Security Challenges for Light Emitting Systems

Although visible light communication (VLC) channels are more secure than radio frequency channels, the broadcast nature of VLC links renders them open to eavesdropping. As a result, networks must provide security in order safeguard user’s data from eavesdroppers. In literature, keyless techniques have been developed offer for VLC. Even though these strong against eavesdroppers, they difficult deploy. Key generation algorithms critical securing wireless connections. Nonetheless, many situations, typical key methods may be quite complicated and costly. They consume scarce resources, such as bandwidth. this paper, we propose novel extraction procedure that uses error-correcting coding one time pad (OTP) improve validity data. This system will not any interference problems with other devices. We also explain error correction while sending message across network, suggest change Berlekamp–Massey (BM) algorithm identification assessment. Because each OOK signal frame is encrypted by different key, proposed protocol provides high physical layer security; it allows based on messages sent, so an intruder can never break encryption system, even if latter knows which message; our enables transmission rate bit mismatch rates on-the-fly fetch. The results presented paper were performed using MATLAB.
