### CS-E4320 - Cryptography and Data Security, 12.09.2016-08.12.2016

Omfattning: 5

Tidtabel: 12.09.2016 - 08.12.2016

Undervisningsperiod (är i kraft 01.08.2018-31.07.2020):

I - II (Autumn)

Lärandemål (är i kraft 01.08.2018-31.07.2020):

Having completed the course, you understand the security that commonly used cryptographic primitives provide as well as their limits. You are able to judge whether a cryptographic building block is suitable for use in a particular application, and you can assess security models for applications critically. You can construct reductions between cryptographic primitives and recognize whether small modifications to a cryptographic primitive compromise their security.

Innehåll (är i kraft 01.08.2018-31.07.2020):

We introduce cryptographic security models and concepts and understand the relations between them. We then apply the learnt concepts and techniques to real-world problems. In particular, we cover:

• One-way functions
• Pseudorandomness
• Pseudorandom generators
• Pseudorandom functions
• symmetric encryption
• asymmetric encryption
• message authentication codes
• signature schemes
• secure channels
• recent attacks on real-life protocols such as TLS, IPsec,...
