8 Conclusion

As automotive and industrial real-time control systems become more complex and interconnected, cybersecurity threats continue to increase in scope and ingenuity. The modern threat landscape therefore drives a demand for more stringent cybersecurity features in real-time microcontroller products, without compromising loop processing performance. Texas Instruments C2000™ F29x and Sitara™ AM26x microcontrollers meet this need, enabling embedded designers to build highly secure real-time control systems for modern applications. These products include an embedded Hardware Security Manager (HSM) that provides firmware protection, secure debug authentication, secure storage, and modern cryptographic functions. Secure provisioning of user encryption keys and code, secure boot, and secure firmware update features can be used to establish a root of trust, and maintain the confidentiality and integrity of user code and assets. Additionally, the unique architecture of the TI C29x CPU enables dynamic context-aware security for applications during run-time, extending the concept of a secure execution environment beyond the boundaries of the HSM. Using this run-time security model, externally facing application functions such as communication stacks can be isolated from critical system functions, mitigating the risk to the overall safety and security of the system posed by outside threats. With this complete platform security solution, users can develop high-performance real-time control systems that meet the highest cybersecurity standards.
