Malicious hardware is a fairly new research topic that has attracted the interest
of the scienti c community. Therefore, numerous approaches have been proposed
in the last years to counter the threat of so-called
hardware
Trojans
. This chapter
describes malicious hardware in the context of the security of hardware infrastruc-
ture components. Network infrastructure plays a vital role in our everyday lives,
since many services depend on reliable and secure connections. In the following, we
brie y introduce the topic of hardware
Trojans
. After describing their basic compo-
nents, we give some insights into how hardware
Trojans
can be used maliciously in
infrastructure devices. Furthermore, we outline the evolution of hardware
Trojans
and measures to counter them
