For a long time, the main concern of the security community were traditional computer networks. The next generation of "computer" networks will look different: your clothes might talk to your car, while your handheld talks to the refrigerator. DRM in mobile devices or IP protection in game consoles are other important security applications. Many embedded applications will have security solutions which are different from, say, building firewalls for a corporate network.

In contrast to classical IT security, providing security for embedded devices is heavily dependent on the target's hardware and software. For instance, perfor-ming a digital signature can be a major challenge for an RFID bar code label. We will give an overview about this emerging area. As case studies, we will discuss extremely lightweight security for component identification (e.g., for printer cartridges), and "network" security for automotive adhoc networks.
