1. A method of a user equipment (UE) in a wireless communication system supporting an integrated access and backhaul (IAB) communication, the method comprising:
performing, based on a security configuration, a first security processing operation for a packet data convergence protocol (PDCP) layer in accordance with a communication with an IAB node, wherein the communication comprises a data transmission and a data reception with the IAB node;
receiving, from the IAB node, a first control message including security configuration information and information associated with a reconfiguration time duration;
within the reconfiguration time duration, updating the security configuration for the PDCP layer based on the security configuration information; and
after the reconfiguration time duration, performing, based on the updated security configuration, a second security processing operation on the data transmission and the data reception with the IAB node.
