Multi-Partner Project: Quantum-Secure IoT-based Digital Manufacturing Pilot in QUBIP project

Abstract

Connectivity has become essential to modern manufacturing, but it also introduces new security challenges. Industrial IoT ecosystems rely on public-key cryptography to protect communications, firmware, and operational data. However, the emergence of quantum computing threatens to undermine these cryptographic foundations, exposing long-lived manufacturing systems to future attacks. This paper presents the Quantum-Secure IoT-based Digital Manufacturing Pilot, developed within the EU-funded QUBIP project, which investigates the integration of post-quantum cryptography (PQC) into IoT environments. The pilot aims to demonstrate how quantum resistant algorithms can be efficiently deployed across heterogeneous devices with limited resources to ensure data exchange and authentication. By combining software and hardware-based approaches, the proposed pilot provides a replicable model for PQC migration in digital manufacturing, ensuring long-term data integrity and resilience in the quantum era.
