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.

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. Embodiments herein provide a method for determining whether a base station is genuine or rouge in a wireless network. If a received authentication key matches with the authentication key generated in the UE, the method includes identifying a base station as genuine base station and carrying out a normal procedure. If the received authentication key does not match with the generated authentication key, the method includes identifying the base station as a rouge base station. The authentication key can be a digital signature (DS), a Message Authentication Code-Integrity (MAC-I), and a hash of MIB/SIBs including PCI.

Embodiments herein disclose methods for establishing secure communication in a wireless communication network (3000) by an AUSF entity (400). The method includes receiving a key request message from a remote UE (100a) through an AMF entity (500). Further, the method includes acquiring one of the SUPI of the remote UE (100a) and a REAR ID associated with the SUPI of the remote UE (100a). Further, the method includes generating a rear key for remote UE (100a) communication via a UE-to-network relay. The REAR key is used for deriving a first ProSe key. Further, the method includes sending a key response message to the remote UE (100a) for establishing secure communication, where the key response message includes the generated REAR key, the REAR ID and at least one of a relay UE ID and a temporary ID of a relay.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate.
A method of detecting cyber-attacks using network analytics in a user equipment (UE) is provided. The method includes receiving, by a network data analytics function (NWDAF), a request for sharing analytics information associated with the UE from a consumer network function (NF), requesting the analytics information associated with the UE and causing the cyber-attack to at least one 5th generation core (5GC) network entity, receiving the analytics information associated with the UE and causing the cyber-attack from the at least one 5GC network entity, comparing an expected behavior of the UE with an actual behavior based on the analytics information provided by the at least one 5GC network entity, deriving analytics associated with the cyber-attack based on the analytics information and the comparison, and sending the analytics associated with the UE to the consumer NF.
