Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a registration procedure with a mobility function of a 5G core network. Accordingly, the UE may derive a main key, associated with a trusted network gateway function, based on the registration procedure. The UE may further determine a root key based on the main key. The UE may derive a first pairwise master key (PMK), associated with a trusted network, from the root key. The UE may communicate with a first access point (AP) for the trusted network. The UE may further derive a second PMK, associated with the second AP, from the first PMK. Numerous other aspects are described.

Abstract: Methods, apparatuses, and computer-readable storage medium for encrypting discovery messages are provided. An example method at a first UE may include obtaining a discovery message that is ciphered based on at least one of a ciphering key, a ciphering algorithm, or a first set of time parameters, where the discovery message is scrambled based on at least one of a scrambling key, a scrambling algorithm, or a second set of time parameters. An example method may also include descrambling the discovery message based on at least one of the scrambling key, the scrambling algorithm, or the second set of time parameters. An example method may also include deciphering the discovery message based on at least one of the ciphering key, the ciphering algorithm, or the first set of time parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, from a second wireless communication device, a discovery message that includes a service code. The first wireless communication device may verify the service code. The first wireless communication device may transmit, to the second wireless communication device, a connection message that includes a protected service code that is derived from the service code. Numerous other aspects are described.

Abstract: Various aspects pertain to ways to securing a peer-to-peer communication link that serves to relay transmissions to/from a managed mobile network node. A first user equipment may identify a second user equipment that can communicate via a peer-to-peer wireless interface and serve as a relay between the first user equipment and a managed mobile network node. A relay session key material may be obtained from the managed mobile network node. A peer-to-peer communication link between the first user equipment and the second user equipment may be established or modified by, for example, securing the peer-to-peer communication link based on the relay session key material. A protocol data unit session may be established, over the peer-to-peer communication link, between the first user equipment and the managed mobile network node for secured transmissions there between.

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: Certain aspects of the present disclosure provide techniques for managing security keys for enciphering and deciphering packets transmitted in a wireless communications system. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes obtaining an indication of a key area identifier (ID) of a first cell node, wherein the key area ID identifies a set of cell nodes that are associated with a network node that uses a first key for enciphering or deciphering messages and communicating a first set of messages with the first cell node using the first key for enciphering or deciphering the first set of messages.

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: Creation or update of a security context between user equipment and MSC/VLR (Mobile Switching Centre/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.
