Publication number: 20240089731Abstract: Rotation of a wireless client device address is based on an encryption key and a nonce value. Key information and nonce value information are shared between a wireless client device and a network infrastructure component over a secure communication channel. The wireless client device encrypts the nonce value using the key information and encodes the encrypted value as a device address. The wireless client device then identifies itself via a source address value in a message transmitted over a wireless network. Upon receiving the message, the network infrastructure component decrypts information derived from the source address value and compares the resulting data to the nonce value. If a match is identified, the network infrastructure identifies the wireless client device as a source of the message. In some embodiments, the nonce value is updated with each rotation to provide for improved entropy of generated device addresses.Type: ApplicationFiled: November 27, 2023Publication date: March 14, 2024Inventors: Jerome Henry, Stephen Michael Orr, Robert E.
