Keywords Sensitivity Recognition of Military Applications in Secure CRNs Environments

The proposed secure keywords recognition method to enhance the security of cognitive radio networks for the military application is a content awareness feature to classify transmission messages into High Data Sensitivity(HDS), Medium Data Sensitivity(MDS) and Low Data Sensitivity(LDS) using “Advanced Encryption Standard/Wi-Fi Protected Access 2”, “Frequency-hopping spread spectrum” (AES/WPA2,FHSS) to HDS, “Rivest-Shamir-Adleman (RSA)” to MDS and “Rivest Cipher (RC4)” to LDS for each message exchanged between CR nodes, respectively. All the simulation process is implemented in “OMNET++” simulation tool and visual (C) programming language. This paper will address the literature review, keywords sensitivity recognition and proposed security scheme for military application in CRNs.
