Comparative Study of Security Architecture of 5G with 4G

Abstract

This paper presents the comparative study of security architecture of 5G and 4G. Since 5G is a new technology and represents a revolution in network technology, security issues still surround it. When it first emerged during the planning and development of technology, 5G security was the major emphasis. The key factors driving the development of 5G, according to developers worldwide, are the technology's essential characteristics for 5G security: communication, privacy, security, resilience, and identity management.

Base stations are not visible to terminals at the IP layer in the 4G architecture that we are working with. A terminal will send an IP packet to the gateway that connects to all base stations whenever it sends one. Only layer 2 packets between terminals and the gateway are relayed by base stations.

The security elements of this system are designed using fundamental design principles and a risk-based attitude on the part of the developers. Network slicing is the element that is crucial to the development of 5G technology.

With the support of network slicing, virtualization, and cloud-based resources, the 5G security network architecture offers noteworthy high-performance advantages and supports a variety of applications. These benefits will aid organisations in defending against surface assaults and rising security concerns.

In this paper, we have studied the 5G network,4G network and its architecture from a security point of view. Also, study 5G security, 4G security and how 5G is more secure.
