Securing embedded systems with digital signatures: The basics

Securing an embedded system is incredibly important and having a digital signature plays a crucial role in that. A digital signature confirms that a specific piece of information came from a specific organization (i.e. the one with the private key as described below) and has not been modified.

Follow-up articles will firstly cover related issues such as how to secure and handle your private key, why this is so important, and how SEGGER does it. After that, articles will address how digital signatures are applied to solve particular problems, who stands to benefit, and what the costs are.

This article discusses the basic principles of how to secure your embedded system.

Saving power in embedded systems – Reducing idle CPU speed

Dynamic power, meaning power consumption that is proportional to a clock speed, is a significant part of the power usage of a computer system. Reducing CPU load is one way to reduce this. More interestingly, reducing CPU clock speed in idle mode is another way. And there is hardly any downside!

emWeb: User interface in the web browser

Recently at SEGGER, we released a brand new product: the Flasher Hub. During development it became clear that the Flasher Hub needed an easy user interface for monitoring and configuration. The device itself is headless: No display and limited resources. Years of experience with web interfaces used in our J-Links and Flashers made our decision easy. […]

Risks Are Often Underestimated — It Is Not Only the Chip Crisis that Threatens Embedded Manufacturers

With the chip crisis and the standstill of assembly lines in the automotive industry, supplier management has become a hot topic. Beyond the repeated shortage of semiconductors, there are other risks worth taking into consideration when selecting suppliers. The quality of a supplier for embedded hardware and software can determine the success or failure of […]
