In this segment from DigiCert World Quantum Readiness Day, Luke Valenta, research engineer at Cloudflare, Martin Reilly, digital identity operating manager at DXC Technology and Deepika Chauhan, chief product officer of DigiCert, join theCUBE’s John Furrier for "The Quantum Dispatch." The panel explores practical lessons learned from the forefront of post-quantum cryptography (PQC) migration and the "customer zero" journey. The speakers detail how internal implementation and open collaboration are essential for building the frameworks necessary to protect critical IT systems against future quantum threats. The conversation dives into the complexities of creating a cryptographic inventory – the "step zero" for any migration – and the technical hurdles of deploying NIST-standardized algorithms like ML-KEM. From addressing the "store now, decrypt later" threat model to overcoming middle-box bugs caused by larger packet sizes, the experts share a roadmap for achieving true crypto agility. They emphasize that PQC readiness is not a one-time fix but a continuous organizational muscle required to maintain digital trust as global standards and quantum capabilities evolve.
