Symbolic execution based control flow graph extraction method for Android native codes

Blog Article

A symbolic execution based method was proposed to automatically extract control flow graphs from native libraries of Android applications.The proposed method can provide execution environments for functions propper wildland shirt in native libraries,simulate JNI function call processes and solve symbols using constraint solver.A control flow graph extraction prototype system named CFGNative was photos de carhartt wip store toulouse implemented.The experiment results show that CFGNative can accurately distinguish all the JNI function calls and native methods of the representative example,and reach high code coverage within acceptable time.
