摘要
A method for protecting an APK file by obfuscating and encrypting a DEX file and a negative library, which is performed by an APK file protection system, comprises the steps of: (a) applying a DEX file analysis tool prevention method for adding a command for disturbing decompiling to each method of the DEX file; (b) inserting a code for acquiring a decryption key for decrypting the negative library into the APK file; (c) encrypting the negative library and storing the encrypted negative library in a folder with read authority in the APK file; (d) decrypting the encrypted negative library in the APK file, storing the decrypted negative library in a folder with write authority for an application, and changing the path of the negative library in a call syntax of the negative library in the DEX file, to normally operate the application during the execution of the application; and (e) encrypting the DEX file, storing the DEX file in the folder with read authority in the APK file, deleting the DEX file which is not encrypted, generating a temporary DEX file, and inserting a code for decrypting the encrypted DEX file in the temporary DEX file.;COPYRIGHT KIPO 2016
