The students should become conversant with the essential quantitative methods used in computer science, management, operations research and econometrics as well as with statistical methods for data collection and data mining. They should become familiar with optimization methods used for decision making process for problem - solving and should be able to apply quantitative methods using computer packages Excel and SPSS.

The students should obtain theoretical and practical knowledge necessary for the analysis and synthesis of modern cryptosystems intended for working in different communication scenarios through open communication channels and public computer networks. They should obtain theoretical knowledge for observing fundamental links between information measures of uncertainty, channel capacity and decoding error on one side and relevant indicators in the synthesis of cryptosystems and systems for cryptographic key distribution.

This research paper is a form of testing the candidate on the doctoral study level and is the first relevant verification statement from the mentor about the candidate. It is focused on projects that include practical problems and should finalize part of knowledge from previously covered courses: DSP NSZ 01 and DSP NSZ 02. Through this research paper, we test the ability of the candidate to independently perform complex and detailed analysis of some problem.

The students should be able to perceive the complexity of the procedures of cryptanalysis and become conversant with the basic mathematical apparatus necessary for their implementation. They should be able to classify the attacks on symmetrical cryptosystems, evaluate their efficiency and complexity of the attacks. They should describe the main methods of cryptanalysis of symmetrical cryptosystems and apply the examined methods to several well-known block ciphers and stream ciphers.

This research project is a form of testing the candidate on the doctoral study level and is the second significant verification statement from the mentor about the candidate. It puts emphasis on projects that include practical problems and should finalize part of knowledge from previously covered courses: DSP NSZ 01, DSP NSZ 02, DSP NSZ 03, DSP NSZ 04 and DSP NSZ 05. This research paper tests the ability of the candidate to independently perform complex and detailed analysis of the given problem.

The aim of this course is to enable students to obtain necessary knowledge and experience through solving certain issues and tasks and recognizing possibilities for applying previously obtained knowledge in practice. This research project is the continuation of research paper from the second semester. This research project tests the ability of the candidate to perform complex and comprehensive analysis of some problem. It puts emphasis on practical problems that should finalize part of knowledge from previously covered courses. The students should be able to apply basic, theoretical-methodological, scientific-professional and professional applicative knowledge and methods when solving concrete issues within the chosen field. Within this research project, the students analyze the problem, its structure and complexity and based on the analyses conducted, they draw conclusions concerning the possible ways for its solving. By analyzing and studying the literature and other sources, the students become conversant with methods used for creative solving of new tasks and engineering practice.

This course represents the continuation of the research project from the third semester. The students should become conversant with the mode, structure and form of writing dissertation after completing analyses and other activities that are performed within the stated topic of the doctoral dissertation. By doing scientific-research projects, the students obtain practical knowledge necessary for creative work and writing research papers that should include the description of the issue, methods and procedures applied, and the results obtained, and should make scientific contribution to development of science and application of their scientific research in practice. In addition, the goal of writing and defense of the doctoral dissertation is to enable students to obtain necessary experience through solving complex issues and tasks and finding possibilities for applying previously obtained knowledge in practice.

The students should obtain knowledge concerning the mode, structure and form of writing the doctoral dissertation after completing research and other activities done within the given topic. By doing this doctoral dissertation, the students obtain hands-on experience necessary for creative work and writing essays that should contain problem description, methods and procedures applied, and results achieved, and should make scientific contribution to development of science and application of their scientific research in practice. Besides, the goal of writing and defending the doctoral dissertation is to enable the students to develop skills that would enable them to adequately present their research results and work in public and respond to possible comments and questions concerning their presentation.
