Abstract: Based on determining (S211) that each of one or more NRFs of a mobile communication network system has become unavailable, switching (S213) to an NRF-unavailable state in which a validation of an NF service consumer based on an access token for a service request towards an NF service producer is relaxed is performed. The service request is sent (S215) towards the NF service producer, the service request comprising at least an indication of the NRF-unavailable state. Upon receipt (S221) of the service request, the service request is processed (S223) based on the indication of the NRF-unavailable state.

Abstract: Techniques for authentication and key management for applications (AKMA) in a communication network are disclosed. For example, a method comprises receiving an indication from an application function that a first expiry time of a first application function key, generated using a first random value and configured to enable user equipment to participate in a session with the application function, has expired. The method generates a second application function key for the application function, using a second random value, with a second expiry time.

Abstract: There are provided measures for improved robustness of artificial intelligence or machine learning capabilities against compromised input. Such measures exemplarily comprise receiving, from a first machine learning model training data collection entity, first machine learning model training input data, analyzing said first machine learning model training input data for malicious input detection, deducing, based on a result of said analyzing, whether said first machine learning model training data collection entity is suspected to be compromised, and transmitting, if said first machine learning model training data collection entity is suspected to be compromised, information to a core network entity indicative of that said first machine learning model training data collection entity is suspected to be compromised.

Abstract: Systems, methods, and software of performing an Authentication and Key Management for Applications (AKMA) authentication service. An AKMA authentication proxy resides between User Equipment (UE) and a plurality of Application Functions (AFs). The AKMA authentication proxy receive an application session establishment request message from the UE requesting an application session with a first application function, sends a key request message toward an AKMA anchor function (AAnF) requesting AKMA application keys for a plurality of application functions, receives a key response message sent from the AAnF that includes the AKMA application keys, identifies a first AKMA application key for the first application function from the AKMA application keys derived by the AAnF, and forwards the application session establishment request message to the first application function with the first AKMA application key.
