Zero Trust Security: Techniques, Architectures, Models, and Applications in 6G

Dear Colleagues,

The 6G network will be a fully connected world with integrated terrestrial wireless and satellite communications. By integrating satellite communications, 6G mobile communications will enable seamless global coverage. More importantly, with the development of the 6G network, we will be closer to the goal of realizing the Internet of Everything (IoE). However, the high density and wide coverage of 6G networks will face more security threats. Hence, 6G must adopt new network security methods to provide a safer environment for wireless applications.

Zero Trust Architecture (ZTA) is a new security concept proposed to eliminate implicit trust. ZTA assumes all users, devices, and applications are untrusted. As a result, ZTA performs dynamic verification and validation before each official authorized access to network resources. ZTA can be used in various applications in 6G networks, since it has real-time evaluation and authorization which can deny all access requests that are not confirmed. Meanwhile, the two main characteristics of blockchain technology, data immutability, and decentralization can be applied to solve the problem of dynamic trust management when it comes to ZTA.

This Special Issue focuses on all types of Zero Trust technologies, architectures, and their applications in 6G networks, adding a trust management framework centered on blockchain technology if necessary, or using more sophisticated trust management methods.

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.
