Homework & course rules
We will give out three sets of questions during the semester such that each set of questions is focused on the corresponding group of topics that is covered in the lectures. The homework tasks will be made public when we start to teach the corresponding topics. Three sets of homework tasks can give up to 45 points.
First homework covers the following topics: data protection, symmetric encryption, smart devices, privacy and anonymity. Second homework covers public key cryptography, HTTPS, end-to-end encryption, smart cards, e-voting, blockchain and payment systems. Third homework is mostly about authentication and attacks.
- Aggregated results
- The detailed results of the tests can be seen from Moodle.
- You can see your pseudonym for the information security course by logging in to courses.cs.ut.ee and visiting your profile. You can find your profile from the button that is located in the top right corner of the page.
There is a penalty for late submissions, which increases by each day being late. More information can be found from the section about submission policy.
After each lecture, there will be a small test to check if the most important ideas or facts were understood. The tests will give up to 5 points during the whole semester and a single test will give between 0.5 to 1 points.
The students have one attempt per test and the time limit is 15 minutes. Once the test is opened the timer starts and in 15 minutes the test is closed. Thus, we recommend to first attend the lecture and then read the lecture materials before taking the test. There are 5-10 questions in one test and the average completion time of a test is around 2-3 minutes in case the student has prepared.
The tests must be completed in Moodle (https://moodle.ut.ee) in ten days. Exact deadlines can be found from Moodle and the timezone of the deadline is GMT+2.
It is not possible to retake the Moodle tests as ten days should give enough time to plan your time. As an exception it is possible to retake the test in case of a medical emergency but for that a written proof by the doctor or hospital is needed.
In addition to the homework tasks each student should write one essay. The essay can give up to ten points and we have the option to grant up to 2.5 bonus points for exceptionally good essays. In case an essay is not submitted then it will not be possible to get an A. We do not give replacement tasks instead of the essay, which means that the student will have to collect the necessary 40 points in order to attend the exam.
Some example topics for the essays are posted below. We encourage students to propose their own topics! If you are not sure if your own topic is relevant then we can approve it before you start to write.
Each student has to write one essay during the semester. However, different topics have different deadlines as shown below. For example, if a student wants to write on a topic belonging to the first group (privacy, anonymity, encryption), he or she will have to submit it by October x-th. After this deadline these topics are no longer available.
- First group: privacy, anonymity, encryption (deadline: 18th of October)

- The essay should have the following structure:
- introduction - the aim is to get the attention of the reader, give background information and to state the problem
- content - claims / opinion, discussion, counter examples, the viewpoint of the opposing side, references to facts to back up the claims

Homework solutions and essays have to be submitted before the midnight of the deadline. The deadline is fixed to be in the time zone GMT+2. There is a penalty for late submissions, each extra day will lower the maximum result by 10%.
- 1 day late - homework result is multiplied by 0.9
- 2 days late - homework result is multiplied by 0.8
- 3 days late - homework result is multiplied by 0.7
If the homework submission is done more than nine days after the deadline then the solution will automatically get 0 points.
The lecturer should be informed as early as possible if the submission will be late due to a medical reason or due to an important upcoming event. If there is a valid reason for not being able to submit the homework then in agreement with the lecturer it might be possible to get an extension or an alternate task. This only applies when the lecturer is informed before the deadline (at least two days in advance, except in the case of a medical emergency).
The same policy applies for essays.
When a solution contains text from other authors then citation has to be used. This applies also when the information is copied from the course web page, although we strongly suggest to avoid copying text in homework solutions.
In case you are using someone else's ideas, facts or information, then a reference should be added (e.g., as a footnote). A reference is not required if the fact or information is common knowledge. In case important facts or information is provided without providing references then the task can be graded with 0 points.
Missing citation is considered as plagiarism and this results in the homework being graded with 0 points. In addition, such cases will be handled according to the study regulations (chapter IX.10. Academic fraud and improper behaviour) and the case is given to the vice dean.
205. If the student has committed academic fraud or otherwise behaved in an improper manner, the vice dean for academic affairs is required to [effective as of 4 September 2017] 205.1. reprimand the student, or 205.2. make a proposal to the vice rector for academic affairs for the student to be deleted from the matriculation register.
It is not allowed to submit a solution that was created by a third party. It is not allowed to use a solution created by another student. In case a copied solution is found all involved students will get 0 points. However, it is allowed to discuss the problems in the homework tasks with other students but the solutions have to be written independently. In this case, the names of the students involved in the discussion have to be mentioned in the solution. If this is not done or even part of the solution is copied then we consider it to be a case of plagiarism.
In addition, it is not allowed to show the solutions of written homework to other students while they have not submitted their final version of the same homework. In case this rule is violated such that it leads to a plagiarism case then both students are held responsible.
