APPARATUS AND METHOD FOR CODE OBFUSCATION USING INDISTINGUISHABLE IDENTIFIER CONVERSION

摘要

The present invention relates to an apparatus and a method for code obfuscation using identifier conversion. An apparatus for code obfuscation according to an exemplary embodiment of the present invention includes: an extractor that extracts a dalvik executable file by decompressing compression of an application program file; a code analyzer that analyzes a bytecode of the extracted dalvik executable file; a controller that selects a kind, the number, and an insertion position of obfuscation characters; and an identifier converter that converts an identifier of the bytecode by inserting the selected obfuscation characters into the bytecodes. According to the present invention, it is possible to increase the static the obfuscation characters which are not displayed on the screen or which are expressed by the same characters as other characters.
