Reverse engineering algorithms
Decompiling is an area of interest for researchers in the field of software reverse engineering. When the source code from a high-level programming language is compiled, it loses a great deal of information, including code structure, syntax, and punctuation.
The purpose of this research is to develop an algorithm that can efficiently decompile assembly language into pseudo C code. There are tools available that claim to extract high-level code from an executable file, but the results of these tools tend to be inaccurate and unreadable.
Our proposed algorithm can decompile assembly code to recover many basic high-level programming structures, including if/else, loops, switches, and math instructions. The approach adopted here is different from that of existing tools. Our algorithm performs three passes through the assembly code, and includes a virtual execution of each assembly instruction. We also construct a dependency graph and incidence list to aid in the decompilation.
