A security and trust framework for virtualized networks and software-defined networking

TLDR

5G networks are emerging as the next generation of mobile telecommunications, building on the successes of 2G, 3G, and 4G technologies. The study identifies open research issues in 5G security and trust within virtualized and software‑defined networking environments and proposes a comprehensive framework to address them. The framework employs adaptive trust evaluation, sustainable trusted‑computing techniques, and cloud‑based deployment of secure services to ensure platform trust and software‑defined network security. Analysis shows the framework meets all standardized security requirements and offers practical deployment advantages, while outlining future research directions. © 2015 John Wiley & Sons, Ltd.

Abstract

With the great success of the second-generation wireless telephone technology and the third-generation mobile telecommunications technology, and the fast development of the fourth-generation mobile telecommunications technology, the phase of fifth-generation mobile networks or fifth-generation wireless systems 5G is coming. In this article, we indicate the open research issues of 5G security and trust in the context of virtualized networking and software-defined networking. We further propose a framework of security and trust focusing on solving 5G network security issues. The proposed framework applies adaptive trust evaluation and management technologies and sustainable trusted computing technologies to ensure computing platform trust and achieve software-defined network security. It adopts cloud computing to securely deploy various trustworthy security services over the virtualized networks. We analyze that the framework can support and satisfy all security requirements specified in standardization. We also suggest future research work according to the proposed framework and discuss the advantages of our framework in terms of practical deployment. Copyright © 2015 John Wiley & Sons, Ltd.
