Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE).
The present disclosure provides a system and method for security protocol implemented in a communication network. The method performed by a first network entity includes determining based on a HUB being in a trusted area or in a non-trusted area, whether one or more network functions (NFs) are configured to perform security operations based on a generation of a message by a corresponding one or more NFs. Determining, based on a result of the determination that one or more NFs are not configured to perform the security operation, one or more network entities that are configured to perform the security operation, wherein the one or more network entities comprises at least one of the HUB, a Central Unit User Plane (CU-UP), and a Distributed Unit (DU), wherein a plurality of security keys are generated by the determined one or more network entities, and wherein the generated plurality of security keys is shared with a user equipment (UE).
