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 Transcription of Ciphers with Few-Shot Learning

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

   Författare :Nikolina Milioni; [2022]
   Nyckelord :Ciphers; Automatic Transcription; Decrypt project; Few-shot learning;

   Sammanfattning : Ciphers are encrypted documents created to hide their content from those who were not the receivers of the message. Different types of symbols, such as zodiac signs, alchemical symbols, alphabet letters or digits are exploited to compose the encrypted text which needs to be decrypted to gain access to the content of the documents.

4. 3. Lost in Transcription : Evaluating Clustering and Few-Shot learningfor transcription of historical ciphers

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

   Författare :Giacomo Magnifico; [2021]
   Nyckelord :Image Recognition; Handwritten Text Recognition; HTR; Deep-learning; K-mean clustering; NN; Neural Network; Few-Shot;

   Sammanfattning : Where there has been a steady development of Optical Character Recognition (OCR) techniques for printed documents, the instruments that provide good quality for hand-written manuscripts by Hand-written Text Recognition  methods (HTR) and transcriptions are still some steps behind. With the main focus on historical ciphers (i.e. LÄS MER

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.

7. 5. Electromagnetic analysis of AES-256 on Xilinx Artix-7

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Oskar Westman; [2018]
   Nyckelord :Electromagnetic side-channel attack; AES-256; Artix-7; FPGA; Differential analysis; Simple analysis.; Technology and Engineering;

   Sammanfattning : In this project, an electromagnetic side-channel attack has been made by exploiting the information leakage from a field programmable gate array (FPGA) and an implemented advanced encryption standard with a 256-bit key (AES-256). The FPGA-board was a Nexys-4 from Digilent with Artix-7 FPGA. The attack was partially successful. LÄS MER
