PhD Student Yaman Sharaf-Dabbagh successfully defends his dissertation entitled "Security and Privacy of Internet of Things: Authentication and Blockchain".
Reaping the benefits of the Internet of things (IoT) system is contingent upon developing IoT-specific security and privacy solutions. Conventional security and authentication solutions often fail to meet IoT requirements due to the computationally limited and portable nature of IoT objects. Privacy in IoT is major issue as well in the light of current attacks on Facebook, and Uber. Blockchain on the other hand is an emerging technology with the potential to end the corporations control over our personal information.
This dissertation, investigates the use of blockchain in IoT systems. The proposed frameworks and solutions are designed to address the main issues faced by blockchain and IoT systems. This dissertation led to the following key contributions. First, a novel lightweight framework, called DShard, that supports low energy devices. The framework utilizes blockchain to solve the limitations of scalability, centralization, and privacy. The framework is able to support small devices with low energy capabilities by dynamically grouping the devices in the system into smaller blockchain based systems called shards. Each shard has a subset of the devices in the system and a portion of the Blockchain. To secure each shard against 51% attacks, the framework determines the type of each device in the system and uses these information to insure all shards are balanced. Second, an IoT objects authentication framework is proposed. The framework uses device-specific information, called fingerprints, along with a transfer learning tool to authenticate objects in the IoT. The framework tracks the effect of changes in the physical environment on fingerprints and uses unique IoT environmental effects features to detect both cyber and cyber-physical emulation attacks. The proposed environmental effects estimation framework is proven to improve the detection rate of attackers without increasing the false positives rate. The proposed framework is also shown to be able to detect cyber-physical attackers that are capable of replicating the fingerprints of target objects which conventional methods are unable to detect. A transfer learning approach is proposed to allow the use of objects with different types and features in the environmental effects estimation process to enhance the performance of the framework while capturing practical IoT deployments with diverse object types.

