Current trends like Cloud Computing dissolve the known structure of the automation pyramid and lead towards a higher level of connectivity between different networks. Classical security methods like separation do not necessarily yield the needed level of protection. This paper describes the evaluation of a new security layer to protect the PROFINET communication by cryptographic means under real-time...
This paper introduces a concept and a software prototype for a distributed supervision of Ethernet based Automation Components. First an introduction shows the focus of this paper followed by relevant IT security basics in this context. Further, main requirements for creating a distributed supervision concept are shown. Here digital signatures and methods of checksums are used. Finally, the software...
