Provided are a handshake synchronization method and system based on visible light communication. The method comprises: a transmitting end, a state machine of which changes over unit time, being connected to a receiving end, the state of a state machine of the receiving end being synchronized with the state of the state machine of the transmitting end; the transmitting end scrambling an original signal and a light guide signal using a pseudocode signal which changes over unit time, and sending out the scrambled signal after the scrambling in the form of a visible light signal; and the receiving end receiving the visible light signal, identifying the scrambled signal of the current period of time by means of the light guide signal, and decrypting the original signal according to the scrambled signal. Since a visible light signal which is transmitted between a transmitting end and a receiving end is not an original signal, the security of a photon Internet of Things is improved. |
