The Corona break was long, but since autumn 2021 trade fairs and congresses have been held again in the computer industry. Also cryptovision is happy about this piece of regained normality. Last week cryptovision employee Klaus Schmeh took the opportunity and made his way to Berlin for a lecture. At the Signaturtag, organized by TeleTrusT and VOI, he gave a presentation on the topic “The three most important post-quantum signature procedures explained clearly”.

Schmeh’s goal of making the subject of post-quantum cryptography understandable to laypersons is no easy task, because the various procedures are mathematically extremely demanding. In the meantime, it has become clear which of the many dozens of post-quantum methods will prevail in practice. Among the favorites are also five signature methods that have already been standardized or have reached the final round in the post-quantum competition of the U.S. authority NIST. Schmeh presented three of these algorithms in his talk.

For his presentation, the long-time cryptovision employee used, as usual, his original slides in cartoon design and vivid analogies from everyday life. Even listeners without a mathematics or computer science degree got an idea of how CRYSTALS-DILITHIUM, Rainbow or extended Merkle signatures work.

After the successful start, the trade fair and congress autumn continues for cryptovision. From October 12 to 14, it-sa in Nuremberg is on the agenda.
