- Abstract
- Challenges of securing 5G networks have more complex security vulnerabilities due to a large number of connected devices and services. To provide access to private networks using the public 5G architecture, the use of virtual private network (VPN) techniques is commonly employed to address 5G security issues. However, the VPN protocol is vulnerable in that it can protect unauthorized nodes as authentication is done only after the connection. We propose a secure 5G architecture that utilizes the software-defined perimeter (SDP) to authenticate and then grant access to 5G devices based on specific criteria for direct trust access to private networks. We also show the communication flow of direct trust access to a private network through a public 5G architecture using the VPN technique and a direct trust access server (DTAS).
