  • Publication number: 20220417755
    Abstract: To improve adaptation of network infrastructure to address rotations performed by wireless client device, embodiments provide for an exchange of a stable machine identifier (SMI) between a network access device and an authentication service. Some embodiments define a new SMI attribute that is included in a authentication service access-request and/or access-accept message. When a network access device obtains an SMI for a particular wireless client device, the network access device passes the SMI to the authentication service. Similarly, if an authentication service obtains a SMI value for a wireless client device, this information is provided to a network access device.

  • Patent number: 11540116
    Abstract: A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.

  • Publication number: 20220386117
    Abstract: 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.
