Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a relay UE, a first message comprising a first freshness parameter, an identity of the UE, and authentication information, where the authentication information is used by a network node to authenticate the UE with security context information of the UE. The UE may derive a relay key for security establishment between the UE and the relay UE based on the first freshness parameter, a set of key generation parameters, and a shared key with the network node. The UE may derive a relay session key for security establishment between the UE and the relay UE based on the relay key, a first nonce of the UE, and a second nonce of the relay UE. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for sidelink discovery are provided. An example method may include transmitting, to a first network entity from a first public land mobile network (PLMN) associated with the UE, a discovery request. The example method may further include receiving, from the first network entity from the first PLMN, a discovery response including security information generated by a second network entity from a second PLMN associated with the UE. The example method may further include communicating a sidelink message based on the security information generated by the second PLMN.

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: 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.
