METHOD TO SECURE EMBEDDED SYSTEM WITH PROGRAMMABLE LOGIC, HARDWARE, AND SOFTWARE BINDING, EXECUTION MONITORING, AND COUNTERACTION

摘要

Systems and methods for securing an embedded system are disclosed. An embedded system comprises a hardware subsystem including physical components of the embedded system, a software subsystem including a software application and a program code, and a programmable logic subsystem programmed to monitor one or more parts of the hardware and software subsystems and interactions thereof to detect tampering of the embedded system. The programmable logic subsystem is capable of being activated by a security function in the software subsystem or by a special hardware component in the hardware subsystem. The activation of the programmable logic subsystem facilitate a coupling of the hardware, software, and the programmable logic subsystems. The program code can be used to dynamically re-program the programmable logic subsystem.
