Zero Trust Architecture for 6G Security

Abstract

The upcoming sixth generation (6G) network is envisioned to be more open and heterogeneous than earlier generations. This challenges conventional security architectures, which typically rely on the construction of a security perimeter at network boundaries. In this article, we propose a softwaredefined zero trust architecture (ZTA) for 6G networks, which is promising for establishing an elastic and scalable security regime. This architecture achieves secure access control through adaptive collaborations among the involved control domains, and can effectively prevent malicious access behaviors such as distributed denial of service (DDoS) attacks, malware spread, and zero-day exploits. We also introduce key design aspects of this architecture and show the simulation results of a case study, which shows the effectiveness and robustness of ZTA for 6G. Furthermore, we discuss open issues to further promote this new architecture.

Light-Weight Security Protocol and Data Model for Chip-to-Chip Zero-Trust

“…In [15], a novel ZT aligned method for detecting run-time Trojans in untrusted commercial off-the-shelf (COTS) processors is provided. A software-defined ZT architecture for sixth generation (6G) networks is proposed in [24], which has the potential to establish a flexible and scalable security framework. This architecture relies on adaptive collaboration among control domains to enable secure access control, and it provides effective protection against malicious access behaviors, including distributed denial of service (DDoS) attacks, malware propagation, and zero-day exploits.…”
