Aim:
After completing this course the student should be able to make a reasonable assessment of given cryptographic systems and choose a good solution for situations where cryptographic techniques can help.
Knowledge is required about what basic types of algorithms that exist, what requirements each type must fulfill and how each type works in principle. For some algorithms and algorithm classes, like RSA, Feistel networks etc., also the exact structure must be known.
The student should master the basic principles of cryptanalysis to the extent of being able to systematically apply them to solve simple examples of historical algorithms.
The student is expected to be able to use the general algorithm requirements and algorithm knowledge to perform simple evaluations and point out weaknesses of algorithms and how they are used.
