Please let me know if it grades/points are not visible. If you would like to have an exam inspection, please let me know until Sunday night. I will then scan the respective exams and send them to you on Monday. I will also release the example solution for the exam until then. As a reminder, there is no re-exam offered in this class. I plan to finalize the grades and submit to LSF after the exam inspection. Please contact me if you need a Schein or similar. Regards, Nils |
Lab 6 process logic can get stuckWritten on 27.07.23 (last change on 28.07.23) by Nils Ole Tippenhauer Dear students, For lab6, the process can get stuck due to a bug in the PLC1 logic where P101 is never turned on. If you experience this issue, we recommend changing in `PLC1.py` the line 93 from ` if fit201 <= FIT_201_THRESH or lit301 >= LIT_301_M['H']:` to ` if lit301 >=… Read more Dear students, For lab6, the process can get stuck due to a bug in the PLC1 logic where P101 is never turned on. If you experience this issue, we recommend changing in `PLC1.py` the line 93 from ` if fit201 <= FIT_201_THRESH or lit301 >= LIT_301_M['H']:` to ` if lit301 >= LIT_301_M['H']:`. This should solve the issue (at least enough to demonstrate your attack). Please let me know if you run into other issues. \edit: someone noted that removing this dependency on FIT201 will make it difficult to meet the alternative goal. To simplify things, please feel free to modify the logic in PLC1 for the alternative goal part of the exercise to introduce other use of that variable, a different threshold for the original logic, or something similar. Just make sure to comment on this in your submission. Cheers, Nils |

Example GPS spoofing files for Ex3Written on 09.06.23 by Nils Ole Tippenhauer Dear students, I uploaded a .zip with (optional) help for Ex3: it contains two modified source files for Ardupilot to manipulate the computed GPS location. Feel free to use those files as example attack to detect in Ex3 in case you were unable to find other attacks in Ex2. Please let us know if… Read more Dear students, I uploaded a .zip with (optional) help for Ex3: it contains two modified source files for Ardupilot to manipulate the computed GPS location.

Physical-Layer Security
The lecture will take place every Friday from 12.15-13.45pm, starting April 14. It will be taught by Nils Ole Tippenhauer. Roughly the first half will focus on physical-layer wireless security, and the second half will focus on Cyber-Physical Systems/ Industrial Control Systems security. We currently plan to have a mix of interactive lectures via Zoom, and prepared videos. In addition, there will be practical exercises using Linux w/ GNUradio and other tools.
This lecture is an advanced lecture in Physical-Layer Security. Previous knowledge from CySec1 and CySec2, or Security is recommended. While the lecture will touch physical-layer concepts such as (wireless) signals, no background in that area is assumed. The lecture will cover thee main topic areas: attacks (and countermeasures) that leverage physical channels (e.g., side-channel attacks), attacks (and countermeasures) involving wireless communications (e.g., jamming, manipulation, and forwarding), and security for cyber-physical systems (such as industrial control systems).
The lecture will be complemented by 6 exercises (details TBD). Due to related effort, this course can only accommodate up to 50 students.
There will be a final written examination with no second backup slot. The exam date is 8. September 2023 at 10am in the CISPA Bernd Therre lecture hall.
