Embodiment Construction

[0028] Such as figure 1 As shown, a system built-in software upgrade method includes the following steps:

[0029] Step S110, performing signature verification on the upgrade package, and judging whether the signature verification can be passed. The upgrade package may be a data package pre-stored locally, or may be downloaded through a network (such as a 3G mobile communication network). Since it is to upgrade the built-in software of the system, the identification of the software itself is very important. Only the upgrade package that has passed the signature authentication can be regarded as a trusted upgrade package, so as to avoid being used by malicious software to affect the stability and security of the system. The digital signature used in signature authentication adopts the public key encryption system. The public key encryption system allows anyone to use the private key to encrypt when sending information. The digital signature allows the information receiver to u...

Abstract

The invention provides an upgrading method of system built-in software, which comprises the following steps: carrying out signature authentication on an upgrade pack and judging whether the upgrade pack can pass signature authentication; acquiring the upgrade rights of the built-in software; and if the upgrade pack passes signature authentication, using the upgrade pack for upgrading according to the upgrade rights of the built-in software. By signature and rights management, the upgrading method provided by the invention realizes upgrading of the system built-in software, solves the problem of possible safety hazard caused by built-in software upgrading, and facilitates the user to update the system built-in software immediately. In addition, the invention also provides a mobile terminal.

Description

【Technical field】 [0001] The invention relates to software upgrading technology, in particular to a system built-in software upgrading method and a mobile terminal. 【Background technique】 [0002] Usually, for security reasons, the built-in application software in the system is not allowed to be uninstalled and upgraded by the user, and the built-in software can only be upgraded when the entire system is upgraded, which brings inconvenience to the user; at the same time, the manufacturer It is also impossible to release a newer version of the system built-in software installation package in time to provide users with upgrades. [0003] For example, when a terminal manufacturer releases a certain ANDROID (the name of an open-source mobile phone operating system based on the Linux platform), it has a built-in input method version V1.0, and subsequent ANDROID products have built-in input method version V2. The product does not provide a system upgrade solution for input method...
