SECURITY OF COGNITIVE RADIO USING SMART RADIO CHANNEL CHANGE PROTOCOL

摘要

Although a lot of progress has been made on various fronts for the cognitive radio security still remains a prime issue. The cognitive radio paradigm introduces entirely new classes of security threats and challenges and providing strong security may prove to be the most difficult aspect of making cognitive radio a long-term commercially-viable concept. In our project we firstly allocate frequencies to the primary and the secondary user. Next we create an attacker who possesses a parameter which will be easily distinguishable from the primary and secondary user. When a primary user requests the channel that is being used by the secondary user the secondary user immediately switches over to another channel and hands over the current channel to the primary user.
