Title:
A comprehensive and lightweight security architecture to secure the IoT throughout the lifecycle of a device based on HIMMO
Authors: Oscar Garcia-Morchon, Ronald Rietman, Sahil Sharma, Ludo Tolhuizen, Jose Luis Torre-Arce
Abstract:Smart objects are devices with computational and communication capabilities connected to the Internet forming the so called Internet of Things (IoT). The IoT enables many applications, for instance outdoor lighting control, smart energy and water management, or environmental sensing in a smart city environment. Security in such scenarios remains an open challenge due to the resource-constrained nature of devices and networks or the multiple ways in which opponents can attack the system during the lifecycle of a smart object.This paper firstly reviews security and operational goals in an IoT scenario inspired in a smart city environment. Then, we present a comprehensive and lightweight security architecture to secure the IoT throughout the lifecycle of a device. Our solution relies on the lightweight HIMMO scheme as the building stone and shows how HIMMO is not only efficient resource-wise, but that it enables advanced IoT protocols and deployments. Our design and analysis show that our HIMMO-based security architecture can be easily integrated in existing communication protocols such as IEEE 802.15.4 or OMA LWM2M providing a number of advantages that existing solutions cannot provide both performance and operation-wise.
