RouAlign - Cross-Version Function Alignment and Routine Recovery with Graphlet Edge Embedding.

Reverse engineering is labor-intensive work to understand the inner implementation of a program, and is necessary for malware analysis, vulnerability hunting, etc. Cross-version function identification and subroutine matching would greatly release manpower by indicating the known parts coming from different binary programs. Existing approaches mainly focus on function recognition ignoring the recovery of the relationships between functions, which makes the researchers hard to locate the calling routine they are interested in.
