Embodiment Construction

[0017] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The invention adopts the encryption algorithm and combines the communication ability of the mobile phone to propose a new method for preventing the application program of the mobile terminal from being illegally upgraded.

[0019] The RSA encryption algorithm is a public key infrastructure (PKI for short) technology, which is an asymmetric algorithm based on a public key, which uses two very large prime numbers to generate completely different public keys (ie , the encryption key) and the private key (ie, the decryption key). Using the RSA algorithm for encryption and identity verification has a high ability to resist attacks. Introducing this algorithm into the mobile phone for security design can greatly improve the security performance of the mobile phone.

Abstract

The disclosed method for preventing illegal upgrading the mobile terminal application program comprises: S102, the mobile terminal and the upgrade device take interaction for upgrading; S1104, the terminal identifies the upgrade device, if the device passes the identification, goes to next step, or lese finishes the process; and S106, the mobile terminal validates the upgrade version program, if the version passes the validating, the terminal downloads the program for upgrading, or else finishes the process. This invention is efficient.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for preventing illegal upgrading of application programs of mobile terminals. Background technique [0002] Mobile phone software can be downloaded to the mobile phone with various download software, such as Qualcomm's Qualcomm Product Support Tool (QUALCOMM Product Support Tool, referred to as QPST), which can download the software of its corresponding platform to the mobile phone, which is the most convenient way for maintenance points. A simple version upgrade method commonly used. [0003] One of the most commonly used methods for mobile phone software upgrades is to download the corresponding download agent software into the mobile phone after the download software interacts with the mobile phone and start to enter a download mode. After the mobile phone enters the download mode, it runs under the control of the download agent software. The downloa...
