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: 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: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for configuring of a NAS COUNT value of a mapped EPS security context associated with an intersystem change of a UE from a 5G system to an EPS. The aspect includes generating, by a UE, a mapped EPS security context associated with an intersystem change of the UE from a 5G system to an EPS, wherein the mapped EPS security context comprises security parameters created based a 5G security context used for the 5G system, the security parameters enabling security-related communications between the UE and a network entity; determining an UL NAS COUNT value and the DL NAS COUNT value for the mapped EPS security context; and transmitting, by the UE, a NAS message to the network entity, the NAS message including the UL NAS COUNT value of the mapped EPS security context.

Abstract: A user device having a security context with a first network based on a first key may establish a security context with a second network. In a method, the user device may generate a key identifier based on the first key and a network identifier of the second network. The user device may forward the key identifier to the second network for forwarding to the first network by the second network to enable the first network to identify the first key at the first network. The user device may receive a key count from the second network. The key count may be associated with a second key forwarded to the second network from the first network. The user device may generate the second key based on the first key and the received key count thereby establishing a security context between the second network and the user device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a system parameter identified by a network entity (e.g., a public key generator (PKG)), and receive a cell identifier during a connection procedure between the UE and a base station in wireless communication with the UE. The cell identifier may be associated with the base station. The UE may encrypt at least a portion of a message associated with the connection procedure using the cell identifier and the system parameter. In some examples, the portion of the message may include private information. The UE may transmit the message to the base station as part of the connection procedure.

Abstract: A user equipment (UE) may receive system information from a base station and may calculate a hash value using the system information as input to a hashing function. Similarly, prior to transmitting the system information, a valid base station may calculate a hash value using the system information as input to a hashing function. The base station may transmit the calculated hash value (e.g., which represent or be included in a set of hash values) to the UE in an access stratum (AS) security mode command (SMC) message. The UE may determine whether the received system information was modified based on the hash value (e.g., by comparing the UE calculated hash value and the set of hash values received from the base station in the AS SMC). If the UE indicates a mismatch of hash information, the base station may re-transmit the system information (e.g., in an integrity protected message).

Abstract: The present disclosure provides techniques that may be applied, for example, in a multi-slice network for maintaining privacy when attempting to access the network. An exemplary method generally includes transmitting a registration request message to a serving network to register with the serving network; receiving a first confirmation message indicating a secure connection with the serving network has been established; transmitting, after receiving the first confirmation message, a secure message to the serving network comprising an indication of at least one configured network slice that the UE wants to communicate over, wherein the at least one configured network slice is associated with a privacy flag that is set; and receiving a second confirmation message from the serving network indicating that the UE is permitted to communicate over the at least one configured network slice.

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 methods 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: Creation or update of a security context between user equipment and MSC/VLR (Mobile Switching Center/Visitor Location Register) for circuit switched domain services is provided. The creation or update is based on conversion of the security context used in an evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the Mobility Management Entity (MME) to a security context for the circuit switched domain target system and transferring it to a MSC/VLR. When user equipment is moved from E-UTRAN to GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network (GERAN/UTRAN), a MME does not need to perform authentication and key agreement procedures to establish shared circuit switched security context for the user equipment.
