In 5G, a new security network function, Authentication Server Function (AUSF) has been introduced in the 5G core (5GC) to manage the UE authentication using the SUCI or the SUPI and to manage the root session key KAUSF. The AUSF stores the root session key KAUSF and further keys are derived from this key.
