Method for a terminal to acquire and access data

A method for a terminal to access data, the method comprising:

• the terminal detecting whether there is a configuration file related to the data to be accessed;
• In case of detecting the configuration file, the terminal generating a decryption key based on its identification information to decrypt the configuration file;
• extracting verification information from the decrypted configuration file;
• comparing the verification information with a verification code, and if they are consistent, the terminal accessing the data, wherein the verification code is generated by encrypting the identification information of the terminal.

A method for a server to process an acquisition request from a terminal, comprising:

• The server receiving an acquisition request for acquiring data from the terminal, wherein the acquisition request comprises identification information for identifying the terminal;
• processing the acquisition request, and judging whether the terminal is a serviceable terminal according to the identification information;
• sending a request for the terminal to provide a first information when the judgment result is that the terminal is a serviceable terminal;
• generating an encryption key for a configuration file based on at least the first information when the first information from the terminal is received;
• the server using a digest algorithm to process the identification information, and writing the processing result into a configuration file;
• encrypting the configuration file with the encryption key;
• and
• sending the encrypted configuration file and the data to the terminal.
