Cryptographic key distribution algorithms

Liubomir CHIRIAC, Natalia JOSU, Violeta BOGDANOVA — Thu, 20 Jun 2024 00:45:23 +0000

This article examines public key exchange algorithms applying the Diffie-Helmann-Merkel algorithm for commutative groups and the Stickel-Shpilrain algorithm for non-commutative groups. The protocols Diffie–Hellman–Merkel and Stickel–Spilrain key exchange are mathematical methods for the secure exchange of cryptographic keys over a public channel. The Diffie-Helmann-Merkel algorithm is one of the first public key protocols in cryptography. The authors examine the implementation of the respective algorithms through abelian and non-abelian algebraic structures based on the discrete logarithm problem. The man-in-the-middle attack is also examined. Examples are constructed that illustrate the operation of the mentioned algorithms

Task-based learning approach in Java programming

Tatiana CHIRIAC — Thu, 20 Jun 2024 06:24:15 +0000

The task-based learning methodology is examined in this study within the framework of the Java programming language. It emphasizes the idea that students are better able to draw connections between the skills they are learning in a course and real-world issues when they use a task-based approach when studying programming. The purpose of the provided research questions is to clarify various features of the task-based approach found in specialized literature and to demonstrate how it may be used when learning Java programming to construct a task-based program. Choosing activities, integrating training, and establishing explicit objectives are all necessary when creating a task-based program that takes into consideration the needs of the learners.

Reasons why assembly language remains fundamental in modern programming

Ala GASNAS, Angela GLOBA — Thu, 20 Jun 2024 09:10:19 +0000

This article explores the importance of assembly language in modern programming. While high-level languages dominate software development widely, assembly language remains essential in certain domains. It provides precise and direct control over hardware and system resources, allowing performance optimization and access to specific processor features. Developers of drivers, real-time systems, and low-level embedded applications particularly benefit from knowledge of assembly language. Thus, assembly language remains a fundamental tool for those seeking to deeply understand hardware operation and optimize the performance of computer systems.

The development of professional skills through blogs and personal websites

Tatiana VEVERITA — Thu, 20 Jun 2024 09:35:55 +0000

The article proposes and evaluates how a teacher's blog and personal website can become useful learning tools for acquiring professional skills. Learners are required, after opening a blog/personal website, to document the activities carried out in the classroom, reflect on these activities during the training period, and use tags as elements of self-reflection on the skills developed during the training. To monitor the learners' progress in developing the teacher's blog/personal website, a questionnaire is used at the beginning and the end of the training period. This information is supplemented with an analysis of the content published on the blogs/websites. The study will also reveal whether the participating teachers consider the blogs/websites valid tools for acquiring professional skills, whether they are satisfied with the teaching-learning process, and whether they would recommend these tools to other educators.

Increasing the motivation for practicing physical exercise in high school students

Daniel-Dragos OPRESCU — Thu, 20 Jun 2024 09:54:09 +0000

Nowadays, the motivation to practice physical exercise, rhythmic and organized, has become a problem, both because of social trends that encourage the individual to be sedentary, and because of the fact that there are quite a lot of ways, attractive for teenagers, to spend their free time. Convenience, self-satisfaction, lack of competitive spirit has also transferred to the classroom these behaviours of teenagers, who try to avoid participating in Physical Education classes. Identifying methods and intervention tools to stimulate motivation and the desire to be involved is not an easy task, which puts the teacher in a position to probe his creativity and knowledge. In this sense, we have tested and we try to present you some ways to reach students, to make them leave their comfort zone and actively participate in the activities carried out in Physical Education class.
