Post Quantum Transition

Upgrading Systems with Post-Quantum Cryptography

As the threat of quantum computing grows, businesses and organizations need to start planning for the post quantum transition. This means migrating their processes and applications to use post quantum cryptography, which is resistant to attacks by quantum computers.

Organisations like the German Federal Office for Information Security (BSI) and the French National Agency for the Security of Information Systems (ANSSI) recommend to start using quantum safe cryptography as soon as possible.

Our Services

Cryspen offers comprehensive consulting services to help you with your post-quantum transition. We identify cryptography and protocols you use today that will need to be upgraded and recommend a roadmap for migration. We will also help you implement the necessary changes and offer ready to use protocol stacks and primitives to integrate into your applications and products.

PQ Transition Process

Our Software

With libcrux Cryspen maintains and develops a cryptographic library that includes post-quantum safe primitives. The library is integrated into protocols like HPKE and MLS, and can be easily integrated into other libraries like TLS.

Our Team & Commitment

We have a team of experienced security and cryptography engineers and researcher with deep knowledge of post quantum cryptography and its deployment. We are committed to helping you protect your business and applications from quantum attacks and will work with you every step of the way to ensure a smooth and successful transition.
