Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein is to provide a method for providing user consent for UE in a 5G network (1000) by a UE (300). The method includes receiving a request message from a network apparatus (200) to check with the UE (300) whether the network apparatus (200) can provide subscribed event information to a NWDAF (100). The request message includes the subscribed event information and a consumer NF ID to obtain consent from the UE (300). Further, the method includes determining, by the UE (300), using the preconfigured data whether a consent can be provided for the subscribed event information to the NWDAF (100). Further, the method includes sending, by the UE (300), a response message to the network apparatus (200), wherein the response message comprises a consent indication allowing the network apparatus (200) to provide the subscribed event information to the NWDAF (100).

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 method includes comparing plurality of parameters (e.g. TAI) received in message (e.g. initial NAS message, registration request, first protected NAS message) from UE and plurality of parameters (e.g. TAI) broadcasted/received/stored by AMF entity and/or genuine gNB. AMF entity and/or genuine gNB sends an accept message (e.g. NAS accept) or reject message (e.g. NAS reject, RRC reject or RRC reconfiguration.) with appropriate error cause value to UE to mitigate the MitM attack. Based on received message from AMF entity and/or genuine gNB, UE detects that UE is camped on genuine gNB or fake gNB. UE performs action(s) (e.g. cell reselection), when UE is camped on fake gNB/eNB to mitigate MitM attack.

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. Methods and systems for generating/deriving CU-UP security keys for disaggregated gNB architecture are described herein. A UE/gNB can inform the gNB/UE about the capability of the UE/gNB to derive CU-UP security keys. CU-UP security keys comprise an integrity protection key and a ciphering key. The gNB derives an integrity protection key and a ciphering key upon determining that the UE supports derivation of the CU-UP security keys or the UE has capability to derive CU-UP security keys. The integrity protection key protects the integrity of data, in a DRB, traversing through a CU-UP. The ciphering key encrypts the data, in the DRB, traversing through the CU-UP. The gNB sends RRC connection reconfiguration messages, which include multiple parameters. The UE derives an integrity protection key and a ciphering key, for each DRB, based on the plurality of parameters, for protecting the integrity of the data and encrypting the data.

Abstract: The present disclosure relates to a pre-5G or 5G communication system to support higher data rates beyond 4G communication system such as LTE. The present disclosure enables the 3GPP system to protect the broadcasted unique UAV identities for a secured UAV communication. In remote identification process, the UAVs send the messages with flight information to the receiving party (i.e., UTM/USS, a TPAE or another UAV). Also, there are use cases on local broadcast of UAV identities for remote identification and tracking purposes. The present disclosure renders a mechanism that only the authorized personnel is able to decode the received broadcasting ID from the initiating UAV. The present disclosure protects unique UAV identities broadcasted so that, the fake UAV or unauthorized personnel cannot use the broadcasted ID for certain attacks such as impersonation of genuine UAV, tracking of the UAV and so on.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Method and system for supporting protection of MBS traffic in wireless network. Embodiments herein disclose a method and a system for supporting protection of Multi-cast Broadcast Service (MBS) traffic in a wireless network. The method includes receiving security information in a MBS announcement by user equipment (UE) (100). The method includes determining if MBS traffic protection is applied or not over the service layer; determining whether security capability of the MBS supports handling of the MBS traffic protected at the service layer, when the MBS traffic protection is applied over the service layer; joining a MBS session by sending a Non-access stratum (NAS) request message to a session management function (SMF) device (200), and requesting for the 5GC individual traffic delivery method by including an indication in the NAS request message, if the security capability of the MBS does not support handling of the MBS traffic protected at the service layer; and receiving the MBS traffic via 5GC individual traffic delivery method.
