Abstract

A method of authentication and authorization of cognitive radio devices comprises generating a registration request message; sending the registration request to a spectrum manager; receiving a registration response message from the spectrum manager; generating an authorization request message; upon receiving of an authorization response message, generating a verification response message; and sending the verification response message to the cognitive radio device to be authenticated, such that the cognitive radio device is authenticated and authorized to communicate on channels designated in the verification response message.

Claims

1. A cognitive radio device for authenticating and authorizing a plurality of cognitive radio slave devices operable in a wireless network, comprising:

a memory unit for storing a list of the associated cognitive radio slave devices;

a processor for;

generating a registration request message that includes an identifier of a cognitive radio slave device to be authenticated;

generating an authorization request message that includes a decrypted authentication signal received from the cognitive radio slave device; and

upon receiving an authorization response message from a spectrum manager, generating a verification response message that includes at least a list of available channels and transmission power limits set for the cognitive radio slave device; and

a communication module for;

sending the registration request message to the spectrum manager;

receiving a registration response message that includes an encrypted authentication signal to be forwarded for decoding to the cognitive radio slave device; and

sending the verification response message to the cognitive radio slave device, such that the cognitive radio slave device is authenticated and authorized to communicate on channels designated in the verification response message.

2. The device of claim 1, wherein the registration request message includes a location and an identifier of each of the associated cognitive radio slave devices, and the authorization request message includes a decrypted authentication signal of each of the associated cognitive radio slave devices.

3. The device of claim 1, wherein the wireless network is at least one of an Ecma 392 based wireless network, an IEEE 802.22 based wireless network, and an IEEE 802.11 based wireless network.

4. The device of claim 1, wherein the registration request message further includes an identifier and a location of the cognitive radio device.
