Book Description
The rapid growth of Internet of things (IoT) including mobile phones, portable devices, and remote sensor network systems have imposed both conceptually and technically new challenges. Among them, the most demanding requirements for the widespread realization of many IoT visions are security and low power. In terms of security, IoT applications include tasks that are rarely addressed before such as trusted sensing, secure computation and communication, privacy, and data right management. These tasks ask for new and better techniques for the protection of hardware, software, and data. On the other hand, most of the IoT systems suffer from the problem of limited power sources, which in turn require the security on IoT devices to be lightweight. While low energy design is crucial for the successful deployment of resource-constrained IoT devices, their often physically accessible nature, as well as low energy budget restriction, have also contributed to rendering traditional cryptographic approaches insufficient to address all the security concerns. In this dissertation, we present hardware-oriented security designs and synthesis techniques with the aim to reduce the system energy overhead while maintaining the security and reliability. We first demonstrate our work to analyze and enhance the properties of hardware security primitives. We emphasize on physical unclonable functions (PUFs) and use them to enable a wide range of applications, including private/public key communication, authentication, and multi-party communication. We then present a unique system reliability design with the use of non-volatile memory (NVM) to create a fault-tolerance application specific architecture with almost no timing overhead and low energy overhead. Finally, we demonstrate novel energy reduction and synthesis techniques applied on integrated circuit subsystems of IoT applications. The techniques we have applied and improved include near-threshold computing, dual-supply voltage optimization, and pipelining.

Book Description
Internet of Things (IoT) is a revolutionary network that is envisioned to connect physical entities to the cyber world. IoT technology has fundamentally changed how we interact with our world. Worldwide spending on IoT is forecast to reach $745 Billion in 2019, and it is expected that investments in the technology will maintain double-digit growth rate for years to come. Despite wide adoption and strong anticipation in the technology, two major obstacles heavily constrained the further development in IoT, respectively security and energy challenges. From the security perspective, the entire lifecycle of an IoT device could potentially be vulnerable to various types of attacks. Since many devices are deployed in an insecure environment, attackers could gain unauthorized access to the exposed hardware, which invalidates many security assumptions made in traditional security research. From the energy perspective, many IoT devices are incapable of affording traditional cryptographical protection due to low energy and computation budget. Energy efficiency is therefore crucial for designs and establishments of IoT. To address IoT security problems, we explore and propose novel hardware-oriented security primitive designs and optimization techniques in this thesis. We first investigate the vulnerabilities of physically unclonable function (PUF), a popular low power hardware security primitive used in IoT devices, through the creation of a hardware emulation platform using programmable delay lines (PDL). To address vulnerabilities in PUFs, we propose a novel security primitive, Interconnected PUF Network (IPN), that interconnects small segments of strong PUFs in a reconfigurable network, limiting the single-bit prediction accuracy to as low as 53.19% against a wide range of modeling attacks. We demonstrated that the interconnections in an IPN can be optimized to maximize output randomness and stability using our proposed evolution-strategies-based algorithm. Looking beyond PUF-based security, we designed content-driven injective functions (CRIF) that rearrange compositions of hardware injective functions based on previous messages, providing secure message encryption/decryption between IoT devices. Facing the energy challenges, we propose ``computing while racing" technique that reduces 40.4% of area overhead and 7.69% of power when implementing arbiter PUF and arbitrary logic on field-programmable-gate-arrays (FPGAs). This is achieved through encoding digital signals in analog forms and achieves a high percentage of hardware sharing, suggesting resource sharing could potentially be a promising direction for power/energy reduction in IoT devices. Eventually, we propose two practical IoT applications. We first design a device anomaly detection utilizing the inconsistency in environmentally sensitive PUF challenge-response pairs. We show that our detector is more flexible and more power-efficient compared to state-of-the-art system monitors. Secondly, we demonstrate that our proposal of PUF-assisted group key management protocol securely protects IoT group communications while reducing global energy consumption by 47.3% compared to cryptographic key management solutions.

