Abstract
Post-quantum cryptography does not arrive as a clean replacement for today’s systems. It forces organizations to rethink how cryptography is designed, deployed, governed, and maintained over time. In this special episode of Shielded, host Jo Lintzen leads a discussion that moves past algorithm selection and into operational reality. The panel connects three pressures most organizations underestimate. Threats evolve quickly. Hardware and deployed systems last for years. Governance around cryptographic assets is often weak or incomplete.
Bill Buchanan, Professor Edinburgh Napier University explains how lattice-based cryptography enables new capabilities such as fully homomorphic encryption, where data remains encrypted even while being processed. This matters in modern environments shaped by cloud platforms, edge computing, and machine learning, where sensitive data is frequently exposed during computation.
Mamta Gupta Lattice Semiconductor highlights the growing mismatch between long hardware lifecycles and rapidly changing cryptographic requirements. Devices expected to remain in the field for a decade must soon meet post-quantum mandates, even as standards and certification frameworks continue to evolve. Locking in rigid choices today creates future risk.
Jeremy B, NIST focuses on the skills gap. Post-quantum migration requires experienced practitioners, structured discovery, and repeatable methods. Until those capabilities become widespread, organizations must treat PQC work as specialized and plan accordingly.
Adrian Neal, Capgemini delivers a warning about failure modes. New algorithms will not tolerate weak governance or poor implementation. The most dangerous outcome is silent failure, where systems appear secure but provide little real protection.
Yolanda Reid, former Associate Director IBM reframes the issue for leadership. This is not another Y2K-style event. Cryptography will continue changing for the lifetime of modern systems. Executives must understand the risk to their most valuable assets and support long-term operating models, not short-term fixes.
Bruno Couillard, Crypto4A Technologies closes by challenging decades of assumptions. For thirty years, digital systems were built on the belief that cryptography should never change. That belief no longer holds. Security now depends on knowing what cryptography is used where, maintaining it continuously, and building teams capable of adapting as standards and threats evolve.
