Abstract
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.
