    Abstract: A system and a method of counter management and security key update for device-to-device (D2D) communication are provided. The method includes creating by a user equipment, a new packet data convergence protocol (PDCP) entity for a service group wherein a service group is identified by a destination identifier (ID), determining if any PDCP entity of the service group exists or not, generating a new proximity service (ProSe)traffic key (PTK) from a ProSe group key (PGK) corresponding to the service group associated with the new PDCP entity, initializing a new packet counter associated with the service group to zero if the new PDCP entity is a first PDCP entity associated with the service group, generating a ProSe encryption key (PEK) from the PTK and encrypting data packets mapped to the new PDCP entity using the PEK and a packet counter associated with the service group.

    Abstract translation: 提供了一种用于设备到设备（D2D）通信的计数器管理和安全密钥更新的系统和方法。 该方法包括由用户设备创建用于服务组的新的分组数据会聚协议（PDCP）实体，其中服务组由目的地标识符（ID）标识，确定服务组的任何PDCP实体是否存在， 从与新的PDCP实体相关联的服务组对应的ProSe组密钥（PGK）生成新的邻近业务（ProSe）业务密钥（PTK），如果新的PDCP实体初始化与业务组关联的新的分组计数器为零 是与服务组相关联的第一PDCP实体，从PTK生成ProSe加密密钥（PEK），并使用PEK和与服务组相关联的分组计数器加密映射到新PDCP实体的数据分组。

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a method and system for authentication method selection in an edge network system. The method includes determining whether the UE is configured with authentication methods supported by at least one of an ECS, an EES, a home network and a serving network in the edge network system. The method further includes selecting the authentication methods configured at the UE based on a capability of the UE to establish a connection with the EES based on the at least one selected authentication method when the UE is configured with the authentication methods supported by at least one of the ECS, the EES, the home network and the serving network.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed herein is method and system for authorizing a MCX server. An authorization server is configured to receive a validation request from a MCData message store in response to a user account access request received by MCData message store from MCX server. Further, authorization server is configured to validate identification information of MCX server. Further, authorization server is configured to transmit a validation response to MCData message store indicating authorization of MCX server to access user account in MCData message store, upon successful validation of identification information of tMCX server. An authorization server is introduced to provide additional layer of security to user account with MC Data.

    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.

    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. 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 are provided. 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. The method for mitigating DOS attacks in wireless networks includes requesting a public land mobile network for accessing a non-public network (NPN) through a CAG cell, verifying the permissions of a UE to access the requested NPN through the CAG cell, and performing a primary authentication.
