A reverse engineering approach of obfuscated array

Recently, research community has advanced in type reconstruction technology for reverse engineering. However, emerging with obfuscated technology, data type reconstruction grows more and more difficult, and obfuscated code is easier to be monitored and analyzed by attacker or hacker. Therefore, it's essential to develop a novel approach to reverse engineering obfuscated array type based on refined CFG. We take split array for example and analyze feature in CFG and take advantage of compiler algorithm to identify obfuscated array.
