Welcome to TEK4500 Introduction to Cryptography Fall 2023!
This is the main page for the course. Here you will find course information and any announcements I make for the course, as well as links to lecture slides, recordings, problem sets, and any other material. Please check it regularly. There is also a Canvas page for the course, but we will only use it to publish solutions to home work problems, as well as discussions for the course.
The grades for the exam are now published on StudentWeb.
Thank you all for attending the course.
The exam and a suggested solution is now available on Canvas ("Files -> Previous exams"). Please do not distribute further.
Happy holidays!
I'll be available in Lille Auditorium from 13:00-14:00 on Wednesday 13 to answer questions regarding the exam. You can of course also send me emails with questions if you want too.
I'll do a course recap lecture tomorrow (December 6). If you have any topic you want me to discuss in particular, please let me know.
This is a reminder for today's (November 29) guest lecture by Martin Strand from FFI, on the algorithm Kyber, which is soon to replace (or complement) the Diffie-Hellman algorithm in order to protect against quantum computers.
Martin is a great presenter and I highly recommend everyone to attend!
Old exams are now available on Canvas ("Files" -> "Previous exams").
Note I: the exam in 2020 was an open-book take-home exam, and also gave the students 30 minutes extra during the exam (4.5 hours total). This is unlike this year's exam, which is a closed-book on-site exam (4 hours total).
Note II: Before 2020 the course had a different lecturer and used a different textbook. Hence, there might be slight differences in what was emphasized. These exams are put in the folder "older".
Exam
- If you did not pass the midterm or have not yet submitted two homework problem sets, but still want to take the exam: come see me (or send me an email) and we'll figure it out!
- I'll make old exams available on Canvas soon.
Remaining lectures
- November 22: regular lecture (quantum computers)
- November 29: guest lecture!
- Martin Strand (researcher at FFI) will come and talk about post-quantum algorithms
- December 6: course recap lecture + ask-me-anything session
- If you have any specific topic you want me to repeat/treat in more detail, please let me know in advance.
Unfortunately, I forgot to press the record for the second half of today's lecture (on Group theory/Diffie-Hellman). Thus, I have instead uploaded the recording of the second part of the same lecture from last year, which should mostly cover the same material (modulo yearly jokes and changes).
While you are free to use whatever tool you like to write your homework assignments, I highly recommend to use LaTex. There's a template file on Canvas that's ease to use and contains some useful commands for this course. Also, you don't have to install anything to use LaTex: simply use Overleaf!
Due to a scheduling conflict the group recitation hours needs to change. The new hours are: 11:15-12:00, starting from next week (September 13). The room will (most likely) still be Black Box.
Unfortunately, today's recording of the lecture did not include any audio so there is no point in publishing it. For those who did not attend today's lecture it's possible to watch the first lecture from last year here. It basically covers the same material.
I apologize for this inconvenience. Hopefully things should be sorted by next week when start using a different lecture room (Smalltalk).
First lecture: Wednesday 12:15-15:00, August 30, in Store auditorium , Kristen Nygaards hus.
All other lectures: Wednesdays 12:15-14:00 in Smalltalk, Ole Johan Dahls hus. Note that the first lecture is in a different room!
Video recordings of the lectures (voice + screen capture) will be available on Canvas after the lectures (registered students only).
Recitation: Wednesdays 14:15-15:00 in ...