Book Description
The Internet of Things (IoT) integrates heterogeneous devices, ranging from sensors to smartphones, tablets and edge servers, and can provide a variety of services, beyond the traditional Internet. Unfortunately, due to its unprecedented scale and ubiquity, IoT faces a maintainability challenge and a set of interrelated problems. With the emergence of edge computing, IoT devices execute various tasks that consume a significant amount of power to deliver high quality of service, which can drain their battery in short time. High peak power increases the device temperature stress, which worsens the impact of transistors and interconnects reliability degradation mechanisms. Such mechanisms lead to early device failures and are costly to fix. In this dissertation, we focus on novel solutions for energy-efficient and reliability-driven management of IoT systems. We introduce a simulation framework called RelIoT to enable reliability evaluation and analysis in IoT networks, which paves the way for the development of new network management solutions. We develop a dynamic reliability management technique based on computation offloading for IoT edge computing architectures. Our approach achieves 20.5% longer mean time to failure than the next best network management solution. We also present an adaptive and distributed reliability-aware routing protocol using reinforcement learning. We show that our routing protocol can improve reliability of a network up to 73.2% compared to state-of-the-art routing approaches. The main focus inall our solutions is to use device batteries efficiently, satisfy QoS requirements, and improve overall network lifetime by mitigating reliability degradation. Lastly, we complement this to specifically study battery health and associated degradation mechanisms, as the traditional techniques developed for optimizing the energy consumption of networks do not yield optimal battery life. An improvement in network lifetime up to 68.5% can be achieved with our approach compared to energy consumption optimization approaches.

Book Description
Our research explores the intersection of academic, industrial and standardization spheres to enable secure and energy-efficient Internet of Things. We study standards-based security solutions bottom-up and first observe that hardware accelerated cryptography is a necessity for Internet of Things devices, as it leads to reductions in computational time, as much as two orders of magnitude. Overhead of the cryptographic primitives is, however, only one of the factors that influences the overall performance in the networking context. To understand the energy - security tradeoffs, we evaluate the effect of link-layer security features on the performance of Wireless Sensors Networks. We show that for practical applications and implementations, link-layer security features introduce a negligible degradation on the order of a couple of percent, that is often acceptable even for the most energy-constrained systems, such as those based on harvesting.Because link-layer security puts trust on each node on the communication path consisted of multiple, potentially compromised devices, we protect the information flows by end-to-end security mechanisms. We therefore consider Datagram Transport Layer Security (DTLS) protocol, the IETF standard for end-to-end security in the Internet of Things and contribute to the debate in both the standardization and research communities on the applicability of DTLS to constrained environments. We provide a thorough performance evaluation of DTLS in different duty-cycled networks through real-world experimentation, emulation and analysis. Our results demonstrate surprisingly poor performance of DTLS in networks where energy efficiency is paramount. Because a DTLS client and a server exchange many signaling packets, the DTLS handshake takes between a handful of seconds and several tens of seconds, with similar results for different duty cycling protocols.But apart from its performance issues, DTLS was designed for point-to-point communication dominant in the traditional Internet. The novel Constrained Ap- plication Protocol (CoAP) was tailored for constrained devices by facilitating asynchronous application traffic, group communication and absolute need for caching. The security architecture based on DTLS is, however, not able to keep up and advanced features of CoAP simply become futile when used in conjunction with DTLS. We propose an architecture that leverages the security concepts both from content-centric and traditional connection-oriented approaches. We rely on secure channels established by means of DTLS for key exchange, but we get rid of the notion of “state” among communicating entities by leveraging the concept of object security. We provide a mechanism to protect from replay attacks by coupling the capability-based access control with network communication and CoAP header. OSCAR, our object-based security architecture, intrinsically supports caching and multicast, and does not affect the radio duty-cycling operation of constrained devices. Ideas from OSCAR have already found their way towards the Internet standards and are heavily discussed as potential solutions for standardization.
