Abstract
A method for defense against primary user emulation attacks in cognitive radio networks includes the steps of generating an advanced encryption standard (AES)-encrypted reference signal with a transmitter for transmitting to at least one receiver. The method also includes the steps of allowing a shared secret between the transmitter and the at least one receiver and regenerating the reference signal at the at least one receiver and using the regenerated reference signal to achieve accurate identification of authorized primary users as well as malicious users.
