Course detail

Applied Cryptography

FEKT-TAKRAcad. year: 2015/2016

Basic terms, secrecy theory. Symmetric cryptosystems - stream ciphers, block ciphers, standards of symmetric ciphers, key management and distribution. Asymmetric cryptosystems - RSA, DL and EC types of cryptosystems, key agreement, standards of asymetric cryptosystems. Hash and other auxiliary cryptographic functions, data integrity, authentication, digital signatures. Public key infrastructure, modern cryptographic services. Quantum cryptography. Introduction to the cryptoanalysis, attacks on cryptosystems and their defence.

Learning outcomes of the course unit

Students will be introduced to applications of cryptographic mechanisms in communications and networks. They will learn the basic principles of information system security. On completion of the course, students will be able to explain the principles of modern symmetric and asymmetric cryptography.
