Code obfuscation apparatus and method using identifier conversion that is difficult to distinguish

摘要

The present invention relates to a code obfuscation apparatus and method using identifier conversion, and a code obfuscation apparatus according to an embodiment of the present invention extracts an application program file and extracts a Darvik execution file. A code analysis unit that analyzes the byte code of the extracted Darvik executable file, a control unit that selects the type, number, and insertion position of the obfuscated characters, and inserts the selected obfuscated characters into the byte code. And an identifier conversion unit for converting the identifiers. As described above, according to the present invention, the reverse engineering resistance of the static analysis base is improved by converting the identifier using an obfuscated character that is not represented on the screen or is represented by the same character as the other characters. Can be increased. [Selection] Figure 4
