  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.

    Nyckelord :Passive OS Fingerprinting; Encrypted Traffic Identification; Automated Traffic Analysis; Machine Learning; Supervised Learning; Networks; Packet Classification; Security and Privacy;

    Sammanfattning : The increase in cybercrime and cyber-warfare has spurred the cat-and-mouse game of finding and attacking vulnerable devices on government or private company networks. The devices attacked are often forgotten computers that run operating systems with known exploits. LÄS MER

  7. 5. 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.
