Status Update: Grades still CANNOT be entered in LSF

Written on 04.10.18 by Stefan Nürnberger

Unfortunately the situation that grades cannot be entered in LSF is still true as of today. They wanted to fix the issue more than 3 weeks ago but apparently I cannot not enter your grades in LSF. I'm sorry about that but it's not my fault. The HIZ is working on that matter and I try to urge them… Read more

Small fix for current exercise

Office hour room change and small reminder

Due to the unavailability of our usual room for the office hour, it takes place in room 2.22 today.

Due to the unavailability of our usual room for the office hour, it takes place in room 2.22 today.

Also small reminder that you may not use command line tools to measure the integrity of your files in the current task.

You may also not use your C code as a wrapper to the already existing programs (like for example the preexisting flushcontext program in the TSS).

This approach will not yield any points. You may of course look at the source code of such programs and implement your task similarly.

Have fun!

Even though you have three weeks to complete the tasks, the first task is tricky. As always you can ask questions via E-Mail, the forum or in the office hours. Note that this office hour on thursday we will discuss the last exercise sheet in the Lecture hall, but we are also happy to answer questions concerning the actual exercise sheet.

If you want to try out your ESP's WLAN configuration, you can do so in the students working room in the second floor. We installed a router for you.

We expect you to own a functional micro USB cable for the new hardware. If neither member of your team does have such a cable, please write a message to the tutors. We do not have many of these, so please only take a cable from us if there is no other way for you to get one.

Fix concerning current sheet exercise 2

Written on 28.05.18 by Simeon Hoffmann

It has brought to our attention that there was a small mistake in the provided code for exercise 2. This is now fixed on the hardware and the updated sheet is online. You may want to check if your attack still works, but if you implemented a correct bufferoverflow as stated in the exercise, nonthing should change.

Information for exerise 1: You need to be in the same /24 subnet ip range as the arduino, hence any 192.168.1.x ip should do.

Also, make sure that the ID of the CAN frame you send to the arduino is exactly 3 characters long.

There was a small but decisive fix in the exercise. You may want to redownload the exercise.

Exercise 2 points are online, Office hour changes and building access

Written on 16.05.18 by Simeon Hoffmann

The points for exercise 2 are online now.

The overall schedule of the course changes a little bit: instead of office hour every week, we will offer a tutorial in the week after you submitted an exercise in the office hour slot. In this tutorial, we will discuss the solution of the most recent exercise sheet. This tutorial takes place in the lecture hall. This new schedule starts immediately, hence there will be a tutorial tomorrow at 4 pm in the lecture hall.

As you might need building access for future exercises again, please send your card id (the number in the top left of your UDS card) in a mail to one of the tutors if you do not have building access already. Make sure that it is a 17-digit number, as the older cards (less digits) are not supported for granting building access. If you have such an old card, you can change it to the newer model at campus center. It should be free of charge if you mention that you need access to the CISPA building.

Exercise 2 and lecture next week

Written on 11.05.18 by Simeon Hoffmann

Exercise 2:

We acknowledge that the second task from the current exercise is out of scope for this course (too hard). Hence we change the evaluation of this exercise: you will get up to full points for this exercise if you can present an approach that will lead you to the result and that shows that you understood the problem. You DO NOT need the secret to receive full points for this exercise. However if you managed to extract the secret and can present how you did it, you will be awarded 5 bonus points.

Lecture next week:
There will be no lecture next week and thus no new exercise sheet. Please note that the current deadline IS NOT extended.

Next week on monday (a holiday), there will be a video upload with a new lecture and a new exercise sheet. You have the full two weeks to work on this exercise sheet.

Replacement office hour

Written on 10.05.18 (last change on 11.05.18) by Simeon Hoffmann

As there seem to be a lot of issues concerning the current exercise sheet and today is a holiday, there will be a replacement office hour tomorrow at 4 pm. It will take place in the usual room, room 2.21 in the CISPA building.

Exercise 2
