Abstract
With the advent of smart homes, smart cities, and smart everything, the Internet of Things (IoT) has emerged as an area of incredible impact, potential, and growth, with Cisco Inc. predicting to have 50 billion connected devices by 2020. However, most of these IoT devices are easy to hack and compromise. Typically, these IoT devices are limited in compute, storage, and network capacity, and therefore they are more vulnerable to attacks than other endpoint devices such as smartphones, tablets, or computers. In this paper, we present and survey major security issues for IoT. We review and categorize popular security issues with regard to the IoT layered architecture, in addition to protocols used for networking, communication, and management. We outline security requirements for IoT along with the existing attacks, threats, and state-of-the-art solutions. Furthermore, we tabulate and map IoT security problems against existing solutions found in the literature. More importantly, we discuss, how blockchain, which is the underlying technology for bitcoin, can be a key enabler to solve many IoT security problems. The paper also identifies open research problems and challenges for IoT security.
Introduction
With the rapid growth of smart devices and high speed networks, the Internet of Things (IoT) has gained wide acceptance and popularity as the main standard for low-power lossy networks (LLNs) having constrained resources. It represents a network where ‘‘things’’ or embedded devices having sensors are interconnected through a private or a public network [1,2]. The devices in IoT can be controlled remotely to perform the desired functionality. The information sharing among the devices then takes place through the network which employs the standard protocols of communication. The smart connected devices or ‘‘things’’ range from simple wearable accessories to large machines, each containing sensor chips. For instance, the Lenovo smart shoes contain chips which provide support of tracking and analyzing fitness data [3]. Similarly, the electrical appliances including washing machines, and refrigerators can be controlled remotely through IoT. The security cameras installed for surveillance of a location can be monitored remotely anywhere in the world. Apart from the personal use, IoT serves the community needs as well. Various smart devices which perform diverse functionalities such as monitoring surgery in hospitals, detecting weather conditions, providing tracking and connectivity in automobiles, and identification of animals using biochips are already serving the community specific needs [4]. The data collected through these devices may be processed in real-time to improve efficiency of the entire system.
