The process of developing embedded software has its own subtleties and complexities though. That is why we decided to tell you more about the concept and the process of creating these systems. Personal data security has become a hot topic in the digital world, where any object connected to the internet can be vulnerable to cyberattacks.

In a hybrid model, symmetric key cryptography is used to validate software integrity and speed the boot code verification process for time-critical startup requirements. Unlike code verified with a public key, the symmetric key must remain secret, known only to the device. Like computers, many embedded systems have security vulnerabilities that can provide a way for a threat actor to gain access to the system.

However, it is important to note that code testing of source code or binary alone will not ensure the system is secure. It will identify security related software bugs, but it will not identify system wide or process related security issues. A smart TV or smartphone can be updated regularly with minimal impact to the end user. In comparison, insecure software in a modern vehicle can put lives at risk, so software updates to vehicles are carefully orchestrated .

In addition to security techniques and security standards, the secure software development lifecycle can help every developer build more secure systems. Embedded system design should always begin with an analysis of the device and its intended and potential unintended usage, security risks and attack surfaces. Security should also be considered at every stage in the SDLC process. A hardware security module or hardware root of trust manages keys, performs encryption and decryption functions, and embeds keys for OS and application use. Often these system-on-a-chip components provide CPU offload for bulk encryption and decryption, and they may also be used to offload network cryptographic functions. Some embedded systems are in the field for decades, others for just a few years.
