AUTHENTICATION AND AUTHORIZATION OF COGNITIVE RADIO DEVICES

摘要

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.

主权项

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 including at least a read-only memory portion for storing an identity and a private security key of the cognitive radio device, the memory unit further storing a list of the associated cognitive radio slave devices; a processor for:
generating a registration request message that includes an identifier and a location of the cognitive radio device, wherein the registration request message also includes a location and an identifier of a cognitive radio slave device to be authenticated;generating an authorization request message that includes an authentication signal decrypted from the encrypted authentication signal received from the cognitive radio slave device; andupon 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 that can be decoded by the cognitive radio slave device; andsending 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.
