Abstract:

The development of society, business, and the economy are highly hampered and dependent on the functioning of critical information infrastructures, which are strongly linked to modern information and communication networks and the services they provide.

The article presents a successfully used methodology for training students of "information security" engineering majors, which increases students' competence and professionalism. The article focuses on the use of basic cryptographic algorithms.

The AES (Encryption Keys and Rounds) encryption algorithm is a block cipher consisting of a block of length 128 bits that use the same key to perform several rounds of encryption.

The authors of the article present a methodology for researching information encryption algorithms. In this context, emphasis is placed on one of the main problems, namely ensuring the protection of information. Attention has also been paid to the types of encryption, speed, and security of information. The emphasis of the article is directed to the presentation and analysis of data protection methods and solutions. The open-source software crypto tool 2.1 was used. for testing and analysis by students in the engineering disciplines "of information security" and "data encryption". It offers a wide range of tools that allow it to be used to analyze and understand both classical and modern encryption.

The use of the software environment crypto tool 2.1. by the students trained in the engineering majors "Information Security" and "Hardware and Software Systems" contributes to the more effective testing and analysis of the processes taking place in the encryption with the use of different types of algorithms. The simulation models developed in this environment provide an opportunity for trainees to follow and learn engineering work: creating a project to study classical and modern encryption, simulating their operability, testing, conducting real-time research using virtual tools, and debugging errors.

The goal is for students to get to know and analyze the types of cryptographic algorithms, how they work, and their security and speed, in order to acquire the necessary knowledge and skills in using cryptographic algorithms in various engineering projects. This contributes to increasing the efficiency and quality of engineering education.
