The invention discloses a spatio-temporal data file transmission method. The method mainly comprises the steps of obtaining a secret key table of an XXTEA algorithm; dividing the secret key table into four sub secret key tables, performing first mapping on the sub secret key tables and a geocoding table, and performing second mapping on secret key characters in the secret key table and codes in the geocoding table; and according to the first mapping, the second mapping and the calculation of the secret key characters by the XXTEA algorithm, encrypting a plaintext containing geographic information correspondingly, and sending the encrypted plaintext to a receiving end. Through the mapping relation between the secret key character of the XXTEA algorithm and the geocode, the spatio-temporal data file is encrypted according to the calculation of the XXTEA algorithm, and the transmission security of the spatio-temporal data file is improved. The invention further provides a spatio-temporal data file transmission device and system and a storage medium.
Description
technical field [0001] The present application provides a spatiotemporal data file transmission technology, and in particular relates to a spatiotemporal data file transmission method. The present application also relates to a space-time data file transmission device, a storage medium and a space-time data file transmission system. Background technique [0002] At present, encrypted data transmission is only encrypted transmission of the data itself, but with the development of various cracking technologies, only data encryption can no longer meet the needs of secure data transmission. In the prior art, various encryption and decryption data transmission methods are either simple or complex, and the simple encryption method can no longer resist the attacker's cracking, while the complex encryption method will cause the encryption and decryption process to be cumbersome, and finally make the data transmission process difficult. The security cannot be guaranteed, or the cumbe...
