Open Security Issues for Edge Named Function Environments

In this article, we focus on in-network function execution in information-centric networking (ICN), and we highlight the open issues for secure distributed computing given an ICN substrate. Within such an ICN-based ecosystem, we present an exemplary use case from the autonomous automotive IoT area, namely, localized sensing. Based on this use case, we identify security challenges, discuss the different options to tackle these challenges, and provide directions for future work.
