Adaption of a Privilege Management Infrastructure (PMI) Approach to Industry 4.0

The essential prerequisite for successfully implementing Industry 4.0 is the secure and trustworthy handling of data as well as the reliable protection of cross-company communication against attacks. Confidentiality and integrity are crucial for a secure cyber-physical communication infrastructure. Using a Privilege Management Infrastructure (PMI) is basis to achieve the security objectives. The paper modifies PMI to achieve a scalable access rule management system, with enhancement by introducing trust levels for PMI, associated with extended Attribute Certificates (AC). It further discusses Industry 4.0 challenges and use cases that show the need of the PMI adaption.
