Beyond cryptographic algorithms, the security of the digital supply chain is a critical vulnerability point that quantum computing could exacerbate. Hardware and software components, from chips to operating systems, can be compromised at various stages of their lifecycle, introducing backdoors or weaknesses that quantum adversaries could exploit. The US strategy heavily emphasizes securing the supply chain to prevent such compromises.

This involves a comprehensive approach to vetting components, ensuring integrity from design to deployment. The goal is to build trust in the underlying technology that will host quantum-resistant solutions. Without a secure supply chain, even the strongest PQC algorithms could be undermined by compromised hardware or software.

Key Initiatives in Supply Chain Security

To address these challenges, the US government is implementing several key initiatives. These include establishing stringent procurement standards, fostering domestic production of critical components, and developing advanced methods for hardware and software attestation.
