Abstract

A network server is provided. The network server includes at least one processor in communication with at least one memory device. The network server is programmed to receive an access request originating from a user device, perform an authentication process for connecting with the user device, transmit, to the user device, a request message for a media access control (MAC) address of the user device, receive, from the user device, a response message including the MAC address of the user device, and determine whether to grant the access request based on the MAC address of the user device.

Claims (26)

1. A network server comprising at least one processor in communication with at least one memory device, the network server being programmed to:

receive an access request originating from a user device;

perform an authentication process for connecting with the user device;

transmit, to the user device, a request message for a media access control (MAC) address of the user device;

receive, from the user device, a response message including an encrypted MAC address of the user device; and

determine whether to grant the access request based on decryption of the encrypted MAC address of the user device.

2. The network server of claim 1 , wherein the network server is further programmed to:

perform at least one of an integrity check or a confidentiality check of the MAC address; and

determine whether to grant the access request based on results of at least one of the integrity check and the confidentiality check.

3. The network server of claim 1 , wherein the network server is further programmed to transmit a cryptographic key in the request message for the MAC address of the user device.

4. The network server of claim 1 , wherein the network server is further programmed to decrypt the encrypted MAC address of the user device using a cryptographic key used to cipher an 802.11 layer.

5. The network server of claim 1 , wherein the network server is further programmed to transmit an access request success message if the determination is to grant the access request.

6. The network server of claim 1 , wherein the network server is further programmed to transmit an access request failure message if the determination is to deny the access request.

7. The network server of claim 6 , wherein the network server is further programmed to terminate service for the user device if the determination is to deny the access request.

8. The network server of claim 1 , wherein the access request includes a randomized MAC address from the user device.

9. The network server of claim 1 , wherein the access request is received from an access point in communication with the user device.

10. The network server of claim 1 , wherein the access request is received from a proxy server.

11. The network server of claim 1 , wherein the authentication process is an Extensible Authentication Protocol (EAP) authentication process.

12. The network server of claim 11 , wherein the request message for the MAC address of the user device includes an EAP type to specifically request the MAC address of the user device.

13. The network server of claim 12 , wherein the EAP type expands a listing of EAP types, and wherein the EAP type may be used in conjunction with EAP-TTLS (Tunneled Transport Layer Security), EAP-TLS (Transport Layer Security), EAP-GTP (Gateway Tunneling Protocol), and EAP-RP.

14. The network server of claim 1 , wherein the user device is one of a mobile device, a smart phone, a laptop, and a tablet.

15. The network server of claim 1 , wherein the access request is a request for access to a Wi-Fi network.

16. The network server of claim 1 , wherein the access request is a request for Internet access.

17. The network server of claim 1 , wherein the access request is a request for cellular access.

18. The network server of claim 1 , wherein the MAC address of the user device is one of a hardware address, a manufacturer provided address, universally administered address, and a locally administered address.

19. The network server of claim 1 , wherein the network server is in communication with at least one of a proxy server and an access point and wherein the proxy server or access point is programmed to retrieve the MAC address of the user device from the response message.
