Encryption Algorithm for defending PUE Attack in Cognitive Radios

摘要

The Security is major problem in the Cognitive Radio communication. Several algorithms are designed and implemented for increase in the security of the Cognitive radio. To increase the High Security to overcome the Primary User Emulation Attacks, we proposed the new algorithm called Self Adaptive QUAD Encryption has been proposed. The proposed algorithm has been analyzed and simulated using the test beds designed using ARM CPU and simulated with the MATLAB. The proposed Algorithm has the unique feature in which the key is being generated based on the four important parameters such as RSSI, Distance, Power and ID which are adaptive to the environments and mode of the communication. The four tier encryption algorithm which is generated has been compared with the existing algorithms with the illustration of 70% of reduction of the PUE (Primary User Emulation) Attacks. The proposed algorithm has been tested with the experimental setup which has been designed. Also the Dynamic and Adaptive Four Tier Encryption finds its suitability for the real time CR Hardware which are first of its kind. This Encryption key finds its applications in Health care, banking and even in Consumer Electronics where the authentications of the primary users are necessary.
