Tutor:

Filip Bělohlávek, Jaromír Hrad, Ivan Pravda, Tomáš Vaněk

Supervisor:

Department of Telecommunications Engineering

Synopsis:

The Information Security course provides a complete source of information on the field of security of information systems and information technologies. The most of information in today society is created, transferred, stored in electronic form so information security is very important part of it. Technical background for information security is provided by cryptology.

Requirements:

1. Modular arithmetics and algebra, basic statistics

2. ISO/OSI and TCP/IP network models, basic knowledge of computer networks principles

3. Programming in high-level languages (Java,C#, C/C++, Python) is an advantage

Syllabus of lectures:

1.Introduction to cryptology, historical overview

2.Block ciphers

3.Block ciphers modes of operation

4.Stream ciphers

5.Public key cryptosystems

6.Hash functions

7.Biometrics, Tokens, Passwords

8. Authentication and Authorization protocols

9.Virtual Private Networks

10.Cryptographic protocols - SSL / TLS, DTLS, SSH

11.X.509 certificate, certificate authority, Public Key Infrastructure

12.E-mail communication security - S / MIME, PGP

13.Electronic signature, electronic identity

14.Security in mobile networks

Syllabus of tutorials:

1.Introduction, passing conditions, health and safety regulations

2.Cryptanalysis of monoalplhabetic substitutions

3.Cryptanalysis of polyalphabetic substitutions

4.Cryptanalysis of transposition ciphers
