Security, lectures, Fall 2017

General information on this course can be found in the studiegids.

Information about the exercises can be found on a different page.

The first lecture will be on Thursday Sept. 7, 13:45, in CC4. The exercise courses start one week later, on Sept. 15, at 13:45, in HG00.303 and HG00.307.

Don't forget to register officially for this course, in Osiris; blackboard will only be used for emails announcements and marks.

For background information and further reading we refer to the book Everyday Cryptography by Keith Martin. A pdf is available in Blackboard. Another very good source of information is the book Security Engineering by Ross Anderson, that can be downloaded from the author's website.

Slides are being produced as the course proceeds:
