Challenges and Advances of Cybersecurity in Cloud-Sensor Digital Infrastructure

Dear Colleagues,

The rapid integration of cloud computing and sensor technologies is transforming digital infrastructure across sectors such as healthcare, power grid, transportation, agriculture, manufacturing, and smart cities. This convergence has enabled scalable, real-time, and intelligent systems driven by vast volumes of data collected from heterogeneous sensor networks and processed via powerful cloud platforms. However, this evolution also introduces complex cybersecurity challenges, including data integrity threats, unauthorized access, privacy leakage, malware propagation, and the vulnerability of distributed edge nodes.

This Special Issue of Sensors invites high-quality contributions that explore emerging security challenges, cutting-edge defense mechanisms, and novel architectures for securing cloud-sensor infrastructures. Topics of interest include, but are not limited to, secure communication protocols, intrusion detection systems, threat modeling, trusted data aggregation, federated learning security, and blockchain-based solutions for distributed sensing environments. We welcome research articles, surveys, and case studies that address both theoretical foundations and practical implementations, particularly those with interdisciplinary insights or industrial relevance.

Through this Special Issue, we aim to foster dialogue and collaboration among researchers, practitioners, and policymakers to advance the state of cybersecurity in next-generation digital infrastructures built on cloud and sensor technologies.

Manuscript Submission Information

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 250 words) can be sent to the Editorial Office for assessment.

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. Sensors 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 2600 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.
