Rules for evaluation and completion of the course

A maximum of 20 points is awarded for the completion of individual tasks. The final oral exam is evaluated with a maximum of 80 points. The final exam consists of a presentation of an original professional or scientific article written in Czech/English and in the range of 4-6 pages in a two-column format (60 points) and a discussion on issues in the field of advanced cryptography (20 points). The article must be focused on the field of cryptography or information security. 

Aims

The goal of the subject is to introduce students the advanced methods of contemporary cryptography, which are necessary for the construction and implementation of modern cryptographic systems. The student will learn fundamental cryptographic primitives, in particular the commitment schemes, group signatures, interactive proof systems, and more advanced cryptographic technologies such as attribute-based credentials, cryptocurrencies and blockchain, post-quantum cryptography.  
Upon the completion of the subject, the students will be able to understand the design of modern cryptographic constructions presented in the form of scientific publications. Student will be able to use basic cryptographic primitives (commitments, proof systems and signature schemes) for the construction of complex schemes. Students will be able to provide a security analysis for designed schemes based on formal models using provable security.
