In modern industrial production lines, the integration and interconnection of various different manufacturing components, like robots, laser cutting machines, milling machines, CNC-machines, etc. allows for a higher degree of autonomous production on the shop floor. Manufacturers of these increasingly complex machines are beginning to equip their business models with bidirectional data flows to other factories. This is creating a digital, cross-company shop floor infrastructure where the transfer of information is controlled by digital contracts. To establish a trusted ecosystem, the new technology "blockchain" and a variety of technology stacks must be combined while ensuring security. Such blockchain-based frameworks enable bidirectional trust across all contract partners. Essential data flows are defined by specific technical representation of contract agreements and executed through smart contracts.This work describes a platform for rapid cross-company business model instantiation based on blockchain for establishing trust between the enterprises. It focuses on selected security aspects of the deployment- and configuration processes applied by the industrial ecosystem. A threat analysis of the platform shows the critical security risks. Based on an industrial dynamic machine leasing use case, a risk assessment and security analysis of the key platform components is carried out.
The aim of this bachelor thesis is to research a way to implement mobile work successfully into the department of IDS Sales Service at Roche Diabetes Care Germany GmbH. To achieve this objective, a literature review was done that identifies the most expected threats and determines strategies to overcome them. In the practical part, the tasks in the department in question are categorized and it is analyzed which threats are most significant in this case. Further, using the outcomes of a department survey and pilot days, policies are formulated to reduce these probable threats and to define the terms and conditions of the arrangement. Due to the findings in this thesis, mobile work was successfully implemented into the department of IDS Sales Service.
