Industrial Cyber-Physical Systems require appropriate security mechanisms to provide protection against cyber attackers. 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.
