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 (KAF); receiving a message over the established communication from the AF server, the message indicating that a lifetime of the first KAF has 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 (KAKMA) until a fresh primary authentication is performed.

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). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments herein provide a method of enabling authentication and key management application (AKMA) services in roaming mode comprising generating a key associated with the AKMA services after a primary authentication of the UE with a wireless network; determining whether to share the at least one key associated with the AKMA services with a visited AKMA anchor function (vAAnF); and sharing the at least one key associated with the AKMA services with the vAAnF.
