Default Schedule

There was a little mess with room booking which we finally solved. The initial announcement for FLUX is outdated! The lecture will take place in Auditorium 12.
Dates and time: Location:
Tuesday, 10:45 - 12:30 AUD.12 FLUX 1.05, FLUX 1.08
Thursday, 13:45 - 15:30 AUD.12 FLUX 1.08, FLUX 1.10
Last lecture on Thursday, January 12th.

Lecture Videos

As we stopped tele-lecturing this year, the lectures are recorded. This has the advantage that also students that got conflicting lectures can follow the class. The videos should be online the day after the lecture. You can find the videos at the TU/e Mediasite (videocollege.tue.nl) under TU/e lectures → (2) Computer Science → 2DMI10 (2016-2017).


At the end of this course:


This course deals with modern applications of cryptography. Topics covered are These topics will be explained and failure cases and popular attacks will be pointed out. Depending on time and up to date developments the course might also cover private information retrieval, proofs of storage, quantum cryptography, post-quantum cryptography, and a 'bug of the week' section.


You have to write two papers, one in mid-term and one in the exam period. You will be asked to study some literature or a standard document, and report on that in written form. The first one will be on PKI, the second one on one of the other topics. In both cases there will be a list of topics from which you can choose.
The first paper has weight 1/3, the second one has weight 2/3.
All papers must be submitted encrypted and signed by email.



Here you find for each lecture a note on what has been treated, the slides, and further literature for some topics.
