Abstract

Control obfuscation can greatly increase the difficulty on detecting implementation path of Android application, and also is the one of the main difficulties on current code static analysis. This article researched this question and designed a system DOCFDroid used to solve this problem. The system obtained the CFG relation matrix in the pretreatment stage, and used the depth-first algorithm to find the set of the path. According to the set of source points and the set of end points, it obtained the coarse path. The algorithm of weight screening could effectively obtain the target path set. Based on the sample set DroidBench 1.2, it further constructed the test sample set to verify the validity of this method. The experimental results show that the system can effectively resist the interference caused by control obfuscation, and the recognition rate of target path can reach 95.31%.
