Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments in no way limit the present invention.

[0038] like Figure 1-2 As shown, the hybrid feature screening method for Android malware detection includes the following steps:

[0039] 1) Generate a training set and a test set based on existing data; use the decompilation tool Apktool to decompile the collected APK files to obtain the manifest file AndroidManifest.xml during Android software installation; use the xml.etree.ElementTree module in Python to analyze The manifest file AndroidManifest.xml, counts the permissions, intents and component information in the manifest file AndroidManifest.xml; quantifies the presence or absence of permissions and intents as 0 and 1, and lists the windows, services, broadcast receivers and content in the manifest file AndroidManifest.xml The number of providers is used as the quantif...

Abstract

The invention discloses a hybrid feature screening method for Android malicious software detection. The method comprises the steps that a training set and a test set are generated according to existing data; a primary feature subset is screened out; an optimal feature subset corresponding to each type of classifiers is obtained; and the optimal feature subset is utilized to train the correspondingclassifiers. Through the hybrid feature screening method for Android malicious software detection, the optimal feature subset and a classification algorithm matched with the optimal feature subset can be screened out, modeling time of the classifiers is greatly shortened, and the detection efficiency and detection precision of Android malicious software detection can be improved.

Description

technical field [0001] The invention relates to the technical field of software security, in particular to a mixed feature screening method for Android malware detection. Background technique [0002] According to the latest statistics from the market research company Strategy Analytics, in the third quarter of 2016, the global market share of Android reached a record 87.5%, while the global market share of iOS fell to 12.1%, mainly due to the openness of the Android system. However, the openness also leads to the proliferation of Android malware, and these malware (such as spyware, scareware, and adware, etc.) have brought serious security threats to users. The increasingly severe security situation of Android mobile phones makes how to detect Android malware quickly and efficiently become a current research hotspot. [0003] Because machine learning has the ability to process data on a large scale and can make judgments on targets in similar data structures, many research...
