of battery-powered devices by analyzing the consistency among neighbors, where a consistent edge between two nodes is given if outputs of the same functions at both nodes are equal to each other. Efficiency of the proposed method is demonstrated in terms of attestation termination and detection speed.
