The Fifth Generation (5G) mobile networks promise faster connectivity and futuristic applications and services. In order to meet the high expectations, 5G joins forces with virtualization technologies like Network Functions Virtualization (NFV) and adopts cloud-native solutions. At the same time, it relies on shifting the computation to the network edge for offloading computing power, local caching, minimized latency and flexibility in the deployment. However, new opportunities unlock new security challenges. Man-in-the-middle, denial-ofservice attacks and tampering are now becoming easier because of the scattered devices and their varying locations. Meanwhile, the dynamic nature of the cloud raises the need for on-time threats prevention.In this work, we propose a way to answer the new challenges by bringing trust into the virtualized edge infrastructure. We present our contributions to the development of security services for platform authentication and integrity, hosted inside a trusted execution environment (TEE). We also evaluate the performance overhead of our work and suggest future improvements.

In recent years, there is an ongoing computational shift from the data center to the network edge. Due to the increased hardware capabilities of devices, the edge can also benefit from the dynamic and scalable services provided by the virtualization technologies. In turn, the edge computing brings low-latency and reduced network traffic, location-awareness and local caching. However, the new capabilities unlock new challenges in terms of security, data and workload location.In this work, we focus on the threats caused by the heterogeneous and distributed nature of the edge infrastructure. We build a trusted edge based on the hardware isolation of ARM TrustZone. Moreover, we use it as a secure foundation to perform location-aware virtual machine deployment utilizing the dispersed nature of the infrastructure. We measure the performance of our solution and discuss the overall overhead and potential improvements.
