VOSYSmonitor, a Low Latency Monitor Layer for Mixed-Criticality Systems on ARMv8-A

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.
