Why waiting for quantum computers to arrive could leave your security exposed

An organisation that understands its cryptographic dependencies is better prepared to respond when standards change, algorithms are retired or vulnerabilities emerge.

Post-quantum cryptography is exposing a broader resilience issue: organisations need to become better at changing cryptography.

Post-quantum algorithms have moved beyond academic research into published standards and real implementations.

The mathematics behind post-quantum cryptography is different from the mathematics underpinning established approaches such as RSA and elliptic curve cryptography.

We still cannot say when a quantum computer capable of breaking today’s cryptography will arrive.
