In the field of computer science, communications protocols (such as computer network protocols) are hardened (secured) against reverse engineering attacks by hackers using a software tool which is applied to a high level definition of the protocol. The tool converts the definition to executable form, such as computer source code, and also applies reverse-engineering countermeasures to the protocol definition as now expressed in source code, to prevent hackers from recovering useful details of the protocol. This conversion process also allows preservation of backwards version compatibility of the protocol definition.
