Design of Physical Layer Key Generation Encryption Method Using ACO-OFDM in VLC networks

What is it about?

Security in visible-light communication (VLC) has seen increasing importance in recent years. In this work, we designed a low-complexity physical-layer key-generation encryption method for indoor VLC networks. The security method is contingent on the generation of secret keys from the cyclic prefix OFDM samples positioned in the low-channel impact area to encrypt all signal frames before transmission, throughout the session.

From the results, the proposed security method can achieve a zero key mismatch rate with on-the-fly key creation.
