Side-Channel Attacks and Defenses

Hi, 

the exam is already next week (28.2.2023 10:00), so do not forget to register in LSF. The registration deadline ends today!

A few details regarding the exam:

• The exam takes place in person on February 28, 10:00 in room E2 2 (Günter-Hotz-Hörsaal).
• You need at least 26 points in the practical part to be admitted to the exam
• No lecture notes or any other materials are allowed during an exam
• The lecture-challenge system closes on 27.02.2023 23:59. Until then, you can collect bonus points for the exam. If you did not register with your student mail address, you have to write your username on the exam sheet to get the points!

Cheers,
Michael

Dear students,
unfortunately, we found out that some keys [0] from practical2 were incorrect.
Thus, the server tested against the wrong keys and we handed out the wrong keys for challenge3.

We've updated the keys on the server and in the upstream repo. Hence, you need to merge the upstream repo again [1]. We rerun the tests for exercise 2 and the changes result in some student solutions now achieving 5/5 correctly leaked keys on challenge2. So, luckily nobody lost points by this error.

We apologize kindly for the trouble caused by this.

[0]: the affected keys were one non-public key from challenge 2 and all keys (public and non-public) from challenge3.

[1]: The command for doing so is "git pull upstream master --allow-unrelated-histories"

Hey all,

on next Tuesday, 13th Dec at 2pm, we will offer a tutorial session discussing a few tips and tricks to reduce the noise in your environment when developing microarchitectural attacks. Especially for those of you that are struggling with imprecise measurements in Practical 1, this tutorial should be helpful.
