As the digital world evolves, so does the risk of cyberattacks. Despite technology playing a vital role in nullifying these threats, the human factor is still regarded as one of the greatest weaknesses. End-user behavior is a major cause of information security breaches. This quantitative empirical study used a single-group, pre-post-test,…

The requirement that schools must monitor student internet use is not a new concept to K-12 education; however, the use of safety management platforms (SMPs) to help with this task is new. These tools utilize artificial intelligence to sift through the data attached to student information and communications technology (ICT) use and report it back…

The purpose of this quantitative study was to explore the influence of protection motivation theory (PMT) constructs on security behaviors of undergraduate students. More specifically, the primary focus of this study is to answer our primary research question: to what extent do the independent variables (perceived threat severity, perceived threat…

Mobile devices are rapidly becoming a very popular and convenient means of delivering and consuming learning content worldwide. The rise in popularity is due in part to the technological advancements that mobile devices have made in recent years, along with developments in the online learning platforms and spaces that support mobile learning.…

This thesis identifies three essays which contribute to the foundational understanding of the vulnerabilities and risk towards potentially implementing wireless grid Edgeware technology in a virtualized cloud environment. Since communication networks and devices are subject to becoming the target of exploitation by hackers (e.g. individuals who…

Trust management in mobile networks is challenging due to dynamically changing network environments and the lack of a centralized trusted authority. In this dissertation research, we "design" and "validate" a class of dynamic trust management protocols for mobile networks, and demonstrate the utility of dynamic trust management…

Telecommunications carriers and service providers now play an essential role in facilitating modern surveillance by law enforcement agencies. The police merely select the individuals to be monitored, while the actual surveillance is performed by third parties: often the same email providers, search engines and telephone companies to whom consumers…

The major challenges facing resource constraint wireless devices are error resilience, security and speed. Three joint schemes are presented in this research which could be broadly divided into error correction based and cipher based. The error correction based ciphers take advantage of the properties of LDPC codes and Nordstrom Robinson code. A…

In this dissertation, we present novel physical (PHY) and cross-layer design guidelines and resource adaptation algorithms to improve the security and user experience in the future wireless networks. Physical and cross-layer wireless security measures can provide stronger overall security with high efficiency and can also provide better…

This dissertation consists of three essays that examine, in three specific contexts, issues related to pricing of information goods and services. As the ability to measure technology resource usage gets easier with increased connectivity, the question whether a technology resource should be priced by the amount of the resource used or by the…

Wireless ad hoc networks are suitable and sometimes the only solution for several applications. Many applications, particularly those in military and critical civilian domains (such as battlefield surveillance and emergency rescue) require that ad hoc networks be secure and stable. In fact, security is one of the main barriers to the extensive use…

With increasing demand of mobile devices and cloud computing, it becomes increasingly important to develop efficient mobile application and its secured backend, such as web applications and virtualization environment. This dissertation reports a systematic study of mobile application development and the security issues of its related backend. …

Wireless Sensor Networks (WSNs) have unique characteristics which constrain them; including small energy stores, limited computation, and short range communication capability. Most traditional security algorithms use cryptographic primitives such as Public-key cryptography and are not optimized for energy usage. Employing these algorithms for the…

The nation's critical infrastructure, information systems, and telecommunication networks are vulnerable and threatened by an ever-growing number of attacks in cyberspace. An essential element of the nation's comprehensive approach to cybersecurity is the ability for the Department of Defense to protect and defend its information enterprise.…

This dissertation deals with a multiterminal source model for secret key generation by multiple network terminals with prior and privileged access to a set of correlated signals complemented by public discussion among themselves. Emphasis is placed on a characterization of secret key capacity, i.e., the largest rate of an achievable secret key,…
