Abstract
Devices and methods are provided for implementing a shared radio frequency spectrum allocation system. Access points and end user devices in an Authorized Shared Access System are allowed to access a channel of the shared radio frequency spectrum managed by an Authorized Shared Access System controller. Access points provide a communication, or frequency, channel over which similarly configured end user devices obtain access to data networks for client devices. Secure access to the allocated channel of the shared radio frequency spectrum is provided, thereby preventing rogue devices from gaining uncontrolled, or unauthorized, access to a channel of the shared radio frequency spectrum that may result in interference with other users of the channel including higher priority users. A secure synthesizer and secure encrypted tuning control words uniquely and securely control local channel usage.
