Kryptologi, Enigma maskinen og RSA-kryptering

Abstract

This paper examines a few widely used methods of cryptology and takes a look at the German Enigma-machine’s influence on how the 2. World War evolved, especially concerning the Battle of the Atlantic. Throughout time, humans have had the need to communicate secretly. The most practical way of doing this is through cryptology. Due to this, there is an extremely large number of different algorithms to ensure the secureness of transferring information. Not until recently, there has been a method that is practically unbreakable, while also working in the real world. The method is called RSA-encryption, and is widely used all over the world by banks, websites, and basically anyone who wants to transfer information easily and securely. RSA-encryption is based on prime numbers and their unique properties, but the overall principle is the same as any other cryptological method. During the Second World War the Germans used a machine for encrypting and decrypting their messages. This machine was called Enigma, and played an important part in the war. In this paper there is a detailed description of how the Enigma worked and what the influence on the war was, when the Allies broke its code. [Læs mere…]

Den franske revolution og borgerskabets rolle 1789

Indledning

Den franske revolution fandt sted i årene 1789-1799 og opfattes som én af de vigtigste begivenheder i nyere tid. Ifølge oplysningstiden og den amerikanske uafhængighedskrig, blev tankerne om borgernes rettigheder for lighed og frihed sat i særligt fokus.

I denne opgave vil jeg belyse Den Franske Revolution og helt specifikt, hvordan borgerskabet spillede en helt central rolle i opgørelsen med middelalderens stændersamfund. Jeg vil lægge særlig vægt på min kilde om den franske forfatning, da den er et vigtigt omdrejningspunkt i revolutionen.

Mit mål for opgaven er at besvare min problemformulering ved at gå taksonomisk frem. Jeg vil først redegøre for samfundsopbygningen i det gamle regime og årsagerne til revolutionens udbrud. Dernæst vil jeg undersøge og beskrive revolutionens videre forløb med særligt fokus på borgerskabet og deraf perspektivere det til min kilde om forfatningen.

Til sidst vil jeg vurdere, om borgerskabet nåede sit endelige mål ved hjælp af forklaringer og fortolkninger af revolutionen og dens årsager. Min besvarelse af problemformuleringen er hovedsageligt skrevet på baggrund af bøgerne Den franske revolution bind 1 & 2 af Niels Høffding. [Læs mere…]

Aggression

Abstract

This study examines how aggression is portrayed in literature and how the psychological explanations of aggression have developed through time. The study starts out by giving an account of various psychological theories relevant in the analysis and interpretation of the books, such as the psychoanalysis of Freud, Behaviourism and social psychology. Thereafter there is an analysis and interpretation of three books from various periods in time: Robert L. Stevenson’s ‘The Strange Case of Dr Jekyll and Mr Hyde’ from 1886, Anthony Burgess’ ‘A Clockwork Orange’ from 1962 and J.G Ballard’s ‘Running Wild’ 1988. Lastly the study assesses how the books mirror their contemporary time. [Læs mere…]
