Responsibility and non-repudiation in resource-constrained Internet of Things scenarios
The proliferation and popularity of smart
autonomous systems necessitates the development
of methods and models for ensuring the effective
identification of their owners and controllers. The aim
of this paper is to critically discuss the responsibility of
Things and their impact on human affairs. This starts
with an in-depth analysis of IoT Characteristics such
as Autonomy, Ubiquity and Pervasiveness. We argue
that Things governed by a controller should have an
identifiable relationship between the two parties and
that authentication and non-repudiation are essential
characteristics in all IoT scenarios which require
trustworthy communications. However, resources can
be a problem, for instance, many Things are designed
to perform in low-powered hardware. Hence, we also
propose a protocol to demonstrate how we can achieve the
authenticity of participating Things in a connectionless
and resource-constrained environment

Smart Home Automation System Using IOT
While the cost of living is going up, there is a growing focus to involve technology to lower those prices. With this in mind the Smart Home research allows the user to build and maintain a house that is smart enough to keep energy levels down while providing more automated applications. This concept can be suitably included to make our house smarter, saver, energy efficient and automated. This research focuses on building a save, automated system by using the internet connection that will smartly control the appliances like Lights, Fan, and other electrical appliances in our home. A smart home will take advantage of its environment and allow seamless control whether the user is present or away. This paper helps in saving the cost of electricity at home as well as saving the environment using wireless connections. With a home that has this advantage, you can know that your home is performing at its best in energy performance. By implementing this system, it is possible to explore a variety of different engineering challenges, including software programming arduino IDE, Wi-Fi, nodemcu, relay module, jumper wires and DC supply power. It can be control through smartphone. With prototype model, standard updates are basically a requirements. However, based on the result, this automation system provides great insights to the challenges of software and hardware design
Novel Attacks and Defenses for Enterprise Internet-of-Things (E-IoT) Systems
This doctoral dissertation expands upon the field of Enterprise Internet-of-Things (E-IoT) systems, one of the most ubiquitous and under-researched fields of smart systems. E-IoT systems are specialty smart systems designed for sophisticated automation applications (e.g., multimedia control, security, lighting control). E-IoT systems are often closed source, costly, require certified installers, and are more robust for their specific applications. This dissertation begins with an analysis of the current E-IoT threat landscape and introduces three novel attacks and defenses under-studied software and protocols heavily linked to E-IoT systems. For each layer, we review the literature for the threats, attacks, and countermeasures. Based on the systematic knowledge we obtain from the literature review, we propose three novel attacks and countermeasures to protect E-IoT systems. In the first attack, we present PoisonIvy, several attacks developed to show that malicious E-IoT drivers can be used to compromise E-IoT. In response to PoisonIvy threats, we describe Ivycide, a machine-learning network-based solution designed to defend E-IoT systems against E-IoT driver threats. As multimedia control is a significant application of E-IoT, we introduce is HDMI-Walk, a novel attack vector designed to demonstrate that HDMI\u27s Consumer Electronics Control (CEC) protocol can be used to compromise multiple devices through a single connection. To defend devices from this threat, we introduce HDMI-Watch, a standalone intrusion detection system (IDS) designed to defend HDMI-enabled devices from HDMI-Walk-style attacks. Finally, this dissertation evaluates the security of E-IoT proprietary protocols with LightingStrike, a series of attacks used to demonstrate that popular E-IoT proprietary communication protocols are insecure. To address LightningStrike threats, we introduce LGuard, a complete defense framework designed to defend E-IoT systems from LightingStrike-style attacks using computer vision, traffic obfuscation, and traffic analysis techniques. For each contribution, all of the defense mechanisms proposed are implemented without any modification to the underlying hardware or software. All attacks and defenses in this dissertation were performed with implementations on widely-used E-IoT devices and systems. We believe that the research presented in this dissertation has notable implications on the security of E-IoT systems by exposing novel threat vectors, raising awareness, and motivating future E-IoT system security research
A Review on Energy Consumption Optimization Techniques in IoT Based Smart Building Environments
In recent years, due to the unnecessary wastage of electrical energy in
residential buildings, the requirement of energy optimization and user comfort
has gained vital importance. In the literature, various techniques have been
proposed addressing the energy optimization problem. The goal of each technique
was to maintain a balance between user comfort and energy requirements such
that the user can achieve the desired comfort level with the minimum amount of
energy consumption. Researchers have addressed the issue with the help of
different optimization algorithms and variations in the parameters to reduce
energy consumption. To the best of our knowledge, this problem is not solved
yet due to its challenging nature. The gap in the literature is due to the
advancements in the technology and drawbacks of the optimization algorithms and
the introduction of different new optimization algorithms. Further, many newly
proposed optimization algorithms which have produced better accuracy on the
benchmark instances but have not been applied yet for the optimization of
energy consumption in smart homes. In this paper, we have carried out a
detailed literature review of the techniques used for the optimization of
energy consumption and scheduling in smart homes. The detailed discussion has
been carried out on different factors contributing towards thermal comfort,
visual comfort, and air quality comfort. We have also reviewed the fog and edge
computing techniques used in smart homes

The Computerized integrated smart home
The emergence of multiple home computers and the need to network them together are dramatically increasing in our society. At the same time, more and more methods of networking home computers are being developed. As our society becomes more reliant on using digital devices in our everyday lives, the possibility of a smart home can actually become a reality. My thesis will research currently available home automation products, and will propose a complete smart home system using current and possible future technologies. It will also include the various services that can be offered via home networking and automation. There are several component areas that must be considered and combined to create the complete system. Some of these areas include communications, device control, temperature, security, and most important, the user interface. One of the main components of the system will be the concept of a console , which will be the primary interface. My thesis will explore different kinds of consoles using existing and proposed technology, how they can be internetworked together to form a complete communications system, and how they can be connected to the outside world. The feasibility of offering home automation services using these consoles is another area that will be explored. For instance, can a home be considered secure if doors and locks are automated and integrated into the smart home? With the smart home, a user should be able to enter the house without a key, solely by communicating with the system. It could even be possible to lock a door from any console within the house, in case the user forgot. I believe the smart home is becoming a reality, and can propel our society into a new way of life as an advanced civilization. My thesis will attempt to provide various ways of making it a reality using current and possible future technologies. Although it will not provide a concrete example of a complete smart home system, that area of expansion exists for future research. Perhaps one day it will become a standard in new home development, and will change how we perform everyday tasks at home
