Step S303, associating public and private key pairs;
and associating the public key and the private key to form a key pair through the distance between the celestial body and the sun in revolution, the revolution and rotation period difference value and the calculated prefix.
Step S304, the public key is issued to the client side to encrypt data through the public key;
the public key is issued to the client, the client encrypts data through the public key, and the server decrypts the data through the private key; otherwise, the server side encrypts the data through the private key, and the client side decrypts the data through the public key.
In step S305, the server decrypts the data through the private key.
According to the revolution and rotation calculation result, the complexity of key generation is influenced, and further the encryption efficiency is influenced, and enterprises can utilize the characteristic that the closer the celestial body revolution and rotation is to the sun, the larger the instant linear velocity and the instant angular velocity are, according to the requirement of security level.

8. The method of claim 7, further comprising: and acquiring the distance information between the target star and the revolution center, and establishing the association between the public key and the private key according to the difference between the revolution period and the self-transmission period of the target star.
9. A method of data transmission, comprising:
receiving encrypted data, wherein the encrypted data is obtained by encrypting data to be transmitted according to a key determined by revolution information of a target star;
acquiring self-transmission information corresponding to the target star, and determining a private key according to the self-transmission information;
and decrypting the encrypted data by adopting the private key to obtain the data to be transmitted.
10. The method of claim 9, wherein the determination of the target star comprises:
determining the security level of the data to be transmitted;
determining a candidate celestial body set corresponding to the security level from a celestial body information set;
sorting celestial bodies in the candidate celestial body set from high to low in priority, wherein the closer the celestial bodies in the celestial body information set are to the revolution center, the higher the priority of the celestial bodies is;
and selecting the target celestial body from the candidate celestial body set according to the sorting result.
11. A data transmission apparatus, comprising:
the acquisition module is used for acquiring data to be transmitted;
the selection module is used for selecting a target star from the celestial body information set corresponding to the target galaxy;
the determining module is used for determining revolution information corresponding to the target star and determining a public key according to the revolution information;
