Trusted Semiconductor Supply Chains: The Foundation of Post-Quantum Security

As quantum computing moves from research labs to commercial reality, cybersecurity is entering a new chapter.

Much of the discussion around the quantum transition has focused on new cryptographic algorithms and the migration to Post-Quantum Cryptography (PQC). While software migration is essential, it represents only part of the challenge.

The future of digital trust will also depend on something far more fundamental: the security of the hardware itself.

Every connected device—from industrial control systems and smart grids to vehicles, healthcare equipment and defense platforms—ultimately relies on silicon as its root of trust. If that foundation cannot be trusted, no software update or encryption protocol can fully compensate.

This is why trusted semiconductor ecosystems and resilient supply chains are rapidly becoming strategic priorities for governments, industries and technology providers worldwide.

Security Begins at the Silicon Level

Hardware Root of Trust technologies provide the secure foundation upon which digital identities, secure boot, authentication and encrypted communications are built.

As organizations prepare for the quantum era, these trusted hardware components must evolve to support quantum-resistant cryptography while maintaining the highest levels of certification, reliability and scalability.

At the same time, growing government initiatives and industrial strategies focused on secure semiconductor manufacturing have reinforced another reality: where and how semiconductors are designed and manufactured matters just as much as the technologies embedded within them.

Trusted manufacturing, certified security IP, resilient supply chains and secure hardware architectures are becoming essential components of national cybersecurity strategies and next-generation digital infrastructure.

Building Resilience for the Post-Quantum Era

Preparing for quantum computing requires more than replacing today's cryptographic algorithms.

It requires an integrated approach that combines:

• Secure semiconductor design
• Post-Quantum Cryptography implementation
• Trusted manufacturing
• Certified security IP
• Long-term hardware roadmaps capable of evolving alongside future standards

Only by addressing both hardware and software can organizations achieve long-term resilience against emerging quantum threats.

Collaboration Is Accelerating Innovation

No single company can build the post-quantum ecosystem alone.

The transition to quantum-resilient infrastructure depends on collaboration between semiconductor manufacturers, security technology providers, system integrators and research organizations.

By bringing together complementary expertise, these partnerships accelerate the path from innovation to industrial deployment while ensuring interoperability, certification and commercial scalability across multiple markets.

More importantly, they help strengthen trusted semiconductor ecosystems capable of supporting critical infrastructure, AI, defense, industrial IoT and the next generation of secure digital services.

A Shared Vision for Trusted Silicon

The recently announced strategic partnership between SEALSQ and GlobalFoundries reflects this broader industry evolution.

By combining GlobalFoundries' advanced manufacturing expertise with SEALSQ's secure semiconductor technologies and Post-Quantum Cryptography expertise, the collaboration aims to accelerate the development of next-generation secure integrated circuits, certified PQC security IP, secure chiplet architectures and CryoCMOS technologies for future quantum computing applications.

More importantly, it reflects a shared commitment to strengthening trusted semiconductor ecosystems capable of supporting secure digital infrastructure throughout the AI and quantum era.

As quantum computing continues to advance, trust will increasingly be built not only through stronger algorithms, but through secure hardware, trusted manufacturing and long-term collaboration across the semiconductor industry.

The post-quantum future starts at the silicon level.
