System and method for integrity verification of banking application using APK file dynamic loading technique

摘要

The present invention provides a system and a method for verifying integrity of a banking application using an android application package (APK) file dynamic loading technique, which frequently change a DEX file which is a dynamic loading module transmitted from a server, apply a technique dynamically changing an APK path in a dalvik virtual machine when a native library requests an original APK path, and verify integrity of a banking application. More specifically, the system for verifying integrity of a banking application using an APK file dynamic loading technique comprises: a server converting and storing a java class into the DEX file, and transmitting the DEX file to the banking application by a request of the banking application; and the banking application calculating a first hash value based on the DEX file, and generating a second hash value for verifying the integrity by dynamically receiving the APK file path. The server verifies the integrity based on the first hash value and the second hash value.
