Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] As shown in Figure 1.
[0024] A tax monitoring method for output of mineral resources, first installing mineral data tax monitoring equipment at each mining point;
[0025] Secondly, the GPRS communication method is used to transmit data, and long or short connections can be used to meet different needs.
[0026] Third, adopt CRC (Cyclic Redundancy Check) to ensure data integrity.
[0027] Fourth, the mining data is encrypted and decrypted using an encryption algorithm. The encryption first performs an MD5 digest on the generated mineral data, and the generated 20-byte data is appended to the plaintext data as a data signature, and then the root key and coal mine data tax monitoring equipment The machine number generates an encryption key, and the data generated above is encrypted using the AES encryption algorithm to obtain ciphertext to ensu...
