A new perspective on Dutch WWI codebreaking with its international ramifications
(Tartu University Library, 2024) Jacobs, Bart; van Kampen, Florentijn; Waldispühl, Michelle; Megyesi, Beáta
During the First World War, the Netherlands maintained a stance of carefully guarded neutrality. International tele communications in the form of telephone and telegraph were closely monitored and censored by so-called censorbureaus. In 2019 new files were declassified and released to the Dutch National Archive about the secensorship bureaus at Amsterdam and Rotterdam, covering 1914 to 1918. They provide detailed insight in the day-to-day business, the codebreaking efforts and specific cryptanalytic results. The material provides a completely new perspective on the genesis of modern Dutch codebreaking. This article gives a first survey of the development of these interception bureaus. It analyses their pioneering codebreaking activities and presents historic material on German diplomatic ciphers. Also, it provides new insight into the mysterious sale in 1919 of German codebooks from the Netherlands to the United States, as reported earlier in the literature.

A Typology for Cipher Key Instructions in Early Modern Times
(Tartu University Library, 2024) Megyesi, Beáta; Láng, Benedek; Kopal, Nils; Mikhalev, Vasily; Tudor, Crina; Waldispühl, Michelle; Waldispühl, Michelle; Megyesi, Beáta
We present an empirical study on instructions found in historical cipher keys dating back to early modern times in Europe. The study reveals that instructions in historical cipher keys are prevalent, covering a wide range of themes related to the practical application of ciphers. These include general information about the structure or usage of the cipher key, as well as specific instructions on their application. Being a hitherto neglected genre, these texts provide insight into the practice of cryptographic operations.

An early French digit cipher: deciphering a letter from the King of France to the Duke of Nevers (1592)
(Tartu University Library, 2024) Desenclos, Camille; Lasry, George; Waldispühl, Michelle; Megyesi, Beáta
We deciphered a single letter written in 1592 by Henry IV, King of France, to Louis de Gonzague, Duke of Nevers, held in the Bibliothèque Nationale de France (BnF). The ciphertext mostly consists of contiguous digits, and demonstrates an early use of digit ciphers in 16th-century France. In this letter, Henri IV exposes some parts of his current military strategy against the Catholic League. After deciphering the letter, we were able to locate the original cipher table in another BnF manuscript, illustrating how codebreaking may assist historical research both to reconstruct the content of encrypted letters and to identify anonymous cipher tables.

Artificial neural network for hoax cryptogram identification
(Tartu University Library, 2024) Foxon, Floe; Waldispühl, Michelle; Megyesi, Beáta
Numerous putative cryptograms remain unsolved. Some, including the Dorabella cryptogram, have been suggestedas hoaxes, i.e., some sort of gibberish with no meaningful underlying plaintext.The statistical properties of a putative cryptogram may be modelled to determine whether the cryptogram groups moreclosely with real or with randomly generated plaintext. Ten thousand plaintexts from an English-language corpus, and ten thousand (pseudo-)randomly generated English-alphabet gibberish texts were studied through their statistical properties, including the alphabet length; the frequency, separation, and entropy of n-grams; the index of coincidence; Zipf’slaw, and mean associated contact counts. An artificial neural network (deep learning) model was fitted to these data, with a cross-validated mean accuracy of 99.8% (standard deviation: 0.1%). This model correctly predicted that arbitrary, out-of-sample simple substitution ciphers represented meaningful English plaintext (as opposed to gibberish) with probabilities close to 1; correctly predicted that arbitrary, out-of-sample gibberish texts were gibberish (as opposed to simple substitution ciphers) with probabilities close to 1; and assigned a probability of meaningful English plaintext of 0.9996 to the Dorabella cryptogram.

Bringing Cryptology into the Secondary Education Classroom
(Tartu University Library, 2024) Murphy, Catherine; Wootton, Aaron; Waldispühl, Michelle; Megyesi, Beáta
Cryptology is becoming increasingly commonplace in undergraduate mathematics curricula as a way to motivate abstract mathematics. However, it is still typically absent in secondary education (students aged 11 to 18). In the following, we discuss why we think it would be advantageous to bring cryptology, both historical and modern, to the secondary education classroom. Additionally, we discuss some of the barriers we perceive to doing so and suggest, in our opinion, how they might be overcome. We illustrate implementation with a specific example of a topic in cryptology that could be included in a secondary education classroom.

Can Artificial Intelligence solve the mysterious anagram from the church of the Poor Clares in Bratislava?
(Tartu University Library, 2024) Antal, Eugen; Zajac, Pavol; Waldispühl, Michelle; Megyesi, Beáta
A mysterious anagram was found in the Church of the Poor Clares in Bratislava, but as far as we know it has never been successfully solved. The anagram contains81 symbols, including specific diphthongsAE, CH, and GY. Unlike other anagramstypical of that age, the symbolsare not ordered alphabetically. We suspectthat a specific order of symbols is relatedto the original order of symbols in theplain text. Even with the suspected orderof letters, the number of possible plain textcandidates is too high to obtain the originaltext with standard methods. We examinealternative scoring methods based onmodern AI text similarity to improve thequality of the candidate plain text candidates.
