Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). A method performed by a user equipment (UE) in a wireless network, the method comprising: establishing a communication with an application function (AF) server using a first authentication and key management for applications (AKMA) application key (K); receiving a message over the established communication from the AF server, the message indicating that a lifetime of the first Khas expired; and configuring a back-off flag in the UE to optimize an AKMA key refresh mechanism in the wireless network in response to receiving the message, wherein the back-off flag prevents a request for a first AKMA anchor key (K) until a fresh primary authentication is performed.
