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