Data and network security have become of utmost importance in today's highly interconnected world. Embedded systems security is a great research area at the core of any secure cyber-infrastructure, with unique challenges: Besides classical problems found in security, systems must meet tough constraints on power consumption, interoperability and cost. At the same time, adversaries may have physical access to the system, allowing them to perform a whole new class of attacks. The sum of these challenges is what makes work in embedded systems security so fascinating. Building secure systems does not only require a good understanding of the involved algorithms and protocols. Being able to approach solutions from the viewpoint of a malicious adversary is also of high importance. Vulnerability research is an integral tool for security architects, and is an exceptional style of thinking that that goes beyond classical engineering skills. In embedded security, students do not only learn this way of thinking at an early stage, they can also work on cutting-edge research problems.
