Abstract: Certain aspects of the present disclosure provide techniques for access stratum level security of medium access control (MAC) transport blocks (TBs). A method for wireless communications includes generating a unique ciphering sequence number for each MAC TB of a plurality of MAC TBs. The method includes encrypting each of the plurality of MAC TBs based, in part, on the unique ciphering sequence number for each of the plurality of MAC TBs.

Abstract: An apparatus, method and computer-readable media are disclosed for performing wireless communications. For example, a process for securely accessing a service, can include: receiving, by a security service from a service, a request for a service key for accessing the service, the request for the service key including an indication to use a user plane security anchor (UPSA); transmitting, from the security service in response to the request for the service key, a service key response including the service key; receiving an indication for a UPSA key, the indication including an identifier for a UPSA for the service; generating the UPSA key based on the identifier for the UPSA; and transmitting the generated UPSA key to the UPSA for establishing a user plane security context between the UPSA and a wireless device.

Abstract: Thus, aspects of the present disclosure allow for a target UE to utilize a cooperative device to communicate with a base station when the target UE is out of coverage or in poor radio connections, but can still connect to another UE over a non-3GPP technology. Aspects of the present disclosure may receive a derived radio resource control (RRC) key from a user equipment (UE) in a non-Third Generation Partnership Project (non-3GPP) link between the apparatus and the UE. In some aspects, the UE is out of coverage of a network entity in a 3GPP link with the apparatus. In another instance, aspects of the present disclosure may receive control data from the network entity in the 3GPP link using the derived RRC key. In yet another instance, aspects of the present disclosure may transmit the control data to the UE in the non-3GPP link.

Abstract: Disclosed are methods and systems for providing home network routing information (HNRI) of remote user equipment (UE) following authentication failure, e.g., during establishment of UE-to-network (U2N) relay communication. In some aspects, a first UE may detect an authentication failure during establishment of a secure connection with a second UE, and in response to detecting the authentication failure, notifies the second UE of the authentication failure. In addition, the HNRI of a first authentication node within the home network of the first UE is provided to a second authentication node within the home network of the second UE, either by the first UE, by the second UE, or from being stored by the second authentication node from a previous interaction involving the first UE.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for protocol stacks and bearer modeling for assisted Uu connectivity. A UE and a PN may each establish a first connection with an AN and, based on the first connections with the AN, establish a second connection with each other. Based on a bearer configuration, the UE may determine whether to route data to the PN via the first connection with the AN or directly to the PN via the second connection with the PN. Accordingly, the UE may transmit the data to at least one of the AN or the PN based on the determination of whether to route the data to the PN via the first connection with the AN or directly to the PN via the second connection with the PN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may register to a cellular network associated with a multicast/broadcast multimedia service (MBMS). The UE may transmit, to the cellular network, a request to join the MBMS. The UE may receive, from the cellular network and based at least in part on being registered with the cellular network, a response that indicates an MBMS service key (MSK) and MSK identifier pair. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide for a security model for enabling multiple connectivity and service contexts while sharing a single connectivity context to establish a network connection. A context (e.g., connectivity context, service context, security context) is a set of information describing the connectivity, service, or security established between two or more entities. The connectivity context and service context may be established at different network nodes or entities. In one aspect of the disclosure, a connectivity context includes an Evolved Packet System (EPS) Mobility Management (EMM) context or both an EMM context and an EPS Session Management (ESM) context.

Abstract: Apparatus, methods, and computer-readable media for facilitating self-managed trust in Internet-of-Things networks are disclosed herein. An example method of trust management at a network manager includes enrolling a network endpoint with a network managed by the network manager. The example method also includes receiving trusted reference information for the network endpoint based on enrolling the network endpoint. Additionally, the example method includes performing verification of the network endpoint based on at least one of the trusted reference information or an attestation received from the network endpoint. Further, the example method includes enforcing policies to the network endpoint based on a result of the verification. Such trust management may improve privacy and security at the network, as well as reduce latency in responding to trust incidents.

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.
