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: Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may receive a timing variable from a network while the device is in a connected mode. The device may then use the timing variable for D2D discovery message authentication. The device may compare the timing variable with a local timing variable to determine whether a difference between the two variables is within a maximum allowable offset. The device may announce the D2D discovery message to another device when the difference is within the maximum allowable offset.

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: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes performing an extensible authentication protocol (EAP) procedure with an authentication server via an authenticator. The EAP procedure is based at least in part on a set of authentication credentials exchanged between the UE and the authentication server. The method also includes deriving, as part of performing the EAP procedure, a master session key (MSK) and an extended master session key (EMSK) that are based at least in part on the authentication credentials and a first set of parameters; determining a network type associated with the authenticator; and performing, based at least in part on the determined network type, at least one authentication procedure with the authenticator. The at least one authentication procedure is based on an association of the MSK or the EMSK with the determined network type.

Abstract: A user equipment (UE) may be configured to transmit a registration message to a network to establish a secure connection for non-access stratum (NAS) messages between the network and a UE, the secure connection based at least in part on a UE identifier and security capabilities of the UE included in the registration message. The UE may then exchange NAS messages with the network over the secure connection. The UE may also establish, in response to the registration message, an authentication protocol with the network and encrypt subsequent NAS messages based in part on the authentication protocol.

Abstract: Disclosed is a method for establishing an enhanced security context between a remote station and a serving network. In the method, the remote station forwards a first message to the serving network, wherein the first message includes an information element signaling that the remote station supports an enhanced security context. The remote station generates at least one session key, in accordance with the enhanced security context, using the information element. The remote station receives, in response to the first message, a second message having an indication that the serving network supports the enhanced security context. The remote station, in response to the second message, has wireless communications protected by the at least one session key.

Abstract: Se divulga un método para establecer un contexto de seguridad mejorada entre una estación remota y una red en servicio. En el método, la estación remota reenvía un primer mensaje a la red en servicio, en donde el primer mensaje incluye un elemento de información que señaliza que la estación remota soporta un contexto de seguridad mejorada. La estación remota genera al menos una clave de sesión, de acuerdo con el contexto de seguridad mejorada, utilizando el elemento de información. La estación remota recibe, en respuesta al primer mensaje, un segundo mensaje que tiene una indicación de que la red en servicio soporta el contexto de seguridad mejorada. La estación remota, en respuesta al segundo mensaje, tiene comunicaciones inalámbricas protegidas por dicha al menos una clave de sesión.
