Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a system and method for key refresh in Authentication and Key Management for Applications (AKMA). The proposed method is to support Krefresh by requesting the refreshing parameters from the network once the Kis about to expire. Further, the proposed method is to support Krefresh by requesting the refreshing parameters from the network once the Kis about to expire. Further, the proposed method is used to support a mechanism to address the Key synchronisation issue at a User Equipment (UE) side, an Application Function (AF) side and at an AAnF using a key index included as a part of AKMA key identifier (A-KID). Further the proposed method uses certain mechanisms to provide the refresh parameter to the AUSF, the AAnF and the UE as a part of AKMA Refresh procedure or as a part of UPU procedure. Further, the proposed method supports AKMA key refresh with limited impacts on AKMA services in 5G system.
