Cybersecurity for Embedded Systems: A review

Encryption is the process of encoding the sensitive data so that only authorized parties or personnel can access it. Without encryption, some critical data or information would be at risk. Manufacturers and system developers are searching for better ways to protect its property using different security implementations. An embedded system need to run only authorized firmware. In this paper, we present some basic types of code protection together with a hardware based implementation that can be easily applied for an appropriate level of cybersecurity in embedded projects.
