In this paper, the authors study the Denial-of-Service (DoS) attack and physical layer attack on secondary users in a cognitive radio network by Primary User Emulation (PUE). Most approaches in the literature on Primary User Emulation Attacks (PUEAs) discuss mechanisms to deal with the attacks but not analytical models. This paper considers physical layer attacks, Primary User Emulation Attacks (PUEAs) and routing attacks in cognitive radio networks operating in the white spaces of the Digital TV (DTV) band. They propose a reliable ECC scheme, in which the network validates the nodes by verifying the authentication reference signals. The proposed model uses digital authentication to validate the receiver node.
