 # Overview
 CPC Aggregation by Reversing and Dumping in Arrays Lightweight (CARDINAL) is a tool that can find similarities between binaries compiled with different optimization flags, or even completely different compilers. CARDINAL accurately finds the number of arguments at each callsite, also known as the callsite parameter cardinalities (CPC's), and creates a easily comparable signature by aggregating them per function and dumping the result into a Bloom filter. Bloom filters are compared via the Jaccard index from which a similarity score is calculated. CARDINAL is proven to tolerate differences between binaries produced using the same source but different compiler configurations, from using different optimization levels to using completely different compilers. We hope that CARDINAL paves the way for future static analyses that similarly tolerate radical code transformations like a dynamic analysis, yet still retain the benefits of static analysis.
