1. 1. Models, Keys, and Cryptanalysis: Evaluating historical statistical language models in cryptanalysis of homophonic substitution ciphers

   Kandidat-uppsats, Göteborgs universitet/Institutionen för filosofi, lingvistik och vetenskapsteori

   Författare :Filip Fornmark; [2023-01-19]
   Nyckelord :statistical language models; cryptanalysis; historical cryptology; homophonic substitution;

   Sammanfattning : This thesis presents an empirical study connected to historical cryptography and especially within the framework of the research project DECRYPT. One of the research questions in the DECRYPT project relates to the use of language models for automatic cryptanalysis. LÄS MER

3. 2. Evaluating and Fine-Tuning a Few-Shot Model for Transcription of Historical Ciphers

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Ingrid Eliasson; [2023]
   Nyckelord :historical ciphers; few-shot learning; automatic transcription;

   Sammanfattning : Thousands of historical ciphers, encrypted manuscripts, are stored in archives across Europe. Historical cryptology is the research field concerned with studying these manuscripts - combining the interest of humanistic fields with methods of cryptography and computational linguistics.

4. 3. The Influence of Language Models on Decryption of German Historical Ciphers

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Justyna Sikora; [2022]
   Nyckelord :historical cryptology; historical language models; historical ciphers;

   Sammanfattning : This thesis assesses the influence of language models on decryption of historical German ciphers. Previous research on language identification and cleartext detection indicates that it is beneficial to use historical language models (LM) while dealing with historical ciphers as they can outperform models trained on present-day data.

5. 4. Cleartext detection and language identification in ciphers

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Maria-Elena Gambardella; [2021]
   Nyckelord :historical cryptology; digital humanities;

   Sammanfattning : In historical cryptology, cleartext represents text written in a known language ina cipher (a hand-written manuscript aiming at hiding the content of a message).Cleartext can give us an historical interpretation and contextualisation of themanuscript and could help researchers in cryptanalysis, but to these days thereis still no research on how to automatically detect cleartext and identifying itslanguage.
