Target partition verification method and device, storage medium and computer equipment

Abstract

The invention discloses a target partition verification method and device, a storage medium and computer equipment, and the method comprises the steps: obtaining a list file of a target partition andstandard verification data corresponding to the list file, and enabling the list file to record the verification values of a part of files stored in the target partition; performing verification calculation on the list file to obtain current verification data, and comparing the current verification data with the standard verification data; if the current verification data is consistent with the standard verification data, performing verification calculation on the partial files to obtain a current verification value of each file; and when the current check value of each file is consistent withthe check value of the corresponding file recorded in the list file, determining that the target partition passes the check. Through adoption of the method, the performance of the equipment is not influenced while the partition integrity of the system can be ensured.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method and device for verifying a target partition, a storage medium, and computer equipment. Background technique [0002] Among the currently used smart devices, the Android (Android) system is widely used. On an Android device, if the system partition is tampered with by a malicious program (such as being rooted), it will bring danger to the user, and the system partition needs to be protected. The Android platform's existing integrity check function (dm-verity) for blocks in the device, for example, during the booting phase of the device, due to the need to verify all blocks of the target device, will cause device performance to degrade (in The action of checking will be added when reading block operations), especially on devices with low RAM, the performance degradation is particularly obvious, and a good balance between "security" and "performance" cannot be reached.
