The invention discloses a bidirectional authentication type light-operated entrance guard method. According to the bidirectional authentication type light-operated entrance guard method, a bidirectional authentication type light-operated entrance guard device which comprises a light-operated entrance guard lock and a mobile unlocking terminal is established; the mobile unlocking terminal sends a message to the light-operated entrance guard lock, the legality of the mobile unlocking terminal is authenticated by the light-operated entrance guard lock through messaged authentication, and the light-operated entrance guard lock sends a message to the mobile unlocking terminal after the mobile unlocking terminal is confirmed to be legal; the legality of the message sent by the light-operated entrance guard lock is authenticated by the mobile unlocking terminal, and the mobile unlocking terminal sends an unlocking message C to the light-operated entrance guard lock after the mobile unlocking terminal confirms the legality of the light-operated entrance guard lock; the entrance guard is relieved after the unlocking message is confirmed by the light-operated entrance guard lock. According to the bidirectional authentication type light-operated entrance guard method, the mobile unlocking terminal sends messages by means of light, the light-operated entrance guard lock displays messages by means of LEDs or liquid crystal, the displayed messages are graphic symbols such as bar codes and two-dimension codes, and the mobile unlocking terminal recognizes the displayed messages through scanning with a camera and a scanning head. The bidirectional authentication type light-operated entrance guard method is capable of avoiding information and identity forging of any party and is good in safety performance, privacy protection performance and uniqueness.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical control access control method with two-way authentication. Background technique [0002] Visible Light Communication (VLC for short) technology. VLC technology utilizes the feature that LEDs can emit high-frequency flickering lights that cannot be perceived by the human eye. At the data sending end, the high-frequency flickering of the LED is used to carry the signal, and at the receiving end, the photosensitive element with the same fast response time is used. A method of collecting signals to realize wireless communication. [0003] At present, the wireless access control system mainly adopts radio frequency technology, which has good penetration, so radio frequency signals are easily interfered by electromagnetic waves, intercepted and duplicated, resulting in leakage of unlocking information and property loss. [0004] Visible light is free from ele...
