1. A system comprising:
an Internet of Things (IoT) network comprising a plurality of IoT devices;
a network validator comprising:
a processor; and
non-transitory memory storing instructions that, when executed by the processor, cause the network validator to
generate, based on receipt of first information from a first IoT device identified on the IoT network, random cipher text associated with the first IoT device;
send, via the IoT network and to the first IoT device, the random cipher text;
send, via the IoT network and to the first IoT device, device cross reference information, wherein the device cross reference information corresponds to a different IoT device of the plurality of IoT devices on the IoT network;
initiate, by the plurality of IoT devices on the IoT network and based on the random cipher text and the device cross reference information of the first IoT device, generation of an integrity hash key associated with the plurality of IoT devices of the IoT network;
receive, via the IoT network, the integrity hash key; and
store, in a data repository, the integrity hash key.
