The increasing functional complexity and diversity of the weapon systems has reinforced the significance of weapon system software. However, as the range of software functions expands, the insertion of core algorithms and critical data into the weapon system execution binaries, and reverse engineering has facilitated hacking and tampering of such information with malicious intent. In this paper, we propose an obfuscation tool that utilizes obfuscation techniques against source code for the development of weapon system software. In particular, control flow obfuscation techniques were applied to obfuscate core algorithms, and data obfuscation techniques were proposed to conceal important data. In addition, considering the actual performance of the weapon system software, the system was implemented in a user-friendly and flexible structure for selection based on level. The experimental findings confirmed the performance of the techniques used. These source code-based obfuscation techniques can be used to create anti-reverse engineering binary files and to develop anti-tampering platforms for weapon system software in the future.
