Fundamentals and applications of cryptography. Cryptography as a mathematical discipline: reductions, constructive cryptography paradigm, security proofs. The discussed primitives include cryptographic functions, pseudo-randomness, symmetric encryption and authentication, public-key encryption, key agreement, and digital signature schemes. Selected cryptanalytic techniques.
Objective
The goals are: (1) understand the basic theoretical concepts and scientific thinking in cryptography; (2) understand and apply some core cryptographic techniques and security proof methods; (3) be prepared and motivated to access the scientific literature and attend specialized courses in cryptography.
Content
See course description.
Lecture notes
yes.
Prerequisites / Notice
Familiarity with the basic cryptographic concepts as treated for example in the course "Information Security" is required but can in principle also be acquired in parallel to attending the course.
Performance assessment
Performance assessment information (valid until the course unit is held again)
The performance assessment is only offered in the session after the course unit. Repetition only possible after re-enrolling.
Mode of examination
written 120 minutes
Additional information on mode of examination
There will be one written intermediate exam ("midterm") during the semester. The grade achieved in the midterm influences the final grade if this influence is beneficial: The final grade is the maximum of (1) the grade achieved in the final session exam and (2) the weighted average of the grades achieved in the midterm (25%) and in the final session exam (75%). A bonus is not transferable to a future repetition of the final exam.
Written aids
None
This information can be updated until the beginning of the semester; information on the examination timetable is binding.
