6G infrastructures must ensure reliability, trust and resilience on a globally connected continuum of heterogeneous environments supported by the convergence of networks and IT systems to enable new future digital services. The substantial increase of coverage and network heterogeneity, raises severe concerns that 6G security and privacy can be worse than the previous generations. The 6G network should be a deep integration of emerging AI tools, new hardware components and accelerators, compute and networking functions, IoT and edge nodes. Contemporary security is not designed for serving a massive number of connected and high-mobility heterogeneous devices. CONFIDENTIAL6G emphasizes on privacy preservation and security of sensitive data by focusing on protection of data:
