Secure data Communication using Chaos Synch Sequence on VLC Systems

Radio communication (RF) is the older communication technology which has many standards to form an updated version of 5G and above. It is a cost effective system for experimenting and implementing because of its available equipment. Under higher order and higher spectrum level it may harm human beings because it can penetrate through walls. This effect can be overcome by the growing technology like light communication. It has more benefits than conventional RF systems. Here, a high security module reduces data loss for the new technology system and also derive analytical expression. In the proposed model chaotic sequence is generated using Rossler algorithm. These sequences would look like a noise to cover the message signal. To improve the encryption strength it uses Lorenz and tent algorithm as a multi-threaded algorithm (MTA). This chaotic system is a dynamic spreading of sequence that are more sensitive and so authenticated users can retrieve the information during the transmission. The data security is given in such a way that even malicious attacker cannot retrieve the data when they do the snooping. Through the simulation using multi-threaded algorithm, the results have proved that it is a validated security algorithm. The obtained values from the analysis would provide high security information transmission for the VLC model with the better BER of 10-6 to 10-4.
