| Learning Outcomes |
Competences |
| Students are able to understand, apply, analyze, and assess the most important cryptographic concepts, algorithms, and protocols to assure confidentiality, integrity, authenticity, and non-repudiation in the secure transmission and storage of data.
|

| Skills |
Knowledge |
Students are able to (all skills on K2 to K5):
- assure confidentiality (C) in secure communication using symmetric block ciphers
- assure confidentiality (C) using symmetric stream ciphers
- assure confidentiality (C) using asymmetric cryptosystems
- assure integrity (I) using cryptographic hash functions
- assure authenticity (A) and non-repudiation (N) using digital signatures
- provide CIAN assurances in constrained environments and settings
- provide CIAN assurances in an efficient and integrated manner using cryptographic protocols
- understand the implications of large scale quantum computers on the security of existing cryptographic standards and know how to assure CIAN using post-quantum algorithms
