演講題目：A MAC-Layer Stream Cypher Mechanism for Visible Light Communication
演講摘要：The LED light bulbs not only can provide bright but also can be
employed for data communication and object positioning,
namely visible light communication (VLC)). VLC is
fast-growing technologies that enable new visible light
application such as fast data transmission and indoor positioning.
Due to its attractive functionalities, they have draw lots of
attention to the wireless communication and indoor navigation
systems. Because of its physical characteristics, “what you see
is what you send”, VLC has been always considered as a secured
communication method. However, in this work, we analyze the
risks of visible light communication signal such as signal
jamming, data snooping and modification. In order to effectively
protect VLC data communication problems, we design a
mac-layer stream cypher data communication through the VLC
signal to achieve the secure of the data communication.
