Abstract
The requirements regarding network management
defined by the continuously rising amount of interconnected de-
vices in the industrial landscape turns it into an increasingly
complex task. Associated by the fusion of technologies up to Cyber-
Physical Production Systems (CPPS) and the Industrial Internet
of Things (IIoT) with its multitude of communicating sensors and
actuators new demands arise.
In particular, the driving forces of this development, mobility
and flexibility, are affecting today’s networks. However, it is pre-
cisely these wireless solutions, as enabler for this advancement,
that create new attack vectors and cyber-security threats.
Furthermore, many cryptographic procedures, intended to secure
the networks, require additional overhead, which is limiting the
transmission bandwidth and speed as well. For this reason, new
and efficient solutions must be developed and applied, in order to
secure the existing, as well as the future, industrial communication
networks.
This work proposes a conceptual approach, consisting of a combi-
nation of Software-Defined Networking (SDN) and Physical Layer
Security (PhySec) to satisfy the network security requirements.
Use cases are explained that demonstrate the appropriateness of
the approach and it is shown that this is a easy to use and resource
efficient, but nevertheless sound and secure approach.
