The prospect of large-scale quantum computers necessitates the design, development, and standardization of post-quantum cryptography (PQC). Industrial control systems (ICS) and critical infrastructures are expected to be among the first industrial environments to adopt PQC. As their components have a long life span (≥ 10 years) and are increasingly interconnected to form an Industrial Internet of Things (IIoT), they require strong and long-lasting security guarantees. Because of these high-security requirements, IIoT products are also increasingly equipped with additional hardware security elements — often Trusted Platform Modules (TPMs).
