Abstract

The invention discloses a method and system for classifying and encrypting Android APK files, belonging to the technical field of mobile phone applications. The invention obtains the fixed value in the constant counter of the Android application program APK to be classified and the fixed value of the number of program usage methods; The fixed value and the fixed value of the number of program usage methods are compared with the training set data in the KNN classification algorithm that has completed the training to determine the type of the Android application APK to be classified; determine the corresponding known encryption method according to the type, and then determine the corresponding known encryption method for the Android application. APK is encrypted; use different encryption technologies for different types of APPs to ensure that the entire company's products will not be cracked if one APK is cracked; if you want to crack all products, you need to crack every algorithm, which increases the cost and security; at the same time, different values ​​of K in the KNN classification method are used to further realize dynamic encryption within a certain range.

Description

technical field [0001] The invention relates to the technical field of mobile phone applications, in particular to a method and system for classifying and encrypting Android APK files. Background technique [0002] Apps currently running on the Android system are generally less secure. The android virtual machine operating system is born out of the operating principle of the java virtual machine, and can be decompiled at any time; even if it is confused, it may still be cracked if careful research and analysis are carried out; the APP encryption technology visible on the market is based on a set of Encryption method, that is to say, each APP uses the same encryption scheme; this encryption scheme is nothing more than continuing to conduct in-depth research on encryption algorithms, but once a decryption method is found. All apps will be cracked. In certain environments and situations, there will be certain risks. Contents of the invention [0003] The invention provides...
