What is post-quantum cryptography (PQC)?
Post-quantum cryptography, PQC consists in all cryptographic methods that withstand a quantum computer. Nearby on the computing horizon there will be quantum computers capable of factorizing large prime number products and solving the discrete logarithm problem.
This will enable quantum computing to break the existing asymmetric cryptography methods currently used to secure our data (RSA, ECC and Diffie-Hellman), and thus put at great risk the way we do and secure digital business.

Atos helps you benefit from quantum computing, while also anticipating the threats it creates towards your cybersecurity, by preparing and planning your migration to post-quantum cryptography.
To migrate to PQC smoothly and effectively, you can leverage and benefit from our full set of crypto-agile products to secure your perimeter: from generating secure key pairs to deploying them through a PKI to using them in tokens and applications to secure your network and data. By supporting you in deploying crypto-agile solutions, we ensure an easy switch between cryptographic methods including new quantum safe ones. For now, most authorities recommend an hybrid approach adding a quantum-proof layer of security on top of the current traditional cryptographic protocols already in use. This ensures that if one layer is broken the second one remains. Adopting hybrid security now also protects all your assets from being stored and decrypted later on, once quantum computers become available to attackers.
The rise of quantum computing implies that staff will have to be trained on PQC topics and technologies.
Atos supports organizations in understanding and adopting this technology thanks to top experts in the field of both quantum computing and PQC.
