name: IAK
full_form: Initial Authentication Key
context: set up the initial trust. The initial trust can be implemented by 1) OAM issued certificates, 2) an Initial Authentication Key (IAK), or 3) OAM issued signature of certain NF profile parameters. The initial trust shall be implemented by one of these mechanisms. The requirements are the following: 1. The deployment of the initial trust as OAM certificate requires the configuration of a local CA used for 5GC NFs within SBA domain (specifically within the same security trust domain of the NF managed by the OAM system), and the configuration of the root CA public certificate of the local CA as trust anchor in the operator CA/RA. 2. The deployment of the initial trust as IAK requires the distribution of such key out-of-band between the operator CA/RA and the NF via OAM system. This initial credential is used as initial trust by the operator CA/RA to authenticate the NF. The management aspects of IAK are left to implementation (e.g., provisioning, one time use, etc.). 3. The deployment of
description: The Initial Authentication Key (IAK) is a critical network attribute used for setting up the initial trust between the operator CA/RA and the Network Function (NF). It is one of the mechanisms for implementing initial trust, alongside OAM issued certificates and OAM issued signature of certain NF profile parameters.
explanation: The context explicitly mentions IAK as a key used for initial authentication, highlighting its role in establishing trust between network components. This aligns with the definition of a Parameter, which includes critical network attributes such as identifiers and keys.
