Goal:

After this course the students

• have a deep understanding of design principles of security protocols and security infrastructures.
• have knowledge of the basic security goals in cryptography and its relevance to practical use cases.
• understand, in which way well-known security protocols (TLS, PACE, EAC) achieve the security goals.
• understand the key topics of the wide-spread security infrastructure standards and apply them to practical tasks.
• are able to choose suitable protocols for a given use case.
• can evaluate the security properties of security protocols and infrastructures.
