Symposium Series on Post-Quantum Cryptography

Post-Quantum Cryptography

Cryptography is at the heart of internet security. However, much of the currently deployed cryptography is vulnerable to quantum attacks, which will become effective once large-scale quantum computers become feasible. Therefore, the affected cryptographic standards must be replaced by ones that offer security against quantum attacks. The post-quantum cryptography transition may take organizations ten years to complete, or longer. To remain secure and comply with legal and regulatory requirements, affected organizations should act now. What do you need to know - and what can you do - in order to continue your course of business securely?

Symposium Series

The Symposium Post-Quantum Cryptography is part of a series organized by CWI Cryptology Group and TNO. The symposium is aimed at higher management and security professionals from government, private sector, and industry. The first symposium in April 2021 was a general introduction to the problem from the perspective of industry, government, and end user. The second episode of November 2021 zoomed in on a number of specific topics, including quantum-safe PKI, the relation between PQC and QKD, and PQC standards & implementation.
