Transactions on Engineering and Computer Science

Cybersecurity and blockchain technology address the protection of digital systems, data, and infrastructure against evolving threats, alongside the decentralised technologies increasingly used to secure transactions and information. This specialty collection within Transactions on Engineering and Computer Science publishes original research articles, reviews, and technical contributions examining security mechanisms, cryptographic methods, and blockchain-based systems across computing environments.

The collection welcomes manuscripts spanning network and information security, cryptography, blockchain architecture and consensus mechanisms, cryptocurrency and decentralised finance technology, intrusion detection, and the security challenges associated with cloud, mobile, and Internet of Things environments. Research in this area carries substantial importance given the growing scale and sophistication of cyber threats worldwide, making robust security research and trustworthy decentralised systems essential to protecting digital infrastructure across sectors. The collection also provides a natural home for interdisciplinary security research bridging computer science, engineering, and applied cryptography.

Because cybersecurity and blockchain research frequently intersect with software engineering, networking, and applied cryptography, contributions to this collection often reflect collaboration between security researchers, cryptographers, and systems engineers working to build resilient and trustworthy digital infrastructure. The collection is intended for an international audience of researchers, security professionals, and industry practitioners, whether their work addresses theoretical cryptographic foundations or applied security and blockchain system design.

Accepted articles are organised within this collection, helping researchers with an interest in cybersecurity and blockchain technology locate relevant studies more easily. Researchers and practitioners are encouraged to share findings that strengthen digital security and advance decentralised system design, from foundational cryptographic research to applied studies in network security and blockchain technology worldwide.
