Latest Patents

Javier holds a patent for a groundbreaking invention titled "Time-coordinated address rotation." This patent encompasses devices, networks, systems, methods, and processes for rotating a MAC address of a device. The invention allows a device to negotiate a periodicity for address rotation of the MAC address associated with it. The device can receive a data frame and generate seed data based on that frame. It utilizes a shared secret key, a cryptographic hash function, and/or a cryptographically secure pseudorandom number generator to create the seed data. Additionally, the device determines timestamp data based on the periodicity or the time of reception of the data frame. By employing a pseudorandom function, the device can generate the MAC address after every rotation cycle, enhancing security. Upon waking from a power-saving mode, the device synchronizes with a network device to generate the next MAC address.
