What is it about?
In this work, we designed a physical-layer key generation protocol that can overcome known/chosen plaintext attacks in visible light communication. We exploite the random feature of input data and chaotic sequences generated from chaotic scheme to create dynamic cyphertexts by chaotic permutation of OFDM subcarriers in time/frequency domains and chaotic polarity reversal of time-domain OFDM samples. The results showed that the protocol has a high robustness against known/chosen plaintext and brute-force attacks

Why is it important?
The prposed protocol can protect the user information against malicious attacks in some senstive areas like banks where the security is urgent.
Perspectives
The physical-layer security in visible light communication is a very area of research. Our propsed protocol can contribute in the advance in this field.
