Photonic authentication system for a receiver terminal and transmitter terminal

A method for right authentication in an authentication system, wherein the authentication system comprises a transmit terminal and a receive terminal, and the transmit terminal comprises a transmitter, the receive terminal comprises a receiver and a controller that are connected, and the method comprises:

• externally propagating, by the receiver, an acquired identification code information set corresponding to the receiver;
• after receiving the identification code information set transmitted by the receiver, performing a first right authentication on whether the transmitter has operation rights by the transmitter according to the received identification code information set, and determining whether to allow converting transmitter information of the transmitter into a light signal for transmission according to an authentication result, where the transmitter information comprises at least a unique identification code of the transmitter;
• wherein the first right authentication includes the following steps:
• comparing the unique identification code of the transmitter with the received identification code information set, and if the received identification code information set comprises the unique identification code of the transmitter, controlling a light transmit device to switch to a enable state that allows converting transmitter information of the transmitter into the light signal for transmission;
• after the receive terminal receives, by using a light receive device, the transmitter information that is transmitted by the transmitter in a light signal form, performing a second right authentication on the transmitter information by the controller;
• wherein the second right authentication includes the following steps:
• comparing a transmitter information with the identification code information set, and if the identification code information set includes the transmitter information, outputting a first control signal to a controllable lock to control unlocking of the controllable lock;
• wherein the identification code information set comprises the unique identification code information of all transmitters corresponding to the receiver, wherein the all transmitters have rights to open a door controlled by the receiver;
• wherein the transmitter further includes a power supply, a trigger switch, a control switch and a processor, where the trigger switch and the control switch are wired in series between the power supply and the light transmit device;
• a control end of the control switch is coupled to the processor, and the control switch switches between an on state and an off state according to a control signal output by the processor;
• the trigger switch is configured to switch between an on state and an off state in response to an operation of a user;
• and
• wherein the receiver performs encrypting the identification code information set, and when the transmitter receives the encrypted identification code information set transmitted by the receiver, the transmitter performs decrypting the identification code information set.
