Mobile Security

The exam tomorrow will take place at the originally planned time: 10:00 – 12:00

Same as for the test exam, the exam sheet and Word template for answers will be published on Moodle a few minutes before the beginning of the exam. To download the sheet and template, you need to first confirm your attendance in the "Attendance check" (which will also be published a few minutes before the beginning of the exam). To submit your solution, save your Word file with your answers as PDF and upload it to Moodle as your submission to the Online Endterm Exam.

For announcements from our side, we use the "Exam announcement" channel in Teams.

For questions by you during the exam (e.g., if an exam question is unclear to you), please use the meeting in the "Exams questions" channel in Teams.

Dear all, following the recommendation by the university we will try to set the exams for this course up as "online digital exams" (see here). Since this is likely a new procedure for most of you (and us), we will have a test online exam this Friday at 09:45 – 10:15 just before the regular call with Teams. If you like to participate in this test exam and provide feedback on this process, please contact me and send me your Moodle user ID (this should be your regular UdS account name, e.g., for LSF/HISPOS) and I will enroll you in the Moodle course for Mobile Security. Please also check that you can actually log in to Moodle and can access the course after being enrolled.

Regarding the procedure as advised by the university:

• the exam sheet will be published at the exam starting time via Moodle and you have the regular 120 minutes to work on it (30 minutes for the test exam)
• we will provide a Word file with the same structure as the exam sheet and you must write your answers into this Word file (e.g., using LibreOffice, Microsoft Office, etc.)
• save your exam solution as a PDF and upload the PDF within the allotted time to Moodle (there is a short grace period after the 120 minutes to upload your sheet)
• the exam will in this case be open book, i.e., there is no restriction on the auxiliary materials that you use (e.g., lecture slides, etc)
• for questions during the exam, we will offer the Moodle chat and an extra "Exams" channel in Teams
• attempted deception (e.g., copying answers from another participant) that we detect in the answers will have the same consequences as attempts to cheating during a closed-book exam

Thus, to participate in the online exams you need:

• To be admitted to attend the exam (i.e., have the necessary points from the exercises)
• To be registered for the exam in the LSF/HISPOS
• Access to the UdS moodle and have been enrolled in the Mobile Security course on Moodle
• An editor for Word files that can save as PDF
• Stable enough Internet connection to retrieve the exam sheet & Word template and upload your solution to Moodle

Unfortunately, this year we are unable to host the course project since the necessary computational resources had to be bound to some urgent research projects. For those of you interested in extending AOSP's security architecture (and being able to build AOSP on their own machines), we will release the instructions, however, this is not a graded exercise and merely for self-study if interested.

To compensate, we made a change to exercise 5 by increasing it to 40 points (from originally 20 points) and we adjusted the threshold for getting admission to the exam to 160 points.

We would like to let you know that we have published exercise 3. However, since we had to make slight changes to one specific task, we had to upload an updated version of the exercise. In case you already downloaded the old exercise sheet and apps, we kindly ask you to download them again from the CMS to get the latest changes. Thank you.
