Sensitive information timestamp encryption transmission method

The invention provides a sensitive information timestamp encryption transmission method, and relates to the technical field of information transmission, and the method comprises the steps: S1, obtaining the total duration T of information transmission; s2, an optical signal time domain unit of the wide-spectrum laser source is set to be amplified to time T; s3, when each transmission signal is generated, obtaining a dispersion pattern when the wide-spectrum laser source is introduced into the fiber bragg grating, and adding the dispersion pattern into the generated transmission signal as a timestamp pattern; and S4, randomly disorganizing the sequence of the multiple groups of transmission signals, and sending by taking time T as a period. The method is simple and convenient, a large group of data is divided into a plurality of data slots, and after each data slot is endowed with a timestamp through the first optical pattern without the second optical pattern, the plurality of groups of data slots are disorde
