Abstract

The invention provides an anti-rollback method and a system, which relate to the field of software security. The anti-rollback method provides a storage unit for storing a version form of a first version number of an application program. The anti-rollback method comprises the following steps: acquiring a second version number of the application program; comparing the second version number with a minimum first version number in a version form associated with the application in the storage unit, and inhibiting loading of the application when the second version number is smaller than the minimumfirst version number. The version form of the application program is stored through the storage unit, so the security of the application program to be loaded according to the version form is ensured when the application program is loaded, and the purpose that the application program loading can be prohibited under the condition of finding a vulnerability or a security hidden danger is realized.

Description

technical field [0001] The invention relates to the field of software security, in particular to an application program anti-rollback method and system. Background technique [0002] Network security issues are getting more and more public attention. With the development of network technology and the popularization of intelligent systems such as home multimedia systems and mobile phones, online shopping through home multimedia systems or computer mobile phones, payment of household water and electricity bills, purchase and playback of digital audio-visual works and other new consumption and shopping methods have gradually entered the family. Life. Therefore, more and more attention has been paid to the security of mobile terminals. At present, in mainstream home multimedia systems and mobile terminal systems such as mobile phones and tablets, TrustZone technology of ARM (full name: Advanced RISC Machines) processors is generally used to build a trusted execution environment...
