    Key management using visible light communication
    (University of M'sila, 2020-06-10) Djaalab, Amira; Supervisor : Attir, Azedine
    Over many years, researchers have been trying to secure a reliable wireless communication. The main challenge lies in the keys management that cover the creation of a shared secret between two wireless devices through which sensitive information can be exchanged. Several pairing protocols have already been developed in wireless communication, but they do not meet the quest because they use the directly generated secret key as a potentially weak encryption key for authentication, and they are not sufficient to transfer large amounts of data at high speed. So other wireless standards define or define similar protocols, and are designed for specific technologies to solve these shortcomings. In this thesis, a new protocol describing the visible light communication specification is proposed as an alternative solution to existing radio-based protocols in wireless communication which is builded by LEDs to transmit data. This transmission prototype is there tested and analysed with a photodetector in the reception.
