Content and learning outcomes
Course contents
Classical encryption methods. What is meant by secure encryption? Background in information theory, entropy. Symmetric encryption algorithms, for example the Advanced Encryption Standard (AES). Public-key cryptosystems for encryption and digital signatures, e.g., RSA, ElGamal, and Schnorr signatures. Cryptographically secure hash functions in theory and practice (SHA). Properties and examples of pseudo random number generators. Connections between complexity theory and cryptography.
Intended learning outcomes
After a completed course, the student should be able to
- discuss the following basic concepts in cryptography:
symmetric and asymmetric encryption, digital signatures, cryptographic hash functions and strong pseudorandom generators and to give examples of instantiations of each concept - conduct simple analyses of cryptographic constructions such as cryptosystems and cryptographic protocols
- read analyses performed by others of cryptographic constructions such as cryptosystems and cryptographic protocols and decide if the given analysis can be trusted
- read and understand technical articles in cryptography.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
A, B, C, D, E, FX, F
Examination
- ÖVN1 - Exercise, 7,5 hp, betygsskala: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Written exercises (OVN1; 7,5 university credits).
Opportunity to complete the requirements via supplementary examination
No information inserted
Opportunity to raise an approved grade via renewed examination
In this course there is no opportunity to raise an already approved grade.
Examiner
Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Supplementary information
The course is held in English if the students wish so.
You cannot count both DD2448 and DD2449 in your exam, since DD2448 has replaced DD2449.
