Abstract

Systems and methods are disclosed for providing stack overflow protection on a system on chip via a hardware write-once register. An exemplary embodiment of an system on chip comprises a hardware write-once register, a boot processor, and one or more processor subsystems. The boot processor is configured to execute a read only memory (ROM) image which initializes the hardware write-once register with a first numeric value in response to the system on chip being powered on. The one or more processor subsystems have an associated software image configured to use the first numeric value in the hardware write-once register as a stack canary value to combat stack overflow attacks.
