    ”Fullständigt otillförlitlig, men absolut oumbärlig”. En historiografisk undersökning av projektet Svensk Stad
    (Acta Universitatis Gothoburgensis, 2018-03-19) Dahlgren, Anders
    This dissertation is a historiographical study of the research project Svensk stad (Swedish Town). The project, lead by the professor in Art History Gregor Paulsson (1889-1977), included about 20 members and was conducted between 1940 and 1953. The interdisciplinary studies ot the Swedish towns of the 19th and early 20th century combined methods and perspectives from art history, sociology, cultural geography and european ethnology. The dissertation has two main lines of inquiry: interpretation and mapping. The interpretation of Svensk stad is related to a a hermeneutic tradition (Hans-Georg Gadamer) and psychoanlytic theory (Sarah Dillon) and aims at investigating the theoretical and methodological perspectives that were integrated in the project. The mapping, uses perspectives and methods from the field of sociology of science (Bruno Latour, Andrew Pickering, Susan Leigh Star och James Griesemer). A third line of inquiry of the dissertation combines the two main lines and analyses the project’s paths to knowledge using concepts from visual studies. The primary empirical material consists of the published work Svensk stad, and preserved archive material from the project.

    IPsec, the Future of Network Security?
    (2000) Jönsson, Oskar; Dahlgren, Anders; Göteborgs universitet/Institutionen för informatik
    This master thesis deals with Internet security in general and IPsec in particular. Traffic and transactions over the Internet are risky, and credit card numbers are easily stolen and abused. IPsec has been developed to ensure security and integrity and we discuss how IPsec works and where in the computer network it resides. In order to come up with any conclusions and results, we did a literature research of the Internet Engineering Task Force's (IETF) Request For Comments (RFC) documents on the Internet. The few books available are also built upon the RFCs. The study found that IPsec will provide security for all kinds of computer traffic without, or with little, human interaction. IPsec can replace current application security techniques like PGP etc. Since IPsec is built in a modular way it is future proof and it is easy to add new cryptographic methods when such are developed and proven more secure.
