4G networks today use the USIM application to perform strong mutual authentication between the user and his/her connected device and the networks.
The entity hosting the USIM application can be a removable SIM card or an embedded UICC chip.
This strong mutual authentication is crucial to enable trusted services. Security solutions today are already a mix of security at the edge (device) and security at the core (network).
Several security frameworks may co-exist in the future, and 5G is likely to re-use existing solutions used today for 4G networks and the cloud (SEs, HSM, certification, Over-The-Air provisioning, and KMS).
The standard for strong mutual authentication for 5G networks was finalized in 2018.
The need for 5G security, privacy, and trust will be as strong as for 4G if not stronger with the increased impact of IoT services.
Local SEs in devices can not only secure network access but also support secure services such as emergency call management and virtual networks for IoT.
