Security is crucial to the design of embedded system protocols because it ensures data availability, confidentiality, and integrity during transfer between components. Robust security measures are important to prevent unauthorized access, data breaches, and cyber-attacks. This is particularly true in light of the increasing interconnectivity of embedded systems in critical applications such as industrial control, automotive, and healthcare.
Verification is used in embedded protocols to confirm the identification of connecting devices, integrity checks are used to identify and stop data manipulation, and encryption is used to protect data from eavesdropping. To offer secure communication channels, protocols like TLS (Transport Layer Security) are frequently modified for embedded devices. Firmware updates and secure boot procedures are also used to guarantee that the device can only run authorized software.
An embedded system course offers a strong foundation in both the theoretical and practical aspects of embedded system security for those who are interested in specialising in this field. Topics covered in the course include secure communication protocols, real-time operating systems, and microcontroller programming.
