ADDRESS RANDOMIZATION SCHEMES FOR MULTI-LINK DEVICES

Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

Address generation for networks

A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

DHCP resource optimization for randomized and changing MAC address

A wireless infrastructure that communicates with a DHCP server and a wireless client that rotates its MAC address performs a method including: upon receiving, from the wireless client, a first request with a first MAC address, creating a session context including the first MAC address and a stable identifier, and relaying the first request to the DHCP server; relaying, from the DHCP server to the wireless client, a first DHCP reply that includes an Internet Protocol (IP) address bound to the stable identifier; upon receiving, from the wireless client, a second request with the IP address and a second MAC address, merging the second MAC address and the IP address into the session context, and relaying, to the DHCP server, the second request including the stable identifier; and relaying, from the DHCP server to the wireless client, a second DHCP reply including the IP address bound to the stable identifier.

Client device based solution for handling MAC randomization

A system and method are provided for a network device for use with a client device having a hostname and a MAC address. The network device contains a memory that has a second hostname and a second MAC address stored within the memory. The second MAC address corresponds to the second hostname. The memory also contains a processor configured to execute instructions stored on the memory to cause the network device to: receive, from the client device, the hostname and the MAC address; determine whether the MAC address is randomized; provide an instruction to the client device to inform a user of the client device that the client device hostname is registered when the hostname matches the second hostname and the MAC address is randomized.

PROACTIVE NOTIFICATION OF WIRELESS CLIENT ADDRESS ROTATION
20230117067 · 2023-04-20 ·

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.

METHOD FOR MUTUAL RECOGNITION OR MUTUAL TRUST BETWEEN BLUETOOTH DEVICES
20220330029 · 2022-10-13 ·

A method includes receiving, by a first Bluetooth device, an identity resolving key (IRK) from a server, and generating a resolvable private address based on the IRK. The method further includes sending, by the first Bluetooth device, a broadcast message. The broadcast message includes the resolvable private address. The resolvable private address is successfully verified by a second Bluetooth device pre-configured with the IRK.
