Information and communication systems security

Aspects of security (authentication, privacy, confidentiality, non-repudiation, accessibility). Protection of communication and information systems (security policy, threats, authentication, authorization, firewalls, anti-virus protection). Stream chippers. Symmetric key encryption (DES, IDEA, AES). Asymmetric key encryption (exponential key exchange, RSA, elliptic curves). Hash functions (MD5, SH1). Digital signature. Key management (certificates, authentication, public key infrastructure). Cryptanalysis.

To understand the basic principles of data protection during their transfer and storage. To understand security in data access.  To understand the threats and different ways to secure information and communication systems.

Lectures and lab work. In lectures the students gain theoretical background and in lab they gain some practical experience. Part of the pedagogical process will be carried out with the help of ICT technologies and the opportunities they offer.
