Abstract: Techniques are disclosed for user equipment authentication in a shared access network environment. In one example, a method comprises establishing, via a first access management entity in a first communication network that has a radio access network associated therewith, a secure connection with a second access management entity in a second communication network to which user equipment subscribes, and facilitating, via the first access management entity, authentication of the user equipment in conjunction with the second access management entity over the secure connection to enable the user equipment to utilize the radio access network of the first communication network to access the second communication network.

Abstract: Systems, methods, and software of performing a store and forward service for mobile terminated messages to user equipment via satellite access. In an embodiment, a home network of user equipment (UE) receives a first message request from an application server that includes a secured packet destined for the user equipment via satellite access, and determines whether the user equipment supports the store and forward service via satellite access. When the user equipment supports the store and forward service, the home network provides integrity protection of the secured packet at the home network by deriving a message authentication code based on the secured packet and a home network key, and send a second message request to a serving network of the user equipment with the secured packet and the message authentication code contained in a home network container.

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: A method is disclosed comprising: establishing an encrypted session with an application function based on a certificate; receiving a request for an application key from the application function using the encrypted session, wherein the request comprises a key identifier relating to a user device and an application function identifier; determining at least one response to the request for the application key from a set of possible responses, the set comprising at least a rejection and a message comprising the application key and a user device identifier; and transmitting the at least one response to the request for the application key to the application function. Furthermore, related methods, apparatuses, computer programs and systems are disclosed.

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.
