Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for securing unicast message communication is provided. The method includes sending, by a user equipment (UE), a request-message for resuming radio resource control (RRC) connection to a base station, wherein the request message comprises a first-parameter defining “resume cause”. A response pertaining to at least one of network-release or network-resumption is received by the UE, wherein the response comprises a second parameter defining “resume cause”. Based on a successful-mapping between the first parameter and the second parameter, the response is acknowledged by the UE. However, for example, in case of network-rejection of the request due to network congestion, an RRC reject message comprising a first message authentication code is computed by the base station based on a stored network security context and communicated to the UE. Thereafter, a second message authentication code is mapped by the UE with the first message authentication code.

The method includes establishing by a CAPIF core function (CCF) a secure Transport Layers Security (TLS) connection with at least one API invoker, on receiving a connection request from the at least one API invoker to access at least one service API on a CAPIF-2e interface. Further, the method includes determining by the CCF at least one security method to be used by the at least one API invoker for a CAPIF-2e interface security (C2eIS) of the at least one API invoker for accessing the at least one service API on a CAPIF-2e interface. The method further includes enabling the C2eIS by an API exposing function (AEF) the at least one API invoker based on the determined at least one security method.

Abstract: Accordingly, embodiments herein disclose a method for handling a closed access group (CAG) related procedure in a wireless communication system. A network may receive a radio resource control (RRC) resume request message from a user equipment (UE). The network may determine whether the at least one CAG identifier (ID) broadcasted in a CAG cell is included in an allowed CAG list of the UE (100) in response to the RRC resume request message. The network may proceed with a RRC resume procedure in response to determining that the at least one CAG ID is included in the allowed CAG list.
