Post-Quantum Cryptography (PQC)
Post-Quantum Cryptography is the class of cryptographic methods designed to remain secure against attacks from both classical and quantum computers. As quantum computing advances, many of today’s widely used public-key systems, especially those based on RSA and elliptic-curve cryptography, face a long-term risk of becoming vulnerable. PQC addresses this challenge by replacing these exposed mechanisms with new algorithms built to resist quantum attacks while remaining compatible with existing digital infrastructure.
Practical migration
For most organizations, PQC is the most immediate and practical step in the transition toward quantum-safe security. It can often be introduced without replacing entire networks or rebuilding operational environments from scratch. Instead, it enables a controlled migration of cryptographic components across applications, communication systems, identity layers, and security architectures. This makes PQC a central pillar of any realistic quantum-readiness strategy.
How Quantum B works with PQC
Quantum B helps organizations approach PQC not as a theoretical standards exercise, but as an implementation challenge that affects architecture, interoperability, performance, compliance, and long-term resilience. We support clients in selecting appropriate approaches, integrating them into operational systems, and aligning PQC adoption with broader migration frameworks such as QCMS. The goal is not only to deploy new algorithms, but to ensure that the transition is secure, manageable, and strategically sound.
