La sécurité dans les communications en lumière visible (VLC) a pris une importance croissante ces dernières années. Le multiplexage par répartition orthogonale de la fréquence optique asymétrique (ACO-OFDM) est reconnu comme l'une des techniques OFDM les plus puissantes et les plus efficaces. Par conséquent, il est bien adapté à une utilisation dans les connexions de liaison montante et descendante. Un protocole de sécurité basé sur cette technique peut faciliter des connexions sécurisées en liaison montante et descendante. Dans la présente étude, une méthode de chiffrement de génération de clé de couche physique de faible complexité est conçue à l'aide de la technique ACO-OFDM pour les réseaux VLC intérieurs. La méthode de sécurité dépend de la génération de clés secrètes à partir des échantillons OFDM de préfixe cyclique positionnés dans la zone à faible impact du canal pour chiffrer toutes les trames de signal avant la transmission, tout au long de la session. Les résultats numériques indiquent que le mécanisme de génération de clé devrait être mis en œuvre pendant la transmission de données en liaison descendante tout au long d'une période de session afin de fournir des clés pour les connexions en liaison descendante et en liaison montante. Dans cette configuration, le combiné de l'utilisateur utilise les clés secrètes générées lors de la transmission de données en liaison descendante pour chiffrer sa transmission en liaison montante. Cette configuration préserve la durée de vie de la batterie du combiné. De plus, les résultats indiquent que la méthode de sécurité proposée peut atteindre un taux de non-concordance de clé nul avec la création de clé à la volée.

Abstract: Security in visible-light communication (VLC) has seen increasing importance in recent years. Asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) is recognized as one of the most powerful and efficient OFDM techniques. Therefore, it is well suited for use in both uplink and downlink connections. A security protocol based on this technique can facilitate secure uplink and downlink connections. In the present study, a low-complexity physical-layer key-generation encryption method is designed using the ACO-OFDM technique 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. Numerical results indicate that the key-generation mechanism should be implemented during downlink data transmission throughout a session period to provide keys for both downlink and uplink connections. In this setup, the handset of the user employs the secret keys generated during downlink data transmission to encrypt its uplink transmission. This setup conserves the battery life of the handset. Additionally, the results indicate that the proposed security method can achieve a zero key mismatch rate with on-the-fly key creation.
