| description | The invention relates to the technical field of IT network communication, and particularly discloses a clock-based nonlinear encryption method and device. Comprising the steps that S1, a random number generator generates a random constant and obtains current time through a Beidou clock; the access end obtains a dynamic secret key through nonlinear calculation according to the random constant and the current time; the access end sends the dynamic secret key to a server; after receiving the dynamic secret key, the server obtains an expected dynamic secret key through nonlinear calculation, and the server performs verification according to the dynamic secret key and the expected dynamic secret key to obtain a verification result; and the server confirms whether the visitor is legal based on the verification result. A clock-based nonlinear secret key algorithm is provided, clock synchronization is carried out through a Beidou time service system, more strict identity recognition can be carried out on a visitor, s |
