Post-Quantum Cryptography (PQC) deals with the design of cryptosystems that are secure even in the presence of a quantum adversary. This is a rather classical academic topic that shifted a few years ago to a theme of major industrial interest. This is mainly driven by the fact that US NIST started a process, the so-called NIST PQC standardization process, whose goal is to define post-quantum public-key standards.
The NIST PQC process is now reaching a final step that will mark a new step in the wide deployment of PQC. In this talk, we will overview the NIST PQC results, describe deployments of PQC in real use-cases, and will discuss some theoretical and practical challenges in PQC.
