The availability of multiple binaries built from the same sources creates new challenges and opportunities, and raises questions such as: “Does build A confirm the integrity of build B?” or “Can build A reveal a compromised build B?”. We introduce levels of equivalence, inspired by clone detection types, and demonstrate the value of these new levels through several experiments. For this purpose, we construct a dataset consisting of Java binaries (jar files) built from the same sources independently by different providers, resulting in 14,156 pairs of binaries in total.
