Using New Technologies in Cyber Security Solutions (3rd Edition)

Dear Colleagues,

In this Special Issue of Computers, we welcome original research articles and comprehensive reviews addressing various aspects of cyber security. Contributions presenting novel technologies, methods, and applications in the field of cyber security are encouraged. Example research areas include, but are not limited to, the following:

• Using blockchain technologies on cyber security solutions;
• Using LLMs, deep learning and active learning on cyber security solutions;
• IoT, virtualization, and cloud computing security;
• Security and privacy issues in metaverse;
• Using pot-quantum cryptographic solutions;
• Secure smart contracts;
• Cyber-attacks on blockchain technology;
• Novel cybercrimes on social media using deepfake technology.

Recently, most daily activities have shifted into the digital realm. While this digital transformation offers numerous benefits, it has also made individuals and organizations increasingly vulnerable to cyber-attacks. According to recent reports, by 2025, cybercrime is projected to cost the global economy approximately USD 10 trillion, making it one of the most profitable illicit sectors worldwide. The volume of cyber-related crimes continues to rise, and no single technique or method has yet proven capable of effectively stopping attackers. As soon as cyber defenders develop solutions to known attacks, cybercriminals respond with new, previously unseen attack strategies—remaining, in most cases, one step ahead.

Emerging technologies such as blockchain, smart contracts, virtualization, large language models (LLMs), deep learning, active learning, and post-quantum crypto offer promising directions for advancing cyber security. Therefore, this Special Issue welcomes original research articles and reviews that apply novel technologies and methodologies to various domains within cyber security. The goal of this Issue is to present innovative ideas, expand scholarly understanding, and provide propose efficient, forward-looking solutions to counteract cybercrime.
