    Abstract: A system includes processing circuitry; and a memory device including instructions embodied thereon, wherein the instructions, which when executed by the processing circuitry, configure the processing circuitry to perform operations comprising: accessing input data, at an aggregator node, the input data including sensor data from a plurality of sensor nodes, each sensor data having a respective signature; validating the sensor data by using respective cryptographic hash functions on the sensor data and evaluating the respective result using the respective signature; performing an aggregation function on the sensor data to produce aggregate data; executing a hash function on the aggregate data to produce a hash value for the aggregate data bundling the sensor data, respective signatures of the sensor data, aggregate data, and hash value for the aggregate data in a data structure; and exposing the data structure to subscriber nodes on the IoT network.
