摘要： The present invention discloses a visible light encryption method, a decryption method, a communication device and a communication system. The method includes: receiving a visible light signal from a transmit end, where the visible light signal is encrypted at the transmit end by using a key; and obtaining the key, and decrypting the visible light signal according to the key, where the obtaining the key includes: obtaining a key corresponding to a state of a state machine of a receive end; or, obtaining indication information according to the visible light signal and obtaining the key according to the indication information, where the indication information is used to obtain the key. The present invention solves a problem of decryption failure in visible light encryption and decryption, and improves accuracy of decryption.
