Thesis projects and finished theses with the cryptology and data security research research group at the University of Bern and in the Swiss Joint Master in Computer Science.

See also courses

Many projects address theory and practice of cryptology and data security; some are purely theoretic but very few are only of practical nature.

Available projects for B.Sc. and M.Sc. theses

Further projects in the research domain of the group are possible. If you would like to suggest a topic for a thesis project, please contact a team member to discuss your idea.

These projects are intended for computer-science students at the University of Bern and those enrolled in the Swiss Joint Master of Science in Computer Science. We do not offer any internships.

Instructions and templates for theses

Once you have agreed with your supervisor on a topic and on a start- and end-date, fill in the corresponding form and complete the respective procedure:

Presentation

Every thesis must be presented near the completion or at the end of the project. Usually this occurs during the semester, within the regular seminar organized by the Cryptology and Data Security group. BSc students must also attend the seminar as a regular participant and get credit for it. The seminar’s title may vary; see the course page for details. You should agree with your supervisor in the initial stage of the thesis on where and when to present your work.

Software

For archiving software and thesis report, log in once to the INF gitlab server with your Campus Account (small login box at the bottom). This creates your user representation inside the server. Then ask your supervisor to create a repository for the project under the group crypto-students according to the pattern:

https://gitlab.inf.unibe.ch/crypto-students/2019.bsc.firstname.lastname
https://gitlab.inf.unibe.ch/crypto-students/2020.msc.firstname.lastname 

Thesis template

For a BSc thesis a sample template is available on the Cryptography and Data Security group website.

For a Msc thesis, the sample template is available on JMCS website.

Together with the original thesis submission, a signed declaration (“Erklärung”) must be included, in which the candidate confirms that she/he personally authored the work.

Writing

Theses are written in English. Refer to a manual of style for guidance on writing scientific texts.

Graduation

After finishing the thesis, follow the steps to graduate.
