New Challenges in IoT Security

Dear Colleagues,

In recent years, IoT systems have become ubiquitous for our daily activities.

The Special Issue, New Challenges in IoT Security, seeks to collect contributions from researchers involved in designing and working with IoT systems, facing all sorts of security challenges. The Internet of Things (IoT) is rapidly transforming industries, societies, and daily life by connecting billions of devices across diverse environments. From smart cities and healthcare systems to industrial automation and critical infrastructure, IoT technologies are enabling unprecedented efficiency, intelligence, and connectivity. However, this explosive growth also presents critical security and privacy challenges. The increasing heterogeneity of devices, constrained computational resources, evolving attack surfaces, and large-scale data exchange have made IoT systems particularly vulnerable to cyber threats. These challenges demand innovative, multidisciplinary solutions that can ensure trust, resilience, and secure integration of IoT into the digital ecosystem.

This Special Issue on “New Challenges in IoT Security” seeks to bring together cutting-edge research and practical insights from the global community to address emerging issues in IoT protection. We invite original contributions that explore novel security models, architectures, algorithms, and frameworks aimed at safeguarding IoT environments. Topics of interest include, but are not limited to, lightweight cryptography for resource-constrained devices, intrusion detection and anomaly detection in IoT networks, secure communication protocols, privacy-preserving data management, AI- and blockchain-enabled security solutions, trust management frameworks, secure edge and cloud integration, and real-world case studies of IoT security deployments.

By uniting diverse perspectives, this Special Issue aims to foster dialogue between academia, industry, and policymakers. Contributions will not only advance theoretical understanding but will also highlight practical implementations and future directions for IoT security. The goal is to provide a comprehensive resource that will help researchers, practitioners, and decision-makers build resilient, trustworthy, and scalable IoT ecosystems capable of withstanding current and future cyber threats.

We warmly encourage the research community to submit their latest findings and join us in shaping the next generation of secure IoT technologies.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
