Wireless networks strive to integrate information technology into every corner of the world. This openness of radio propagation is one reason why holistic wireless security mechanisms only rarely enter the picture. In this paper. we propose a physical (PHY)-layer security authentication scheme that takes advantage of channel randomness to detect spoofing attacks in wireless networks. https://www.spidertattooz.com/The-GelBottle-Inc-BIAB-Gel-Polish-Spirited-67oz-p17706/
