The International Conference on Historical Cryptology (HistoCrypt 2021, website: https://histocrypt.org/2021/) invites submissions of papers to its annual conference on historical cryptology. The conference will be held in September 20-22, 2021, at the Royal Netherlands Academy of Sciences (KNAW) in Amsterdam, Netherlands. Please mark your calendars.

HistoCrypt addresses all aspects of historical cryptography and cryptanalysis. The conference's subjects include, but are not limited to:

  • the use of cryptography in military, diplomacy, business, and other areas
  • analysis of historical ciphers with the help of modern computerized methods
  • unsolved historical cryptograms
  • the Enigma and other encryption machines
  • the history of modern (computer-based) cryptography
  • special linguistic aspects of cryptology
  • the influence of cryptography on the course of history
  • teaching and promoting cryptology in schools, universities, and the public

We welcome everybody interested in the field of historical cryptology to participate in the event. We invite submissions to HistoCrypt for presentation at the conference, which will be evaluated by a program committee. Participation in the conference is mandatory for at least one author of each accepted paper.


HistoCrypt 2021 represents a continuation of the highly successful European Historical Ciphers Colloquiums (EuroHCC) held in Heusenstamm (2012), Kassel (2016), and Smolenice (2017). Considering EuroHCC's growing popularity among the crypto historians and cryptographers, we established HistoCrypt as an annual, international event. The first event in the series took place at Uppsala University, Sweden in 2018, the second event was held at the Mundaneum in Mons, Belgium in 2019. Due to the circumstances, the third event at Eötvös Loránd University in Budapest, Hungary in 2020 could not take place as physical meeting, but the proceedings were published.


We invite paper submissions in two distinct tracks:

  • regular papers up to 10 pages (including references) on substantial, original, and unpublished research, including evaluation results, where appropriate;
  • short papers up to 4 pages (including references) on smaller, focused contributions, work in progress, negative results, surveys, tutorials, or opinion pieces;

Presentations of accepted papers are either oral, poster, or demo, which will be decided by the program committee.

Papers accepted for presentation at the conference will be included in the HistoCrypt 2021 proceedings, which is published as part of the Northern European Association for Language Technology (NEALT) Proceedings Series (http://omilia.uio.no/nealt/?task=publications) by Linköping University Electronic Press (ECP: https://www.ep.liu.se/ecp/index.en.asp), as freely available Gold Open Access. Publications in the Linköping Electronic Conference Proceedings are ranked on the Norwegian register for scientific journals, series and publishers as Level 1 publications. Please consult the responsibilities of the authors concerning publication ethics and malpractice statement as described on the ECP website: https://www.ep.liu.se/ecp/index.en.asp#tab4. Paper submissions that violate these requirements will be returned without review.

Covid-19 situation

We will try hard to arrange a physical meeting, but due to global uncertainties about travel and contact restrictions in 2021, we cannot guarantee that it will take place. Should circumstances beyond the control of the organizers make the physical meeting impossible, the organizers shall undertake every reasonable effort to implement the conference as a virtual meeting. Should this prove to be impossible, the organizers reserve the right to cancel this edition of the conference, publishing the accepted papers in the proceedings. News will be posted on the website.
