Exam project: Principles of modern block encryption (SSO)

On your final year in Danish high school, you are required to write a project on one of your Majors. I chose to write my project on mathematics, focussing on the principles of block encryption in the Rijndael algorithm (used in AES).

The resulting paper has two sections: the first section explains the principles metaphorically in Layman’s terms. The second part, however, includes all the mathematical solutions and to this date I don’t know anyone except my math teacher who has read this part.
