An Approach for Secure Communication using LiFi Technology with Laser in Border Areas

In border areas where the risk of unauthorized interception is high, the proposed LiFi system presents a valuable solution. Unlike conventional systems that broadcast signals in the receiver’s direction, making them susceptible to interception, our system utilizes optical laser technology for data transfer. The unique feature of this system is that only aligned receivers can effectively receive the data, significantly reducing the risk of unauthorized interception. Moreover, data transmission is limited to line-of-sight scenarios, minimizing the possibility of interception. In the rare event of an unauthorized receiver gaining access, the authorized receiver can promptly detect the interception by observing the absence of data reception through the laser. This ability provides a safeguard against potential threats, enabling the option to halt communication or counteract any attempt at transmitting misleading information. This research contributes to the advancement of secure communication strategies, particularly in sensitive border region.
