Fig. 2 is a flowchart of a data encryption method according to an embodiment of the present application, as shown in fig. 2, the method includes the steps of:
Step S202, determining initial coordinates of a first target celestial body corresponding to target data in a preset coordinate system;
Step S204, determining the running time length of the first target celestial body from the initial coordinates along the running track corresponding to the first target celestial body, wherein the running time length changes along with the change of the current time point;
step S206, determining a target coordinate of the first target celestial body in a preset coordinate system according to the operation time of the first target celestial body and the initial coordinate of the first target celestial body;
Step S208, determining a reference object coordinate of a reference object corresponding to the first target celestial body in a preset coordinate system, and determining a Chebyshev distance between the first target celestial body and the reference object according to the target coordinate and the reference object coordinate;
step S210, determining a key corresponding to the target data according to the Chebyshev distance, and encrypting the target data according to the key.
Before encrypting the target data, classifying all celestial bodies in the universe, such as various stars, planets, comet, meteor, artificial satellites and the like, wherein the stars can store information such as radius, calorific value and the like, the comet and the like can store information such as story-telling discovery time and the like, and the artificial satellites can store information such as birth time, country and the like; the celestial body information of different types is recorded in different dimensions and is stored in a database; the user selects the favorite celestial bodies by himself for encrypting user data, and the user can dynamically switch the favorite celestial bodies at any time.
In the steps S202 to S210, the preset coordinate system may be a cartesian coordinate system, and the running tracks of the specified celestial body at different times are simulated by the cartesian coordinate system, the specified celestial body is the first target celestial body selected by the user, the different celestial bodies select their corresponding coordinate systems of the star, the star reference object in the corresponding coordinate system is used as the origin of coordinates, the corresponding running tracks are dynamically allocated to each celestial body and its coordinate system, the target data is used as parameters, and the initial running coordinate position of the first target celestial body in its corresponding coordinate system is initialized; and obtaining the current time of the system, if the current time is 3 hours, the running time of the first target celestial body is 3 hours, calculating the Chebyshev distance between the coordinate position of the first target celestial body and the coordinate of the reference object corresponding to the first target celestial body after the running time is calculated by calculating the running coordinate position of the first target celestial body after the running time is 3 hours, namely calculating the Chebyshev distance between the coordinate position of the first target celestial body and the coordinate origin under the same coordinate system, and dynamically generating a verification signature, namely a key corresponding to target data by encrypting the target data by calling celestial body information corresponding to the first target celestial body stored in a database, splicing text values corresponding to a plurality of celestial body information into random text information by using a preset splicing function, converting the random text information into binary system, adding the Chebyshev distance and 16-bit random number to an encryption algorithm.
In step S210 of the data encryption method, a key corresponding to the target data is determined according to chebyshev distance, as shown in a flowchart in fig. 3, and specifically includes the following steps:
Step S302, retrieving celestial body information of a first target celestial body from a database;
step S304, splicing Chebyshev distance and celestial body information according to a preset splicing function to obtain a spliced text;
step S306, determining the key according to the spliced text.
In the steps S302 to S306, after the first target celestial body is determined, since the position information of the first target celestial body changes with the movement of time, the chebyshev distance of the first target celestial body is determined by calculation, the celestial body information of the first target celestial body is retrieved from the database, the celestial body information includes information such as description and attribute of the first target celestial body, the chebyshev distance and the celestial body information are spliced by a splicing function to obtain a spliced text, and the spliced text is converted into binary and is added with 16-bit random numbers to form a key.

In the steps S502 to S504, when determining the operation duration of the first target celestial body, it is necessary to use, as a reference time point, a time point corresponding to the determined initial coordinate of the first target celestial body according to the initial coordinate of the first target celestial body in the preset coordinate system, and in an optional embodiment, by determining the current system time, calculating a difference between the current system time and the reference time, and taking a time period length obtained by calculating the difference as the operation duration of the first target celestial body; in another alternative embodiment, the obtained current system time may be directly used as the operation duration of the first target celestial body, without using the reference time point, if the current system time is 3, the operation duration of the first target celestial body is 3 hours.
It should be noted that, the user encrypts the data when storing the data, and then dynamically changes the encryption parameters according to different times, and only the authorized user can automatically decrypt the data into a plaintext when accessing the data; even if the user data file is obtained through an illegal way, the user data file is pure ciphertext, and the dynamic change cannot be decrypted.

In step S210 of the data encryption method, after determining a key corresponding to the target data according to the chebyshev distance and encrypting the target data according to the key, as shown in the flowchart of fig. 7, the data encryption method further includes the following steps:
Step S702, responding to a second selection instruction of the target object, and determining a second target celestial body from a plurality of to-be-selected celestial bodies;
Step S704, determining initial coordinates of a second target celestial body corresponding to the target data in a preset coordinate system;

Step S712, determining a key corresponding to the target data according to the Chebyshev distance, and encrypting the target data according to the key.
In the above steps S702 to S712, it is intended to illustrate that the user (i.e., the target object) may optionally select the target celestial body from the database according to his own preference, and determine the corresponding encryption key according to the celestial body information corresponding to the target celestial body and the chebyshev distance of the target celestial body, which is consistent with the explanation related to the data encryption method shown in fig. 2 to 6, and will not be repeated here.
