AI-Driven Secure Communications and Networking in 6G Integrated Satellite-Terrestrial Networks

Dear Colleagues,

Integrated satellite–terrestrial networks (ISTNs) are rapidly evolving to meet the demands of next-generation wireless systems, particularly in the context of 6G. Such networks are expected to play a critical role in providing seamless global connectivity, ultra-reliable low-latency communications and massive machine-type communications. This Special Issue aims to explore AI-driven theory, technologies and real-world applications for secure communications and networking in ISTNs, emphasizing their integration with cutting-edge 6G technologies.

Topics of interest include, but are not limited to:

• AI-secured 6G-enabled IoT over ISTNs
• AI-enhanced physical-layer security
• AI-driven secure beamforming and waveform design
• Intelligent spectrum sharing in ISTNs
• Grant-free multiple access techniques
• Integrated sensing and communications (ISAC)
• Federated or split-learning for privacy-preserving authentication
• Blockchain–AI hybrid frameworks
• AI-aided secure networking over ISTNs
• AI-driven network optimization
• Multi-orbit satellite networking

This Special Issue seeks to foster a multidisciplinary discussion that advances the design, implementation and application of ISTNs in the 6G era. We invite high-quality submissions that include theoretical insights, algorithmic developments, experimental validations and field trials, all aimed at paving the way for robust, secure and efficient integrated satellite–terrestrial communication networks.

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-anonymized 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.
