Advances in Post-Quantum Security

Dear Colleagues,

The purpose of this Special Issue, Advances in Post-Quantum Security, is to provide a dedicated platform for pioneering research, innovative algorithms, and system-level solutions that address the rapidly growing security landscape shaped by the emergence of quantum computing. As quantum computing evolves from a theoretical concept to a practical capability, its implications extend beyond traditional cryptanalysis, which impacts secure communications, encrypted algorithms, authentication frameworks, and entire digital infrastructures. The urgency to prepare for this shift has accelerated global attention towards quantum-secure and quantum-enabled security mechanisms.

This Special Issue welcomes contributions that advance both defensive and enabling aspects of quantum security. The scope includes, but is not limited to, quantum-resistant cryptographic primitives, quantum key distribution and communication protocols, trusted execution environments for quantum devices, secure architectures for IoT and 5G/6G networks, artificial intelligence-driven threat detection, and applied demonstrations of quantum-secure systems. By incorporating this interdisciplinary approach, the Special Issue aims to close the gap between theoretical and practical proposals, scalable deployments, and enabling solutions that are not only mathematically perfect but also operationally viable for real-world applications.

While the existing literature provides extensive insights into post-quantum cryptographic algorithms, security frameworks, and initial standardization efforts led by NIST, much of the published work remains confined to algorithmic design or conceptual analysis. There is comparatively limited research to explore how quantum-secure approaches integrate with heterogeneous communication networks (IoT/ 5G/6G), cloud infrastructures, AI-driven monitoring systems, and emerging quantum-enabled technologies.

This Special Issue moves beyond core digital security concepts by emphasizing the transitional phase toward quantum-era security systems, where classical and quantum technologies can coexist. It encourages submissions that address real-world applications and considerations such as latency, resource constraints, interoperability, hardware requirements, and migration strategies. Ultimately, this Special Issue serves as a bridge between theoretical advancements and their implementation in modern digital ecosystems. It aims to provide a reference point for researchers, industry practitioners, and policymakers who are seeking to design, adopt, and govern robust security infrastructures capable of withstanding the emerging quantum threats and leveraging quantum technologies for secure communication.

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.
