摘要： A handshake synchronization restoration method and system based on visible light communication are provided. The method includes: after a transmitting end in which a state machine varies with unit time is powered on again, transmitting in the form of a visible light signal, to a receive and control system, a status reset signal which varies with unit time, wherein the receive and control system comprises one or multiple receiving ends; and receiving, by the receive and control system, the visible light signal, and when it is determined that the received visible light signal is a status reset signal, adjusting status of a state machine of a receiving end to a state indicated by the status reset signal. Status synchronization with the transmitting end is restored, avoiding a case in which the transmitting end is asynchronous with the receiving end after encountering power outage and being powered on again.

摘要： Embodiments of the present invention provide a method and system of encryption, decryption, and encryption and decryption based on visible light communication. A transmit end performs a logical operation on an original data signal and a pseudocode signal varying with a unit interval to obtain a scrambling code signal, and sends the scrambling code signal in a form of a visible light signal. A receive end receives the visible light signal sent by the transmit end, and converts the visible light signal into a digital signal; and decodes the digital signal and a pseudocode signal varying with a unit interval, so as to obtain the original data signal. The visible light signal transmitted between the transmit end and the receive end is not original data, but a scrambling code signal varying with a unit interval, thereby improving security of the photonic Internet of Things.
