Abstract: This disclosure generally relates to transferring encryption key to a VPLMN in wireless communication. Performed by first network element, the method includes: transmitting a query message to a second network element, to request an identification of a NF entity, wherein the query message comprises an identifier of a wireless device, and wherein the network function is an entity in the VPLMN for storing encryption keys; receiving, from the second network element, a response to the query message, the response comprising the identification of the NF entity; and transmitting, to the NF entity based on the identification of the NF entity, a first message comprising an encryption key, wherein the AF entity is located in the HPLMN or a DN external to the HPLMN and the VPLMN.

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: Techniques are described to perform network relay security. An example wireless communication method includes receiving, by a network device, a request message that includes an identifier associated with a first communication device; determining, by the network device in response to the receiving, that the first communication device is authenticated based on a local policy of the network device; and sending, by the network device in response to the determining, a message to a second communication device to relay to the first communication device, where the message indicates that the identifier is rejected by the network device for communication with the first communication device, or where the message indicates that the first communication device is triggered to send another identifier.
