Learning outcomes
|
The aim of the course is to inform students about the practical security implementation of electronic information. The subject offers basic information about methods of realisation of information system risk analysis including possible approaches to information evaluation, choosing adequate safeguards to secure confidentiality, integrity and availability of important information. Attention is focused on the use of cryptographic methods (hash functions, symmetric and asymmetric cryptosystems, digital signature, activities of certificate authority). Information security and present legislative system of the Czech Republic and the European Union will be explained as well.
Cryptography basic methods and use of these methods to security of electronic information.
