A Security Scheme of MISO Broadband System

To achieve the perfect physical layer security of the Multiple-Input Single-Output (MISO) broadband systems with a passive eavesdropper, the Random Beamforming Security (RBS) scheme is presented, where the design contains two kernel modules: the random beamformer and the secrecy encoder/decoder. The random beamformer utilizes the difference between the main channel and the wiretap channel to enhance transmitted signal, and construct an artificial random fast fading channel for eavesdropper. As a result, the signals at legitimate receiver are swelled and the signals sent to eavesdropper are deteriorated.
