|Title:||METHOD AND SYSTEM FOR DETECTING WHETHER OBFUSCATION HAS BEEN APPLIED TO DEX FILE AND EVALUATING SECURITY|
A method and a system for detecting whether obfuscation has been applied to a DEX file and evaluating security are provided. The security evaluation method can comprise the steps of: registering an Android application package (APK); searching a DEX file, included in the APK, for an application class; checking whether to call an application programming interface (API) for loading another DEX file further included in the APK, on the basis of a class and a method called by a body instruction of a method included in the application class; and determining that obfuscation has been applied to the DEX file, when the existence of API calling for loading another DEX file is confirmed.
