SYNTHESIS LECTURES ON INFORMATION SECURITY PRIV...

In our digital world  integrated circuits are present in nearly every moment of our daily life.
Even when using the coffee machine in the morning  or driving our car to work  we interact with
integrated circuits. The increasing spread of information technology in virtually all areas of
life in the industrialized world offers a broad range of attack vectors. So far  mainly
software-based attacks have been considered and investigated  while hardware-based attacks have
attracted comparatively little interest. The design and production process of integrated
circuits is mostly decentralized due to financial and logistical reasons. Therefore  a high
level of trust has to be established between the parties involved in the hardware development
lifecycle. During the complex production chain  malicious attackers can insert non-specified
functionality by exploiting untrusted processes and backdoors. This work deals with the ways in
which such hidden  non-specified functionality can be introduced into hardware systems. After
briefly outlining the development and production process of hardware systems  we systematically
describe a new type of threat  the hardware Trojan. We provide a historical overview of the
development of research activities in this field to show the growing interest of international
research in this topic. Current work is considered in more detail. We discuss the components
that make up a hardware Trojan as well as the parameters that are relevant for an attack.
Furthermore  we describe current approaches for detecting  localizing  and avoiding hardware
Trojans to combat them effectively. Moreover  this work develops a comprehensive taxonomy of
countermeasures and explains in detail how specific problems are solved. In a final step  we
provide an overview of related work and offer an outlook on further research in this field.
