Resilience Talks From Quantum Cryptographic Attacks

 

Post-quantum cryptography (PQC) is a new family of cryptographic algorithms designed to resist quantum computer attacks, and its adoption is crucial for long-term security. However, migrating to PQC poses challenges, such as key and ciphertext size increases, potential performance impacts and the need for updates to public-key infrastructures. 

Hybrid deployments, combining traditional and PQC schemes, offer a solution. They provide a smooth transition, minimizing disruptions and ensuring security during the migration process. This approach is recommended by organizations like the German BSI and French ANSSI, and companies like NXP and Senetas are already working on hybrid solutions.

The hybrid approach to post-quantum security is the use of both the strong assurance of pre-quantum public key algorithms and the resistance against future quantum threats.

The use of hybrid post-quantum solutions allows organizations to experiment with implementing quantum-resistant cryptography without much difficulty, preparing them for the eventual complete migration. Hybrid cryptography is an important strategy for a phased migration to post-quantum cryptography. How long will it take to bring everyone on board?
