Wireless LANs, or WiFi, have enabled many new applications due to their wireless nature. One such application is location service which allows devices to determine its location using information from WiFi infrastructure. However, wireless communication is susceptible to eavesdropping and jamming. Once the wireless signal is jammed, an attacker can set up fake access points to impersonate a legitimate...
The wireless networks lack a physical boundary due to the broadcasting nature of wireless transmissions. The security has become a critical concern in the physical layer of the wireless networks. In this paper, we propose a novel MIMO-aided security scheme. By exploiting an extra dimension provided by MIMO systems for adding artificial noise to the transmission process, which let the attacker's signal...
