I attended the International Conference on Historical Cryptology in June 2022. The conference took place in Amsterdam and was the first real conference, after the previous two HistoCrypts’ live events (2021 in Amsterdam and 2020 in Budapest) unfortunately had to be canceled due to the ongoing COVID-19 pandemic.
HistoCrypt 2022 was a great conference organized locally by Karl de Leeuw, a good colluege and great researcher who sadly passed away only three weeks after the conference in Amsterdam.
The conference featured 9 tracks, each track covering a different main topic, like crypto machines, historical documents, or machine learning. I had the opportunity to present together with Michelle Waldispühl our work about deciphering encrypted letters sent and received by Holy Roman Emperor Maximilian II in 1574 and 1575. Also, I was able to showcase CrypTool 2 in the poster session (I published a paper about new components in CrypTool 2). Jörgen Dinnissen presented our paper about a cipher of the Dutch East India company from 1674. Nino Fürthauer talked about our work with solving transposition ciphers using machine learning and Beáta Megyesi presented our work on analyzing thousands historical encryption keys.
All Talks Summarized in a YouTube Video
Today, I also created a YouTube video summarizing all talks given at HistoCrypt. You can watch it here:
