Abstract: Systems and methods for performing binary translation include a system that is capable of translating binaries written for use in a source execution environment to binaries compatible with a target execution environment. Consistent with some embodiments, a binary translation system includes a system service and a runtime code module that exists in an application memory address space. The binary translation system translates object-level binaries corresponding to executables, linkers, libraries, and the like and stores the translation in a translation cache that is cryptographically secured to ensure that only a system having a specific key is able to access the translations. If the application or application binary has been modified since the translation was performed, the system service will ensure that the translation is removed from the cache, a new translation is performed, and all threads accessing that translation are updated to the new translation.
