“…According to the literature, when dealing with the SE educational challenges, one common strategy is to integrate projects and/or games into the pedagogical design to attract students' interests and increase their engagement, while another strategy is to employ concept mapping [6] to address the concept-intensive feature of this subject. This paper mainly focuses on the latter to identify and review the related work, as concept mapping aims at knowledge representation, and so does our research.…”

“…Based on our critical reflection, we tried but questioned the usage of concept mapping for teaching SE knowledge. Although being able to build graphical knowledge representations (namely concept maps) to capture and organise the underlying concepts and their relationships [6], concept mapping seems to be suitable only for explaining small groups of neighbouring concepts. If involving concepts far apart from each other (or even across different domains), the corresponding concept maps would become visually overwhelming and in return negatively affect students' understanding.…”

In the university curriculum, software engineering (SE) is frequently perceived as a difficult course to study due to its concept-intensive nature.[Objectives]: We aim to investigate if and how we can help students conveniently understand and memorise the numerous and various SE concepts.[Method]: We employ critical reflection as the research method to qualitatively examine our educational activities, teaching materials, and students' learning effects.[Results]: By focusing on the paired structural model of knowledge representation, we propose to utilise tangentially-paired concepts together with the conventional bipolar-paired concepts to facilitate SE education. In particular, we have identified three types of tangentially-paired concepts with deriving (stemming), analogical, and cloning relationships respectively. [Conclusions]: Exploiting paired SE concepts can act as an efficient educational approach that supplements the existing strategies for teaching SE knowledge.

“…The NATO standards essentially define four security perimeters in terms of the risk for the signal interception: 0-20 meters (high risk), 20-50 (medium risk), 50-100 meters (low risk) and more than 100 meters (very low risk). More information about compromising emanations can be found in (Martin, Sunmola, Lauder 2022) [12] and (NCSC, 2021) [13].…”

In this study, a method is proposed in order to evaluate the security of a cryptographic system, which besides of its cryptographic algorithm which is embedded into the system, includes other critical individual units and security mechanisms. If some of these security mechanisms are inadequate, they may reduce the initial security of the system which is provided by the strength of its cryptographic algorithm. The evaluation method combines the strength of the system’s cryptographic algorithm with the strength of all the other security mechanisms and gives a final assessment for the security grade of the whole system. At the end of the study the necessary conditions are presented, for the validity and the duration of the evaluation, taking into account the expected evolution of technology. Keywords: Cryptography, Data encryption, Communication security, Computer security, Data security, Information security.

The information technology and communication (IT&C) market consists of computing and telecommunication technology systems, which also include a variety of audio devices. Preserving the confidentiality of transmitted information through these devices stands as a critical concern across various domains and businesses. Notably, spurious electromagnetic emanations emitted by audio devices can be captured and processed, potentially leading to eavesdropping incidents. The evaluation of electronic devices for potential security vulnerabilities often involves employing Transient Electromagnetic Pulse Emanation Standard (TEMPEST) technology. This paper introduces a novel approach to TEMPEST testing specifically tailored for audio devices. The outcomes of the proposed approach offer valuable insights into TEMPEST equipment testing, aiming to mitigate the potential risks posed by threats exploitable by eavesdroppers in everyday scenarios. The present work delves into the examination of two ubiquitous global electronic devices: a notebook and a pair of in-ear headphones. The symmetrical framework of this study arises from the intrinsic similarity that, despite belonging to distinct categories, both devices possess the capability to emit electromagnetic emissions that contain compromised audio signals. This assertion is substantiated by the measurement results presented herein. The proposed methodology involves the analysis of the audio amplitude modulation (AM) demodulated signal in the frequency domain. This innovative approach not only mitigates operator fatigue but also significantly reduces the testing time required for these devices and instrument running hours and leads to the development of new applications.
