Abstract :
This paper investigates the impact of data encryption and decryption in indoor broadcasting visible light communications (VLC) system embedded in the physical layer. The RSA encryption has been implemented to provide a secure data transmission in the physical layer. The paper shows that the bit error rate (BER) performance for the un-secured and secured VLC systems (8 and 12-bit) for data rates of 2 and 12 Mbps. For a BER of 10-4 we show that there is 2-4 dB power penalties with the secured VLCs. Investigation of key length impact on the error propagation as well as power penalty is also carried out.
