<p>According to the present invention, in diagnosing a malicious application in a portable terminal such as an Android OS-based smart phone, the malicious application can be rapidly and accurately diagnosed, and performance degradation of the terminal can be prevented by extracting a DEX file including the execution codes of an application in an apk file which is an installation file of the application, uncompressing only a partial region of a DEX file header including hash information for verifying the DEX file in the DEX file, and checking for the presence of the malicious application by comparing the hash information recorded in the DEX file header with signature hash information.</p> |
