U.S. Patent 10924283 was awarded to CISCO TECHNOLOGY, INC. on February 16, 2021 and is entitled “Dynamically-changing identity for IoT devices with blockchain validation.” The first named inventor is Carlos M. Pignataro of Cary, NC. The abstract contains an overview of the patent disclosure:

Techniques for use in generating a dynamically-changing IoT device identity with robust blockchain validation are provided. When entering a communication network, an IoT device performs a procedure for registration. The procedure includes communicating, in a transaction, data associated with the IoT device to a network device (e.g. a fog router). The data includes, amongst other data items, an identity for addressing communications to and from the IoT device. A transaction number associated with the transaction is received based on a blockchain registration of the transaction. An updated identity of the IoT device is then derived based on the transaction number. In one example, the updated identity of the IoT device may be derived by combining a static address of the IoT device and the transaction number. The steps may be repeated by the device for each one of a plurality of network registrations. Link to Full Patent
