Abstract
MEC technology provides a distributed computing environment in 5G mobile networks for application and service hosting. It allows customers with different requirements and professional competencies to use the services offered by external suppliers. We consider a service access control framework on 5G MEC networks that is efficient, flexible, and user-friendly. Its central element is the MEC Enabler, which handles AAA requests for stakeholders accessing services hosted on the edge servers. The JSON Web Token (JWT) open standard is a suitable tool for the MEC Enabler to manage access control credentials and transfer them securely between parties. In this paper, in the context of access control, we propose the token reference pattern called JSON MEC Access Token (JMAT) and analyze the effectiveness of its available protection methods in compliance with the standard requirements of MEC-hosted services in 5G networks.
Highlights
A new version of the mobile network has been created, namely 5G MEC [3,4]. It ensured the development of narrowly specialized web services and led to the concept of 5G MEC vertical industries, i.e., web service packages implemented in mobile networks and tailored to the requirements of different sectors of the economy [5]
Analysis of our work shows that using JavaScript Object Notation (JSON) MEC Access Token (JMAT), it is possible to achieve a good time for token validation, even with a single CPU thread and python instructions
Realizing services based on the 5G MEC paradigm will impressively improve data transmission quality and network efficiency compared to a typical 5G mobile network
Summary
The basic features that characterize 5G networks are the quality requirements for communication: high throughput, low latency, high device density, and high network reliability and availability, see [1]. These properties allow for the implementation of many network services previously unavailable in mobile networks. A new version of the mobile network has been created, namely 5G MEC [3,4] It ensured the development of narrowly specialized web services and led to the concept of 5G MEC vertical industries, i.e., web service packages implemented in mobile networks and tailored to the requirements of different sectors of the economy [5]
