Abstract
The emergence of edge computing and the Internet of Things (IoT) is primarily concerned with security, IoT applications are migrating to edge devices. As a result, potential risks are rising and IoT edge device data access is turning into a serious issue. The IoT devices security is intrinsically reliant on the internal hardware and software building block that the application has access to. If any of the device's essential parts are not included in secure system architecture, they are destined to fail and open the door to malicious activity by system entry, and unauthorized access. Therefore, comprehensive end-to-end solutions are required to safeguard the system from these kinds of threats. In this paper, we propose a novel resource-constrained lightweight security architecture with three security parameters namely secure Boot, Firmware Over the Air(FOTA), and secure key storage. The proposed architecture is more suited for resource-constrained edge devices since it is implemented with less overhead and memory footprint than other proposed architectures in the literature. Our architecture is 20% more efficient compared to other architectures.
