Abstract
Methods, systems, and devices for wireless communications enable establishment of secure communications and security keys for a remote user equipment (UE) and a relay UE to perform relayed sidelink communications in which the remote UE communicates with a network via the relay UE. To establish secure communications for the direct communications between the relay UE and the remote UE, one or more security keys are used for encryption and decryption of communications. To establish the security keys, the relay UE forwards a request for direct communications to a key management function (e.g., a ProSe key management function (PKMF)) in a control plane of a core network (e.g., in a control plane message to the PKMF via an access and mobility function (AMF)). The PKMF derives relay keys and return information related to the relay keys to the relay UE the remote UE.
