Modeling of RF security system using smart antennas

This work establishes a state-of-the-art protective measure on how the smart antennas can be used effectively to curtail the activities of hackers/intruders on radio frequency signals. Hackers can scan confidential information/data belonging to organization, law enforcement and even interception of radio frequencies signals to the public usage. In this analysis, three antenna elements array have been used. (i) The first antenna elements was used for the transmission/reception (transceiver) of radio frequency signal. This transceiver also acts for remotely transmitting information signal virtual to mobile station. (ii) The two antenna elements at the mobile station is being used as descrambler against any illegitimate activities. Some of the imperative securities challenges covered in this work are secrecy, authentication, privacy, and attacks. In the choice of frequency bandwidth for the transmission of signal, IEEE standard 802.11 designed for wireless local area network system had been maintained.
