Embodiment Construction
[0028] The main idea of the present invention is to store the public key in the mobile terminal, store the private key separately in the download tool unit and the data to be downloaded in the computer, and encrypt and decrypt the identification information of the mobile terminal, so that the mobile terminal, download The tool unit has a one-to-one correspondence with the data to be downloaded in the computer, so as to prevent the network lock card lock function of the mobile phone from being cracked by using the download channel.
[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] According to an embodiment of the present invention, a method for downloading application data of a mobile terminal is proposed.
[0031] figure 1 It is a flowchart of a method for downloading applic...

The invention discloses a mobile terminal application data downloading method, system and a mobile terminal. The method comprises the following steps: the mobile terminal sends identification information to a computer; the mobile terminal receives a mobile terminal identification information ciphertext from the computer, and the mobile terminal identification information ciphertext is enciphered by a private key formed from a first sub private key and a second sub private key, wherein the data to be downloaded in the computer carries the first sub private key, and a downloading tool unit in the computer carries the second sub private key; the mobile terminal uses a public key deciphering mobile terminal identification information ciphertext stored in advance to obtain a mobile terminal identification information plaintext and compares the mobile terminal identification information plaintext obtained by deciphering with the identification information of the mobile terminal per se; and if the comparison results are the same, the mobile terminal sends a downloading request message to the downloading tool unit to download the data to be downloaded. The invention can prevent a downloading channel from being used for cracking the net locking and card locking functions of the mobile terminal.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and system for downloading application data of a mobile terminal and a mobile terminal. Background technique [0002] With the maturity and development of electronic technology, mobile terminals such as mobile phones are becoming more and more popular. In order to better develop customers, mobile operators sometimes sell mobile phones to customers at a price lower than the cost, or even give them to customers for free. At the same time, mobile operators require that such mobile phones must be locked to the network of the mobile operator, or to lock the Subscriber Identity Model (SIM card for short) of the mobile operator, which is the so-called network lock card. [0003] But thereupon, the code or data of using the download path of the mobile phone to illegally rewrite the mobile phone memory is produced, the mobile phone is cracked, and the function of locking the network or...
