Learning outcomes of the course unit

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.

Prerequisites

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Methods of educations are described in the article 7 of the BUT’s Study and Examination Regulation. Techning methods include lectures and consultations. Course is taking advantage of e-learning (Moodle) system. Students have to deliver 1 project assignment.

Assesment methods and criteria linked to learning outcomes

The maximum of 30 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 70 points can be gained during the final exam.

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 complex systems, such as credential systems, e-voting schemes, e-cash schemes and similar constructions.
