Development and Implementation of a Public Key

Infrastructure for Industrial Environments


As one of the leading resarch institutes for applied and integrated security, Fraunhofer AISEC operates laboratories in the field of industrial security. To analyze the security of production processes, one of our laboratories is equipped with a fully functional production line including mobile robot systems, allowing to investigate realistic threats and conduct corresponding attacks. The used components range from an integrated web shop over the control station down to the level of programmable logic controllers (PLCs), sensors, and actors.


The goal of this thesis is to develop and implement a public key infrastructure (PKI) aiming to provide the various components of our production line with digital certificates used for different purposes.

The first step for this is to identify and document existing (interfaces for the integration of) digital certificates within the production line’s different components along with their respective use case. The second step is the development of a detailed concept in accordance with the standard IEC 62443. In the third and last step, the concept has to be implemented and evaluated by issuing certificates and using them for a specific use case.

Due to the production line’s physical setup and the empirical nature of some of the tasks, on-site presence in our institute in Garching is necessary. Please consider this fact before submitting your application. The conceptual parts of the work can be composed remotely, however.


  • Self-initiative and the ability to work in a self-directed way

  • Knowledge in the field of IT/OT/ICS security

  • Basic programming abilities

  • First experiences with automated and interconnected industrial environments (Industrie 4.0)

    and/or digital certificates / PKIs would be ideal but are not a must
