Advances in Cryptography for IoT in the Era of Quantum Computing

Dear Colleagues,

The rapid expansion of the Internet of Things (IoT) has transformed industries by enabling seamless connectivity and automation. However, this interconnected ecosystem is highly vulnerable to cyber threats due to the resource constraints of IoT devices, their large attack surface, and the reliance on traditional cryptographic mechanisms that may not be optimized for constrained environments. With the advent of quantum computing, classical cryptographic algorithms—especially those based on RSA, ECC, and DSA—face a significant threat, necessitating the development and adoption of quantum-resistant cryptographic techniques.

This Special Issue aims to address the emerging challenges in IoT security by exploring cutting-edge cryptographic techniques tailored for constrained IoT devices, both in classical and post-quantum contexts. Topics of interest include (but not limited to) the following:

•    Lightweight cryptographic protocols; 
•    Quantum-resistant key exchange mechanisms;
•    Blockchain-based security frameworks;
•    Homomorphic encryption for secure IoT data processing;
•    IoT hardware security;
•    Hybrid security models that integrate classical and quantum-safe techniques.

We encourage submissions that propose novel cryptographic solutions, analyze the impact of quantum threats on IoT security, and discuss practical implementations of post-quantum cryptography in real-world IoT applications. Researchers, practitioners, and policymakers are invited to contribute original research, case studies, and comprehensive reviews addressing the evolving security landscape of IoT in the quantum computing era.

We look forward to receiving your contributions.

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. 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.
