- Abstract
- Reliable communications are an important part of public missions. Previously, public safety networks used dedicated networks based on narrowband technology. However, there is current interest in leveraging mobile-based BroadBand (BB) technologies. Therefore, in this paper, we discuss technologies named ZTB (Zero Trust Blacknet) that can safely access MissionCritical (MC) services in broadband mobile-based public safety networks. A mixture of rapidly deployable tactical bubbles and commercial access networks, zero trust zones require rigorous verification before access to MC server zones. First, we made a kind of tactical bubble with Open5GS and srsRAN. Next, mobile communication with commercial mobile devices takes place in this bubble. We also develop the ZTB Manager, Gateway and Agent functions to provide secure access to the MC server based on the Zero Trust Architecture (ZTA) and Single Packet Authorization (SPA) mechanism. ZTB will help increase the reliability of communications over mobile broadband public safety networks.
