TEK4500 – Introduction to Cryptography
Classical systems, information theory, mathematical background material, symmetrical crypto systems, block ciphers, stream ciphers, DES, Advanced Encryption Algorithm (AES), hash functions and message authenticaion (MAC), asymmetric cryptosystems, RSA and El Gamal, digital signatures, elliptic curves, provable security.
After completing this course, you will:
- be able to descibe central aspects of symmetric and asymmetric cryptography
- have knowledge and understanding of how cryptographic techniques are used to establish security in modern information- and communication systems.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.
Formal prerequisite knowledge
Recommended previous knowledge
The course assumes knowledge in discrete mathematics equivalent to MAT1030 - Discrete mathematics (MAT008),(MA-IN 118). Useful background is also MAT1120 - Linear Algebra (MA131),(MA215) and INF3210 - Information design (IN210).
- 10 credits overlap with UNIK4220 – Introduction to Cryptography (continued)
- 10 credits overlap with UNIK9220 – Innføring i kryptografi (discontinued)
- 8 credits overlap with UNIKI-IKRY
2 hours of lectures and 1 hour of problem solving sessions per week.
Compulsory assignments have to be handed in and approved. In case of a large number of students, written exam may be an alternative.
Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.
Explanations and appeals
Resit an examination
Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.
Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
Withdrawal from an examination
It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.
Exam attempts in this course is counted together with UNIK4220 – Introduction to Cryptography (continued).
The course was previously called UNIK4220 – Introduction to Cryptography (continued).
