Internet of Things (IoT) technology promises to bring new value
creation opportunities across all major industrial sectors. This will
yield industries to deploy more devices into their networks. A key
pillar to ensure the safety and security of the running services on
these devices is remote attestation. Unfortunately,existing solutions
fail to cope with the recent challenges raised by large IoT networks.
In particular, the heterogeneity of the devices used in the network
affects the performance of a remote attestation protocol. Another
challenge in these networks is their dynamic nature: More IoT
devices may be added gradually over time. This poses a problem in
terms of key management in remote attestation.
We propose FADIA, the first lightweight collaborative remote
attestation protocol that is designed with fairness in mind. FADIA
enables fair distribution of load/tasks on the attesting devices to
achieve better performance.We also leverage the Eschenauer-Gligor
scheme to enable efficient addition of devices to the network. We
implement our solution on heterogeneous embedded devices and
evaluate it in real scenarios. The evaluation shows that FADIA can
(i) increase the lifetime of a network by an order of magnitude and
(ii) decrease the remote attestation runtime by a factor of 1.6.
