In the future, Quantum computers will be able to break today's asymmetric cryptography, especially RSA, CC and DH variants. This would lead to a catastrophic situation sometimes called "Quantum Apocalypse". To avoid such situation, the cryptographic community started, quite a long time ago, works on new replacement algorithms, based on other mathematical properties, and which are called "post-quantum algorithms" (or quantum-safe algorithms).
Those new algorithms, while providing a solution for the Quantum threat, also comes with new various challenges to address: different usage constraints, size of keys/data, how to implement them in a secure
way, ......
In this session, we'll have a quick reminder of the Quantum threat, the post-quantum algorithms, the challenges to address, then we'll see the updated state of the post-quantum transition, from strategy guidelines to latest algorithm and protocols updates and implementations.
Then, we'll see some examples of what steps of this post-quantum transition can already be done in 2026, especially with Open Source tools, and what are the potential caveats and risks.
