Abstract: Implementations disclosed describe techniques to allow wireless devices to initially connect with randomized MAC addresses and send an encrypted permanent MAC for differentiated services. In one method, a first wireless device connects to an access point (AP) using a randomized MAC address. The first wireless device receives a request for a permanent MAC address from the AP. The first wireless device determines whether to send the permanent MAC address. Responsive to determining to send the permanent MAC address, the first wireless device encrypts the permanent MAC address to obtain an encrypted MAC address and sends a response to the request, including the encrypted MAC address, to the AP.

Abstract: A device may generate network profile data indicating a set of network parameters detected by the device. The device may encrypt the network profile data and may transmit the encrypted network profile data to a network device, such as a router, or a server. The router or server may analyze the encrypted network profile data to determine if the device is secure. The router of server may perform one or more security measures if the device is not secure.

Abstract: Devices, systems and methods use a first communication interface to connect with a local device via a first protocol and use a second communication interface to connect with a server via a second protocol. Embodiments relay secure communications between the local device and the server for authentication of the at least one local device by the server and responsive to authentication of the local device by the server, transmit information for storage in a secure memory of the authenticated local device.

Abstract: A method can include, by operation of a first wireless device, storing media access control (MAC) addresses for associated devices in first memory circuits of the first wireless device and receiving a wireless request protocol data unit (PDU) via wireless communication circuits. By operation of controller circuits of the first wireless device, determining if the MAC address of the request PDU matches a stored MAC address, and, in response to at least the MAC address of the request PDU matching a stored MAC address, ignoring the request PDU or not transmitting buffered data corresponding to a destination of the matching MAC address. Corresponding devices and systems are also disclosed.
