Pursuing the Vision of Industrie 4.0: Secure Plug-and-Produce by Means of the Asset Administration Shell and Blockchain Technology

The Plug-and-Produce concept requires that after connecting a new module to a system, the exchange of the configuration data takes place. As further operation of the system depends on this initialization procedure, it is necessary to ensure that the data presented by the system and the newly attached component is authentic. Therefore, we propose a new concept for secure Plug-and-Produce functionality, which exploits the combination of the Asset Administration Shell (AAS) and Blockchain technology. On the one hand, the AAS shall be responsible for presenting uniform and standardized configuration data as well as for storing and managing Blockchain. On the other, Blockchain shall ensure authenticity and integrity of the configuration data.
