Abstract
- The last decade has witnessed an increase in adopting wireless systems. A wireless system enables two devices to utilize radio frequencies to communicate wirelessly. Moreover, in wireless systems, authentication can be performed wirelessly through transferring authentication information over-the-air. Alternatively, antennas in most devices enabled to communicate wirelessly today can control the power level of transmission to improve the wireless system’s performance. In the present study, we examine the feasibility of varying the power level of transmission of a device’s antenna for authentication purposes. This can be used in applications, such as obstructing relay attacks on wireless authentication systems. Furthermore, a prototype is built and tested utilizing Wi-Fi enabled systems.
