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