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: A primary authentication procedure is triggered to derive an authentication key for a home network. The authentication key may be used for interworking between network types. For example, a home network primary authentication mechanism may be triggered for interworking from Evolved Packet System (EPS) to 5GS. When a user equipment (UE) moves between network types, the security context and authentication may be different or incompatible. For example, an authentication key may be missing, which may be needed for authentication in one of the network types. Authentication key support may be determined and registration/authentication may vary based on that support. When there is no support for the authentication key, a reauthentication process may be performed.

Abstract: Presented are systems and methods for authorization of proximity based services. A first wireless communication device may send, to a second wireless communication device, a message to access a network via the second wireless communication device as a relay node, using at least one authentication and key management for applications (AKMA) service. The message may include an AKMA key identifier (A-KID) and a freshness parameter. The first wireless communication device may generate a validation token to validate against another validation token of the second wireless communication device. The first wireless communication device may generate the validation token using the freshness parameter and a proximity based service function (PBSF) key (KPBSF).

Abstract: Method, systems and devices for wireless communication. The method includes protecting privacy of a transmitted network slice selection assistance information (NSSAI) between a user equipment and a base station. The method includes receiving a temporary NSSAI (T-NSSAI) from an access and mobility management function (AMF) to the base station, the T-NSSAI comprising at least one temporary single NSSAI (T-S-NSSAI) and storing the T-NSSAI in the base station. The method also includes receiving a radio resource control (RRC) signaling message from the user equipment to the base station, the RRC signaling message comprising a T-S-NSSAI corresponding to an allowed single NSSAI (S-NSSAI); and selecting the AMF based on the T-S-NSSAI.
