1. A method performed by an Integrated Access and Backhaul (IAB)-donor node for authentication of an IAB node in a wireless network, the method comprising:
receiving, from the IAB node, a request for one or more Internet Protocol (IP) addresses via Radio Resource Control (RRC);
sending, to the IAB node, an IP address of a Distributed Unit (DU) of the IAB node to identify security context information of the IAB node;
identifying the security context information of the IAB node based on the IP address of the DU of the IAB node;
generating a security parameter, based on the security context information of the IAB node; and
establishing an Internet Protocol Security (IPsec) Security Association (SA) with the IAB node, based on the generated security parameter,
wherein the security parameter is used as Pre-shared Key (PSK) for Internet Key Exchange (IKEv2), authentication.
