Abstract: Methods, systems, and devices for wireless communication are described that support security key derivation for handover. A network entity (e.g., an access and mobility function (AMF)) may establish an access stratum (AS) key to ensure secure communications between a user equipment (UE) and a base station. If the UE relocates to a new network entity (e.g., target network entity), the initial network entity (e.g., source network entity) may perform a handover procedure to the target network entity. In some aspects, the network entities may derive a unified AS key for the handover procedure. Additionally, the network entities may utilize one or more intermediate keys (e.g., refreshed intermediate keys) derived from, in part, respective freshness parameters for the handover procedure. The target network entity may then utilize the derived intermediate keys to derive the AS key for the handover procedure and establish communications with the UE.

Abstract: Aspects directed towards steering of roaming (SoR) are disclosed. In one example, a communication from a public land mobile network (PLMN) is received by a user equipment (UE) in which the communication indicates an acceptance of a UE registration with the PLMN. This example further includes performing a determination of whether an SoR indicator associated with a home PLMN (HPLMN) is embedded within the communication. The UE then manages PLMN selection according to the determination. In another example, a UE is configured to operate according to an SoR configuration in which the UE is configured to ascertain whether an SoR indicator is embedded within a communication from a PLMN. An SoR indicator associated with an HPLMN is then generated and subsequently transmitted from the HPLMN to the UE via the PLMN.

Abstract: Systems and techniques are disclosed to facilitate the sponsored connectivity of a user equipment on a serving network so that the UE may access a service whose connectivity is sponsored by an application service provider. In an embodiment, an application service provider server comprises a transceiver and a processor. The transceiver receives, from an intervening network through which the application service provider server sponsors access to the service, an authentication information request based on an attach request from a user equipment (UE). The authentication information request comprises a client token based on a pre-existing credential established with the application service provider server and being unrecognizable as a cellular access credential to the network. The processor determines authentication information based on the pre-existing credential accessible by the application service provider server in response to the authentication information request. The transceiver transmits the authentication information in a response to the network, and the authentication information assists in authentication between the UE and the network for sponsored access to the service based on the pre-existing credential.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A method includes transmitting a request to a serving network with a nonce and a signature request directed to a network function of the serving network, receiving a response to the request from the serving network, and authenticating the serving network based on the signature of the network function. The nonce may provide replay protection. The response may include a signature of the network function. The request sent to the serving network may include a radio resource control (RRC) message or a tracking area update (TAU) request. The serving network may be authenticated using a trusted third party to verify a certificate associated with the serving network.

Abstract: The present disclosure provides techniques that may be applied, for example, for providing network policy information in a secure manner. In some cases, a UE may receive a first message for establishing a secure connection with a network, wherein the first message comprises network policy information, generate a first key based in part on the network policy information, and use the first key to verify the network policy information.

Abstract: In order to mitigate the security risk posed by the insertion of a relay node within a communication network, both device authentication and subscriber authentication are performed on the relay node. Device and subscriber authentication may be bound together so that a relay node is granted access to operate within the network only if both device and subscriber authentication are successful. Additionally, a communication network (or authentication node) may further verify that a subscriber identifier (received as part of subscriber authentication) is associated with the corresponding device type (identified by the device identifier in the corresponding device authentication) as part of the subscriber authentication process.
