Security and Resilience in 5G: Current Challenges and Future Directions.

5G tends to be a multi-layered, multi-actor, and multi-access mobile network in order to fulfill the stringent availability, security, privacy and resilience requirements that are usually contradictory. In this paper, we propose a 5G vision based on softwarization. We provide a non-exhaustive list of current security, trust and resilience issues that are critical to be explored in 5G. We finally give some directions to overcome these issues.
