Prepping for Q-Day: A Guide to Quantum Readiness

Q-Day refers to the hypothetical day when quantum computers become powerful enough to break current cryptographic methods, rendering many existing encryption methods obsolete.

The National Cyber Security Centre (NCSC) recommends adopting a calm and measured approach to avoid panic-driven and complacent reactions.

The timeline for migrating to post-quantum cryptography (PQC) has three phases: discovery and planning by 2028, early migration by 2031, and full migration by 2035.

PQC reigns supreme over QKD because it can be integrated into existing digital infrastructures with minimal disruption.

The National Institute of Standards and Technology (NIST) has published four standards for key encapsulation and signatures, but the implementation of these standards is still being defined.

Thoroughly audit your IT estate to identify data and assets vulnerable to quantum threats.

Adopting a calm and measured approach to avoid panic-driven and complacent reactions is crucial in preparing for Q-Day.

The Goldilocks Theory suggests that finding the timing that’s just right is crucial in preparing for Q-Day.

Tracking emerging PQC standards from authoritative bodies like NIST ensures businesses stay ahead of the curve.

Business success in the quantum era depends on embracing a calm and clear approach to quantum readiness.
