Core security and resilience.

Technologies

• 5G security architecture Authentication, key hierarchy, subscriber privacy and interface protection across the 5G system.
• Security assurance of network products Security test requirements for network functions before deployment.
• Zero trust architecture Per-request authorisation of users, devices and workloads instead of a trusted internal network.
• Restoration and geo-redundancy Failover and restoration procedures so core outages do not take sites off the air.
• Post-quantum cryptography migration Inventorying and replacing public-key algorithms with standardised post-quantum schemes.
