Embedding a pairwise key distribution approach in IoT systems is challenging as IoT devices have limited resources, such as memory, processing power, and battery life. This paper presents a secure and lightweight approach that is applied to IoT devices that are divided into Voronoi clusters. This proposed algorithm comprises XOR and concatenation…

This paper presents a novel approach for mitigating wormhole attacks on wireless networks using propagation delay timing. The wormhole attack is a persistent security threat that threatens the integrity of network communications, potentially leading to data theft or other malicious activities. While various methods exist for combating wormhole…

Digital literacy has become crucial for functionality and productivity in academics, work, and everyday community lives. However, easy access to digital technologies, accompanied by limited digital literacy, can expose users to the dangers that lurk in the digital world. Young people, who are frequent users of these technologies yet have less…

This paper, based on data from our second nationwide survey of cybersecurity among local or grassroots governments in the U.S., examines how these governments manage this important function. As we have shown elsewhere, local government cybersecurity is increasingly important because these governments are under constant or nearly constant…

Background/purpose. This research was conducted to address the growing need for more secure, transparent, and efficient solutions for the issuance and management of university degrees. The main purpose of the study is to evaluate which Blockchains are best suited for this application, aiming to enhance the reliability and speed of degree-related…

Introduction: The digital era is reshaping not only technology and economy but also the legal systems governing democratic societies. The rapid emergence of artificial intelligence, big data, and digitisation calls for proactive adaptation of legal frameworks. This article explores the intersection of digital transformation and the rule of law,…

Detecting and mitigating wormhole attacks in wireless networks remains a critical challenge due to their deceptive nature and potential to compromise network integrity. This paper proposes a novel approach to wormhole detection by leveraging propagation delay analysis between network nodes. Unlike traditional methods that rely on signature-based…

The research was conducted to determine whether there is a relationship between adolescents' social media privacy protection skills and social media addiction levels. A total of 499 adolescents between the ages of 15 and 18 participated in this correlational study. The study used a Personal Information Form, the Social Media Privacy Protection…

Over the last two decades, online safety education has emerged as a new field of research focusing on concerns about a myriad of cyber risks. These risks range from online sexual exploitation through to the reproduction of social inequalities. The main assumption underlying this field is that online risks can be mitigated via educational…

The human aspects of cyber security are fundamental as these are interlinked with processes and technology in building resilience against an evolving and complex threat landscape. It is vital to teach future cyber security specialists sufficient knowledge about human aspects in order to strengthen the defences and defend against malicious actors.…

After the Cold War period, with the restructuring of the world, globalization, the revolution in information technology and the reconstruction of capitalism have created a new type of society, the "network society". The dependence of countries on information technologies, especially the internet, has increased day by day, and it has…

STEM (science, technology, engineering, mathematics) hackathons have been conducted to offer opportunities for diverse participants to work collaboratively and intensely on tasks within a short period. However, most literature about hackathons does not offer theoretical discussions on the affordances of such learning contexts for school students.…

The role of ethics becomes even more significant given the huge advent and increase of cyber-criminal activities in cyberspace. It has become an urgent necessity to curb the menace of unethical practices in cyberspace and contribute ethical guidelines to a safe and secure digital environment. To minimize the growth of cybercrimes and unethical…

We present a concrete situation where there is a difference between the theoretical security of a cipher and its limitations when implemented in practice. Specifically, when entering a PIN, smudges on the keypad substantially reduce its security. We show how the number of possible keys in the presence of the "smudge attack" can be…

Computer-supported learning technologies are essential for conducting hands-on cybersecurity training. These technologies create environments that emulate a realistic IT infrastructure for the training. Within the environment, training participants use various software tools to perform offensive or defensive actions. Usage of these tools generates…
