Overview: Security in 5G Wireless Systems

Abstract:

Wireless systems have evolved and are becoming increasingly important because of their capacity and flexibility to support new services and technologies such as enhanced mobile broadband (eMBB), massive machine type communications (mMTC), massive internet of things (mIoT) and ultra-reliable low latency communications (URLLC). This paper presents a systematic review of the status of the fifth-generation or 5G wireless system, addresses its physical architecture as well as the service-based architecture. The main elements of network slicing as a different vision of 5G, in response to the need to split the physical network into multiple logical networks to serve various types of services based on different requirements. Software-defined networking (SDN) and network functions virtualization (NFV) are also presented as tools needed for network resource management. The main security challenges of 5G networks are analyzed and possible solutions are discussed. A comparative analysis is presented of 5G versus its 4G predecessor.
