Abstract
A wireless local area network authenticates access by a user's device utilizing an authentication key provisioned in another of the user's devices. The network transmits a challenge to the non-provisioned device. The non-provisioned device forwards the challenge to the provisioned device across a wire-based or wireless interface connecting the two devices, such as a BLUETOOTH network link. The provisioned device calculates a response using the authentication key, and forwards the response to the non-provisioned device. The non-provisioned device then transmits the response to the wireless local area network for authentication.
Claims34
A method of authenticating a wireless device for accessing a first wireless network challenging said device, comprising:
- receiving an authentication challenge from said first wireless network at a first wireless device;
- forwarding said authentication challenge from said first wireless device to a second wireless device storing an authentication key;
- calculating an authentication response based on said authentication key at said second wireless device;
- forwarding said authentication response from said second wireless device to said first wireless device;
- and
- transmitting said authentication response from said first wireless device to said first wireless network.
20 The method of claim 19 further comprising:
- sending an authentication result from the second wireless network to the first wireless network;
- and
- providing or denying access for the first wireless device to the first wireless network based on said authentication result.
A wireless device comprising:
- a first interface to communicate with a wireless network;
- a second interface to communicate with a provisioned wireless device having an authentication key used to access the wireless network;
- a microprocessor connected to said first and second interfaces and programmed to:
- forward an authentication challenge received from the wireless network via said first interface to the provisioned wireless device via said second interface;
- receive an authentication response from the provisioned wireless device via said second interface;
- and
- forward the authentication response via said first interface to the wireless network.
A wireless device having an authentication key used to access a wireless network comprising:
- an interface to communicate with a non-provisioned wireless device;
- an authentication unit connected to said interface and having a memory for storing the authentication key and a processor for performing calculations using said authentication key, said authentication unit being operative to:
- receive an authentication challenge via said interface from the non-provisioned wireless device attempting to access the wireless network,
- compute an authentication response using the authentication challenge and the authentication key;
- and
- forward the authentication response via the interface to the non-provisioned wireless device to be used by the non-provisioned wireless device to access the wireless network.
