Design and Development of Secured Data Transfer System in Li-Fi

The internet users are exponentially increasing day by day with a heavy load on spectrum. Li-Fi – a new trending technology opened the doors for communication with high speed. It is a visible light communication to transmit or receive data. The protection of data from unauthorized users is highly needed in this communication in its vicinity. Existing algorithms provides security but it involves lot of processing time which is higher than the communication time. Therefore, light weight algorithms are very much in demand. In this paper, a new light weight security mechanism is presented to avoid the access from others. The proposed mechanism provides better security in Li-Fi communication with high speed for future networks.
