In this paper, we propose a security architecture for a gateway connecting production and cloud systems. A Trusted Platform Module 2.0 is used for protecting the cryptographic keys used in secure communication protocols and to provide protection against illegitimate firmware manipulation. As proof of concept, we implemented the key protection functionality with a TPM 2.0 for the OPC UA protocol.enIndustrial cyber-physical systems securityGateway securityOpen Platform Communications Unified Architecture (OPC UA) securityTrustworthy systemsIndustrial Internet of ThingsMeasured bootTrusted Platform Module004005conference paper
