Device-to-Device (D2D) communications will be used as an underlay technology in the Fifth Generation mobile network (5G), which will make network services of multiple Service Providers (SP) available anywhere. The end users will be allowed to access and share services using their User Equipments (UEs), and thus they will require seamless and secured connectivity. At the same time, Mobile Network Operators (MNOs) will use the UE to offload traffic and push contents closer to users relying on D2D communications network. This raises security concerns at different levels of the system architecture and highlights the need for robust authentication and authorization mechanisms to provide secure services access and sharing between D2D users.
- Investigated D2D Communication applications and security issues.
- Introduced a network services abstraction and suggests the mapping of existing studies with the network service abstraction which can be used in the harnessing the development and implementation of D2D communication applications in 5G network.
- 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.
- Proposed a D2D level security solution to provide security for access, caching and sharing data in network-assisted and non-network-assisted D2D communications scenarios.
