Q-PrEP is about to bring together national and EU cyber security organizations, providers of technical solutions from the public sector, and all branches of public administration affected by exchange of sensitive information. The thematic focus is on the Post-Quantum Cryptography (PQC) as the most practical & mature approach to adapt state-of-the-art conventional encryption standards to the consequences of fast evolving Quantum Computing (QC) – to ensure that private sensitive information from the public sector stays private in future, too.
