Abstract: This disclosure generally relates to encrypted communication between terminal devices and service applications via a communication network. Such encrypted communication may be based on various hierarchical levels of encryption keys that are generated and managed by the communication network. Such encrypted communication and key management may be provided by the communication network to the terminal devices as a service that can be subscribed to. The various levels of encryption keys may be managed to improve flexibility of the communication network and to reduce potential security breaches.

Abstract: The present document relates to methods, systems, and devices related to digital communication, and more specifically, to techniques related to AUSF selection in the case of dual registrations in AKMA. One example data communication method includes receiving, by a first network function, a request to retrieve an identifier of a second network function that authenticated a terminal from a third function, the request including a parameter. The method also includes transmitting, by the first network function, a response to the third network function that includes the identifier of the second network function that authenticated the terminal that is identified based on the parameter.

Abstract: The present disclosure describes methods, systems and devices for establishing secure communication between a user equipment and a service application in a wireless communication. One method includes receiving, by the user equipment, an authentication and key management for service applications identifier (AKMAID) from an authentication server function (AUSF) upon successful completion of an authentication process for registering the user equipment with the communication network. The method also includes storing, by the user equipment, the AKMAID; deriving, by the user equipment, an application key based on a base authentication key; sending, by the user equipment, a communication request to the service application, the communication request comprising the AKMAID; and receiving, by the user equipment, an application session establishment response to the communication request from the service application to establish a security communication session between the user equipment and the service application based on the application key.
