Implementation and Didactical Visualization of the Chacha Cipher Family in Cryptool 2
Implementation and Didactical Visualization of the ChaCha Cipher Family in CrypTool 2 Bachelor’s Thesis Ramdip Gill Supervisor Priv.-Doz. Dr. Wolfgang Merkle Second Supervisor Prof. Dr. Frederik Armknecht Heidelberg, December 11, 2020 Faculty of Mathematics and Computer Science Heidelberg University ABSTRACT This thesis is about the implementation of the ChaCha plug-in in CrypTool 2. The thesis introduces the ChaCha cipher family, explains what the plug-in is capa- ble of, and gives insight into the development process of the plug-in. ChaCha is used in the Transport Layer Security protocol (TLS) since 2014 and so very relevant for applied modern cryptography. Because of the importance of ChaCha its internal design should be made more accessible to the broader public. This is the actual goal of the plug-in. The goal is achieved by focusing on an in-depth but easy to understand visualiza- tion of the encryption process. CrypTool 2 is the most popular e-learning platform in the field of cryptology, used in schools, universities, and companies. Incorporat- ing this plug-in into CrypTool 2 helps to reach a broad audience. iii ZUSAMMENFASSUNG Diese Bachelorarbeit befasst sich mit der Implementierung des ChaCha Plugins für CrypTool 2. Die Arbeit stellt die Familie der ChaCha-Chiffren vor; erklärt, wozu das Plugin in der Lage ist; und gibt Einblick in den Entwicklungsprozess des Plugins. ChaCha wird seit 2014 im Transport Layer Security-Protokoll (TLS) verwendet und ist daher für die angewandte moderne Kryptographie sehr relevant. Aufgrund der Bedeutung von ChaCha sollte sein internes Design der breiten Öffentlichkeit zu- gänglicher gemacht werden. -
By Jennifer M. Fogel a Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy
A MODERN FAMILY: THE PERFORMANCE OF “FAMILY” AND FAMILIALISM IN CONTEMPORARY TELEVISION SERIES by Jennifer M. Fogel A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Communication) in The University of Michigan 2012 Doctoral Committee: Associate Professor Amanda D. Lotz, Chair Professor Susan J. Douglas Professor Regina Morantz-Sanchez Associate Professor Bambi L. Haggins, Arizona State University © Jennifer M. Fogel 2012 ACKNOWLEDGEMENTS I owe my deepest gratitude to the members of my dissertation committee – Dr. Susan J. Douglas, Dr. Bambi L. Haggins, and Dr. Regina Morantz-Sanchez, who each contributed their time, expertise, encouragement, and comments throughout this entire process. These women who have mentored and guided me for a number of years have my utmost respect for the work they continue to contribute to our field. I owe my deepest gratitude to my advisor Dr. Amanda D. Lotz, who patiently refused to accept anything but my best work, motivated me to be a better teacher and academic, praised my successes, and will forever remain a friend and mentor. Without her constructive criticism, brainstorming sessions, and matching appreciation for good television, I would have been lost to the wolves of academia. One does not make a journey like this alone, and it would be remiss of me not to express my humble thanks to my parents and sister, without whom seven long and lonely years would not have passed by so quickly. They were both my inspiration and staunchest supporters. Without their tireless encouragement, laughter, and nurturing this dissertation would not have been possible. -

An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext
An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext By Isaac Quinn DuPont A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Faculty of Information University of Toronto © Copyright by Isaac Quinn DuPont 2017 ii An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext Isaac Quinn DuPont Doctor of Philosophy Faculty of Information University of Toronto 2017 Abstract Tis dissertation is an archeological study of cryptography. It questions the validity of thinking about cryptography in familiar, instrumentalist terms, and instead reveals the ways that cryptography can been understood as writing, media, and computation. In this dissertation, I ofer a critique of the prevailing views of cryptography by tracing a number of long overlooked themes in its history, including the development of artifcial languages, machine translation, media, code, notation, silence, and order. Using an archeological method, I detail historical conditions of possibility and the technical a priori of cryptography. Te conditions of possibility are explored in three parts, where I rhetorically rewrite the conventional terms of art, namely, plaintext, encryption, and ciphertext. I argue that plaintext has historically been understood as kind of inscription or form of writing, and has been associated with the development of artifcial languages, and used to analyze and investigate the natural world. I argue that the technical a priori of plaintext, encryption, and ciphertext is constitutive of the syntactic iii and semantic properties detailed in Nelson Goodman’s theory of notation, as described in his Languages of Art. I argue that encryption (and its reverse, decryption) are deterministic modes of transcription, which have historically been thought of as the medium between plaintext and ciphertext. -
