While security protections continue to be developed for general-purpose computers,real-time computing has remained unprotected against control-flow hijacking attacks.Existing solutions rely on hardware unavailable to embedded systems due to the cost, or impose excessive overhead, leaving real-time applications unable to operate within their time constraints. We propose RECFISH++, a Control-Flow Integrity implementation focused on protecting real-time embedded systems. By modifying LLVM and FreeRTOS, a popular compiler back-end and real-time operating system, we provide an end-to-end solution for protecting any real-time application on the ARM Cortex-M microprocessor against control-flow hijacking attacks.
