Entry knowledge

Foundations of cryptography in the extent of the Bachelor and Master level programs, e.g. BZKR-IBE a TCPT-IBE. courses

Rules for evaluation and completion of the course

The maximum of 60 points is given upon completion of the individual project. The requirements on the completion of the projects are described in the annual supervisor’s notice.  The maximum of 40 points can be gained during the final exam.
The conditions for the successful course completion are stated in the yearly updated supervisor’s notice.

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.
