Understand the security architecture of 5G/6G — mutual authentication, subscriber privacy, zero-trust principles, and per-slice protection across the entire network.
5G uses the 5G-AKA protocol for mutual authentication between the device and the network, deriving fresh keys for each session.
The permanent identity (SUPI) is encrypted into a concealed identifier (SUCI) so it is never sent in the clear, defeating IMSI-catcher tracking.
The service-based architecture applies zero-trust principles, and every network slice is isolated with its own security policy.
Threat modelling addresses signalling attacks, DDoS and virtualization risks, while supply-chain assurance secures hardware and software components.