PhD Student Abdelrahman Eldosouky successfully defends his dissertation entitled "Security of Critical Cyber-Physical Systems: Fundamentals and Optimization".
Cyber-physical systems (CPSs) are systems that integrate physical elements with a cyber layer that enables sensing, monitoring, and processing the data from the physical components. Examples of CPSs include autonomous vehicles, unmanned aerial vehicles (UAVs), smart grids, and the Internet of Things (IoT). In particular, many critical infrastructure (CI) that are vital to our modern day cities and communities, are CPSs. This wide range of CPSs domains represents a cornerstone of smart cities in which various CPSs are connected to provide efficient services. However, this level of connectivity has brought forward new security challenges and has left CPSs vulnerable to many cyber-physical attacks and disruptive events that can utilize the cyber layer to cause damage to both cyber and physical components. Addressing these security and operation challenges requires developing new security solutions to prevent and mitigate the effects of cyber and physical attacks as well as improving the CPSs response in face of disruptive events, which is known as the CPS resilience.
To this end, the primary goal of this dissertation is to develop novel analytical tools that can be used to study, analyze, and optimize the resilience and security of critical CPSs. In particular, this dissertation presents a number of key contributions that pertain to the security and the resilience of multiple CPSs that include power systems, the Internet of Things (IoT), UAVs, and transportation networks. First, a mathematical framework is proposed to analyze and mitigate the effects of GPS spoofing attacks against UAVs. The proposed framework uses system dynamics to model the optimal routes which UAVs can follow in normal operations and under GPS spoofing attacks. A countermeasure mechanism, built on the premise of cooperative localization, is then developed to mitigate the effects of these GPS spoofing attacks. To practically deploy the proposed defense mechanism, a dynamic Stackelberg game is formulated to model the interactions between a GPS spoofer and a drone operator. The equilibrium strategies of the game are analytically characterized and studied through a novel, computationally efficient algorithm. Simulation results show that, when combined with the Stackelberg strategies, the proposed defense mechanism will outperform baseline strategy selection techniques in terms of reducing the possibility of UAV capture. Next, a game-theoretic framework is developed to model a novel moving target defense (MTD) mechanism that enables CPSs to randomize their configurations to proactive deter impending attacks. By adopting an MTD approach, a CPS can enhance its security against potential attacks by increasing the uncertainty on the attacker. The equilibrium of the developed single-controller, stochastic MTD game is then analyzed. Simulation results show that the proposed framework can significantly improve the overall utility of the defender. Third, the concept of MTD is coupled with new cryptographic algorithms for enhancing the security of an mHealth Internet of Things (IoT) system. In particular, using a combination of theory and implementation, a framework is introduced to enable the IoT devices to update their cryptographic keys locally to eliminate the risk of being revealed while they are shared.
Considering the resilience of CPSs, a novel framework for analyzing the component- and systemlevel resilience of CIs is proposed. This framework brings together new ideas from Bayesian networks and contract theory – a Nobel prize winning theory – to define a concrete system-level resilience index for CIs and to optimize the allocation of resources, such as redundant components, monitoring devices, or UAVs to help those CIs improve their resilience. In particular, the developed resilience index is able to account for the effect of CI components on the its probability of failure. Meanwhile, using contract theory, a comprehensive resource allocation framework is proposed enabling the system operator to optimally allocate resources to each individual CI based on its economic contribution to the entire system. Simulation results show that the system operator can economically benefit from allocating the resources while dams can have a significant improvement in their resilience indices. Subsequently, the developed contract-theoretic framework is extended to account for cases of asymmetric information in which the system operator has only partial information about the CIs being in some vulnerability and criticality levels. Under such asymmetry, it is shown that the proposed approach maximizes the system operator’s utility while ensuring that no CI has an incentive to ask for another contract. Next, a proof-of-concept framework is introduced to analyze and improve the resilience of transportation networks against flooding. The effect of flooding on road capacities and on the free-flow travel time, is considered for different rain intensities and roads preparedness. Meanwhile, the total system’s travel time before and after flooding is evaluated using the concept of a Wardrop equilibrium. To this end, a proactive mechanism is developed to reduce the system’s travel time, after flooding, by shifting capacities (available lanes) between same road sides. In a nutshell, this dissertation provides a suite of analytical techniques that allow the optimization of security and resilience across multiple CPSs.

The coming decade will be marked by a large-scale, pervasive wireless interconnection of devices, sensors, smartphones, tablets, wearable devices, vehicles, drones, and mundane objects into a massive cyber-physical Internet of Everything (IoE) system. It is anticipated that the IoE will provide connectivity for billions of devices and millions of individuals worldwide. However, such an interconnection will only be possible if a reliable and high-speed wireless communication infrastructure is built to sustain the massive and heterogeneous traffic that will stem from the IoE. Such an infrastructure will encompass a variety of wireless systems, ranging from cellular networks to WLANs. Owing to its pervasiveness, scale, and heterogeneity, the IoE will introduce many novel and unique challenges for wireless communications that range from enabling a co-existence between machine type devices and human type devices to delivering ultra-low latency communication and developing resource allocation mechanisms that can adapt to the heterogeneous IoE environment. Moreover, the IoE will also incorporate emerging technologies such as drone-based and UAV communications which will have their own, unique challenges.

Cyber-physical systems are characterized by four key features: Heterogeneity, in terms of technology and services.
Dynamics, in terms of rapidly varying environments and uncertainty at both the cyber and physical realms.
Size, in terms of number of users, nodes, and services.
Cyber-physical vulnerabilities, that can stem from multiple cyber and physical entry points.
The need for smart, secure, and autonomic CPS system designs has become a central research issue in a variety of applications and scenarios. One example is next-generation smart grid systems in which a myriad of devices such as renewable energy sources, customer-owned storage units, and traditional generator units must be able to interact, co-exist, and self-adapt to uncertainties and time-varying environments. Another example is the Internet of things system, which will encompass a broad range of devices, of different capabilities, that must interact, operate, and control various cyber and physical operations. Incorporating self-organizing optimization capabilities along with smarter security solutions in heterogeneous CPSs motivates the development of innovative analytical techniques.
