Abstract: A method of verifying integrity of an Internet of Things (IoT) system including a hub device and a plurality of end-node devices includes: determining, by the hub device, a root device among the plurality of end-node devices; receiving, by the hub device, from the root device at least one root message authentication code generated based on a result of verifying integrity of a sub-tree of the root device, wherein the sub-tree of the root device comprises a subset of the plurality of end-node devices subordinate to the root device; and verifying, by the hub device, the at least one root message authentication code.
