Abstract

A network association apparatus includes identification information and an authorization credential associated with a specific client device or service to be connected to a wireless network. The apparatus is configured to automatically provide the identification information and the authorization credential to a host device of a wireless network in a secure fashion when brought into close proximity to or physically connected with the host of the wireless network. The apparatus may comprise an RFID tag.

Claims

1. An apparatus, comprising:

a memory including,

identification information for identifying a client device when connecting the client device to a wireless network, wherein the apparatus is physically separate from the client device, and

an authorization credential associated with the client device, wherein the identification information and the authorization credential are globally unique to the client device on the wireless network; and

a controller coupled to the memory and configured to;

receive the identification information from the client device; and

automatically provide the identification information and the authorization credential to a host device of the wireless network upon becoming communicatively connected with the host device,

wherein the host device is configured to;

automatically associate the client device with the wireless network using the identification information and the authorization credential, and

automatically disassociate the client device with the wireless network when the apparatus is detected to be no longer in close proximity to or physically connected to the host device,

wherein the apparatus is one of a near-field radio frequency identification (RFID) tag, a universal serial bus (USB) drive manufactured with write-protected encrypted bits, an optical disk with manufactured keys, or a secure digital (SD) memory card with digital rights management (DRM) features.

2. The apparatus of claim 1, wherein the identification information includes a media access control (MAC) address of the client device.

3. The apparatus of claim 1, further comprising a visual identifier disposed on an outer surface of the apparatus.

4. The apparatus of claim 3, wherein the visual identifier comprises at least one of a logo of a company associated with the client device, an icon that represents the client device, a serial number associated with the client device, or a bar code that uniquely identifies the client device.

5. The apparatus of claim 1, wherein the apparatus becomes communicatively connected to the host device when the apparatus at least one of (i) comes within close proximity of the host device and (ii) is physically connected to the host device such that communication to the host device is established.

6. The apparatus of claim 1, wherein the memory further includes a write-protected region and the identification information and the authorization credential are disposed in the write-protected region.

7. The apparatus of claim 1, wherein the memory further includes a writable region configured to store information from the host device of the wireless network.

8. The apparatus of claim 1, wherein the apparatus is a near-field RFID tag and is configured to automatically provide the identification information and the authorization credential to the host device of the wireless network only when in close proximity to the host device of the wireless network.

9. A system, comprising:

a network association apparatus comprising;

a memory comprising;

identification information for identifying a client device when connecting the client device to a wireless network, wherein the network association apparatus is physically separate from the client device, and

an authorization credential associated with the client device, wherein the identification information and the authorization credential are globally unique to the client device on the wireless network; and

a controller coupled to the memory and configured to;

receive the identification information and the authorization credential from the client device; and

provide the identification information and the authorization credential to a host device of the wireless network upon becoming communicatively connected with the host device;

wherein the network association apparatus is one of a near-field radio frequency identification (RFID) tag, a universal serial bus (USB) drive manufactured with write-protected encrypted bits, an optical disk with manufactured keys, or a secure digital (SD) memory card with digital rights management (DRM) features; and

the host device of the wireless network configured to;

automatically obtain the identification information and the authorization credential from the network association apparatus,

automatically associate the client device with the wireless network using the identification information and the authorization credential, and

automatically disassociate the client device with the wireless network when the network association apparatus is detected to be no longer in close proximity to or physically connected to the host device.

10. The system of claim 9, wherein the network association apparatus is configured to automatically provide the identification information and the authorization credential to the host device only when the network association apparatus come within close proximity to or is physically connected to the host device such that communication to the host device is established.

11. The system of claim 10, wherein the network association apparatus is a near-field RFID tag and is configured to automatically provide the identification information and the authorization credential to a host device of the wireless network only when presented to the host device of the wireless network in a prescribed orientation with respect to the host device.

12. The system of claim 9, wherein the identification information includes a media access control (MAC) address of the client device.

13. The system of claim 9, wherein the network association apparatus is configured to be mounted on the host device.

14. A method, comprising:

detecting an apparatus associated with a client device becoming communicatively connected with a host device, wherein the apparatus is physically separate from the client device and is one of a near-field radio frequency identification (RFID) tag, a universal serial bus (USB) drive manufactured with write-protected encrypted bits, an optical disk with manufactured keys, or a secure digital (SD) memory card with digital rights management (DRM) features;

automatically receiving, at the host device of a wireless network, identification information and an authorization credential associated with the client device from the apparatus, wherein the identification information and the authorization credential are globally unique to the client device on the wireless network;

receiving at the host device a registration request from the client device;

upon receiving the registration request, connecting the client device to the wireless network based on the identification information and the authorization credential, wherein the identification information identifies the client device;

detecting that the apparatus is no longer in close proximity to or physically connected to the host device; and

in response to detecting that the apparatus is no longer present, automatically terminating the connection of the client device to the wireless network.
