Communication Network Security (MINF-KT-CNS)

This module will be in English!

Ziele und Inhalte

This is a Master Degree module to introduce cryptographic mechanisms, services and attacks in securing contemporary communications networks. After completion of this module students will gain:
•    advanced knowledge and experience in cryptographic mechanisms and services and their theoretical background,
•    state of the art security problems and solutions for communications networks,
•    security needs of future heteregenous communications networks and Internet.

Lecture supported by the project will enable students to analyse and develop a deep understanding of security needs of contemporary communications networks. Students will be able to follow state of the art research results published in high rank conferances and journals. Module will cover the topics which are not only in the interest of research institutes and academies but also industries.

The lecture part will cover (i) cryptography basics such as symmetric cryptography, asymmetric cryptography and their theoretical backgrounds, (ii) security protocols and applications from communication networks, and (iii) advanced cryptographic mechanisms which are used in malicious cryptography, data privacy, trust management, key management and ID management.
1.    Introduction (Attacks, Services, Mechanisms),
2.    Classical cryptography, Cryptanalysis and Theoretical Foundations
3.    Block Ciphers: DES, 3DES, AES and Modes
4.    Stream Ciphers, PRNG, Key Management
5.    Symmetric Cryptography Applications in Communications Networks
6.    Asymmetric Cryptography: RSA, PKC, Number Theory
7.    Diffie-Hellman, ElGamal, Elliptic Curves, Digital Signature Standard
8.    Assymmetric Cryptography Applications in Communications Networks
9.    Key Management and Secret Sharing
10.    ID Management and Authentication Schemes
11.    Topics in Malicious Cryptography, Privacy or Trust Management

For the project part, students will be divided into groups. Each group will select a recent communications network security problem provided by the lecturer. The problems will be carefully picked so that:
•    They can be solved by application of the materials covered in the lecture.
•    The problems are recent so that students will earn an expertise which will also be useful for the rest of their education and academic / professional lives.
