Prof. Alexander Wiesmaier is guest at the House of Nerds. He talks to us about the basics of encryption and how it works. He also explains how to keep encryption up to date in our systems, keyword crypto-agility, despite the looming threat of quantum computers and the aging process of all encryption algorithms, whether classic or newly developed post-quantum algorithms. Finally, we take a small detour to applied data protection: how can individuals actually get a complete overview of their personal data? Who actually has what data? And how do you find out? Prof. Wiesmaier has an interesting research approach here.
