LERNZIELE
The students understand the concepts of physical-layer measures to achieve secrecy.Equipped with tools and methods acquired during the lectures, new setups can be investigated.
INHALT
The broadcast nature of wireless systems makes it more vulnerable to eavesdroppersto extract data from the received signals. The conventional way to achieve confidentiality is
by using cryptographic encryption based on keys. The idea behind is that the eavesdropper
is assumed to have limited time or computational resources. While this approach has both
it advantages and disadvantages, the physical-layer approach can be regarded as a powerful
alternative or as an additional level of protection to achieve security in wireless networks. A
distinct feature of the physical-layer approach is that the eavesdropper is assumed to have
unlimited time and resources available. Furthermore, this approach guarantees both reliability
and security, which the other approach can not. In this lecture, we will cover the following
aspects and setups
