Abstract

Due to the increasing data traffic in mobile network, fifth generation (5G) will use Device to Device (D2D) communications as the underlay technology to offload traffic from the 5G core network (5GC) and push content to the edge closer to the users by taking advantage of proximity and storage features of User Equipment (UE). This will be supported by Networks Services (NS) provided by 5G, it will also enable new use cases that will provide the accessibility to other services in the Home network (HN) and third-party service provider (SP). Mobile Network Operators (MNO) will use NS such as D2D communications and content-centric networking (CCN) to deliver content-based services efficiently to UE. Both D2D and CCN have known security issues and their integration brings new security challenges. In this article, we present an integrated network service delivery (NSD) framework for 5G enabled D2D communications that leverages on NS for service discovery, content delivery, and protection of data. We also present a comprehensive investigation of security and privacy in D2D communications and service-oriented network, highlighting the vulnerabilities and threats on the network. We also evaluate the security requirements of NSD to deliver NS securely to D2D users based on X.805 security framework using the eight security dimensions and level abstraction approach for a systematic and comprehensive approach. Finally, we recommend security solution approaches for the secure NS access and sharing of data between users in 5G enabled D2D communications network.
