    Abstract: Aspects of security schemes (e.g., integrity protection, encryption, or both) are described. A measure of access stratum security can be realized without overhead associated with establishing and/or maintaining the per-cellular-device access stratum security context at a Cellular Internet of Things (CIoT) base station (C-BS). A gateway (e.g., a CIoT Serving Gateway Node (C-SGN)) may derive a first key. The first key may be only known to the C-SGN. The C-SGN may derive a second key from the first key and a parameter unique to the C-BS. The C-SGN may also derive a third key from the second key and an identity of a cellular device. The C-SGN may send the second and third keys to the C-BS and cellular device, respectively. Small data messages encrypted and/or integrity protected by the cellular device may be decrypted and/or verified by the C-BS.

    Abstract: A device that identifies entry into a new service area, transmits a service area update request to a network device associated with a network, receives a control plane message from the network indicating control plane device relocation or a key refresh due to a service area change in response to transmitting the service area update request, and derives a first key based in part on data included in the control plane message and a second key shared between the device and a key management device. Another device that receives a handover command from a network device associated with a network, the handover command indicating a new service area, derives a first key based on data included in the handover command and on a second key shared between the device and a key management device, and sends a handover confirmation message that is secured based on the first key.

    Abstract: A particular method includes receiving, at a secure user plane location (SUPL) server, an indication from a mobile device of one or more transport layer security (TLS) cipher suites supported by the mobile device; determining whether the one or more TLS cipher suites include a TLS pre-shared key (TLS-PSK) cipher suite that is supported by the SUPL server; in response to determining whether the one or more TLS cipher suites include the TLS-PSK cipher suite that is supported by the SUPL server, performing a generic bootstrapping architecture (GBA)-based authentication process to authenticate the mobile device, or determining whether the SUPL server supports a certificate-based authentication method; and in response to determining that the SUPL server supports the certificate-based authentication method, performing the certificate-based authentication method that includes sending a server certificate to the mobile device and receiving a device certificate from the mobile device.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment may establish a sidelink unicast link with a remote UE via a sidelink signaling interface; receive, from a network entity, configuration information comprising at least one of: remote UE link identifier information associated with the sidelink unicast link for a relay service, an RLC channel mapping between the one or more RLC channels of the sidelink unicast link and the link with the network entity, or data routing information associated with the relay service; configure the one or more RLC channels for the sidelink unicast link and the link with the network entity based at least in part on the configuration information; and relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are provided.

    Abstract: Embodiments include devices and methods for providing secure communications between a first computing device and a second computing device are disclosed. A processor of the first computing device may determine in a first application software first security key establishment information. The processor may provide the first security key establishment information to a communication layer of the first computing device for transmission to the second computing device. The processor may receive, in the first application software from the communication layer of the first computing device, second security key establishment information received from the second computing device. The processor may determine a first security key by the first application software based at least in part on the second security key establishment information. The processor may provide the first security key to the communication layer for protecting messages from the first application software to the second computing device.
