    Abstract: Accordingly, embodiments herein provide a system for managing anti-steering of roaming in a wireless communication network. The system includes a HPLMN, a VPLMN and a UE. The HPLMN obtains a register request message from the VPLMN and derives at least one HPLMN specific security key based on at least one security parameter. Further, the HPLMN protects a preferred PLMN list using the at least one HPLMN specific security key and the security parameter and sends the protected preferred PLMN list to the VPLMN along with necessary security information. Further, the VPLMN is configured to receive the protected preferred PLMN list from the HPLMN and send a message including the protected preferred PLMN list to the UE. The message mandates the VPLMN to send the preferred PLMN list transparently to the UE. Further, the UE is configured to receive the message including the preferred PLMN list from the VPLMN.

    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). Methods, network entities, and systems for mitigating Denial of Service (DoS) attack in a wireless network (e.g., access network (AN), core network (CN)). Embodiments herein disclose methods and systems for mitigating Denial of Service (DOS) attacks in wireless networks, by performing admission control by verifying a User Equipment's (UE's) registration request via a Closed Access Group (CAG) cell without performing a primary authentication. Embodiments herein disclose methods and system for verifying permissions of the UE to access a CAG cell based on the UE's Subscription identifier, before performing the primary authentication. Methods and systems for mitigating Denial of Service (DoS) attack in a wireless network. A method for mitigating Denial of Service (DOS) attacks in wireless networks includes requesting a public land mobile network (PLMN) for accessing a non-public network (NPN) through a Closed Access Group (CAG) cell, verifying the permissions of a user equipment (UE) to access the requested NPN through the CAG cell, and performing a primary authentication.

    Abstract: A method and system for authenticating application program interface (API) invokers using a common application program interface framework (CAPIF) is provided. 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: 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). Embodiments herein provide method and system for end-to-end security over signaling plane in a mission critical data (MCData) communication system. The proposed method includes various ways of securing MCData data payload transmitted over signaling plane using short data service (SDS). The proposed method allows usage of multiple security keys to encrypt the MCData SDS message as per the requirements. Various Keys such as, signaling plane key or media plane key or a dedicated MCData data payload signaling key can be used independently or in a combination thereof to achieve the desired security context. The proposed method allows protection of all the application level components with the signaling plane security context.

Further, the method includes generating, by a source User Equipment (UE), a D2D Media Access Control (MAC) Protocol Data Unit (PDU) comprising a unicast parameter. Further, the method includes transmitting, by the source UE, the D2D MAC PDU to the destination UE. Further, the method includes receiving, by the destination UE, the D2D MAC PDU. Further, the method includes detecting, by the destination UE, one of unicast parameters and groupcast parameters of the D2D MAC PDU. Furthermore, the method includes identifying, by the UE, the D2D MAC PDU is for one of the unicast D2D communication when the unicast parameters are detected, and the groupcast D2D communication when the groupcast parameters are detected.
