Abstract

Both Long-Term Evolution (LTE) and Long-Term Evolution Advanced (LTE-A) technologies have been designed to provide fourth-generation telecommunications and high-speed broadband Internet access,   although it was LTE-A that ultimately supported the requirements for the fourth generation of                 telecommunication systems, and is accepted as the 4G. The specifications for 4G networks were released over the years by 3rd Generation Partnership Project (3GPP). The main objective for the 4G network is providing IP-based capabilities such as high network speed, high network capacity, and voice and data  support through unifying the existing mobile networks and creating a central and global IP-based network. Due to the unique features of the LTE networks, there exist new challenges in designing their network mechanisms, which have consequently resulted in network security vulnerabilities. This article is the result of years of research on LTE network and its security and vulnerability analysis, as well as the feasibility of localizing the network security based on the standard platform. In this article, initially an overview of the LTE/SEA system structure is provided, and the sectors involved with network security are outlined. Then, the authentication process, protocols setup, and key agreement between different sectors of the network are described and analyzed specifically for LTE networks. Afterwards, considering the significance of specific key management in this type of network, its advantages and disadvantages are examined. Furthermore,  security pathology of this network is described with a comprehensive outlook and finally, the feasibility of LTE network localization based on the standard platform is investigated. The localization results presented as a table at the end of the article are obtained through 3GPP standards analysis, investigation of all    common protocols for different sectors of the network, and the feasibility study of localization capacity while maintaining compliance with the standard. This table is crucial in terms of network security, and demonstrates the localization capacities within the network structure accurately.
