Android system security verification method and verification device thereof

Abstract

The invention provides an Android system security verification method used on a terminal and a verification device thereof. According to the Android system security verification method, an original system file Hash list is stored in the terminal; the Android system security verification method comprises file Hash verification; particularly, file Hash verification comprises the following steps: reading a system film of an Android system, checking whether the system film is stored under a system directory of the Android system, finding out a corresponding original Hash value in the Hash value list according to the system file, calculating the current Hash value of the system file, judging whether the original Hash value is equal to the current Hash value, and if the original Hash value is equal to the current Hash value, feeding back the system file, thereby successfully completing the security verification. As the original Hash value is written into the terminal and is used as verification data, the Android system is verified in an offline verification mode, the verification on system security is achieved with the smallest power consumption, the smoothness and the security of the system are also improved, and the inconvenience in upgrading verification is avoided.

Description

technical field [0001] The invention relates to the technical security field, in particular to an Android system security verification method and a verification device thereof. Background technique [0002] With the emergence of more and more viruses and illegal programs on the Android system, the security of Android devices is seriously threatened. Therefore, Android devices have an increasing need for security performance, and Android systems are required to perform security verification when starting, that is, to verify whether their system files have been maliciously tampered with. The current verification method for starting the Android system cannot solve the contradiction between security performance and fluency of use. Some solutions can guarantee security verification, but affect the smoothness of Android use or other functions. Although some solutions do not affect the fluency of using the Android system, the security performance is easily affected. [0003] At ...

Problems solved by technology

The main reason is that the security verification scheme provided in Google’s native code is an offline verification method in units of binary data, which can ensure the security of the system. However, the disadvantage of this verification method is that the size of the upgrade differential package will expand rapidly, which seriously wastes the upgrade download traffic.
