    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) in a wireless communication system according to an embodiment of the present disclosure comprises: receiving, from a relay user equipment (UE) for a UE-network relay communication, a relay key request message including an identifier of a remote UE for the UE-network relay communication; identifying whether the relay UE is authorized to provide a UE-network relay service; identifying an authentication server function (AUSF) related to the remote UE, based on the identifier of the remote UE; transmitting, to the AUSF, an authentication request message including the identifier of the remote UE; in case that an authentication procedure for the remote UE based on the identifier of the remote UE is successfully performed, acquiring a proximity-based services (ProSe) session encryption key established between the remote UE and the relay UE; and transmitting, to the relay UE, the ProSe session encryption key.
