Please see below for abstract. In recent years, the adoption of remote proctoring solutions for law schools and bar examshassurged. Yet, the integrity and fairness of these systems have come under scrutiny. Concurrently, post the September 11th attacks, the security of police radio systems, notably Motorola P25 and Harris OpenSky, has emerged as a significant concern. This thesis delves into the issues plaguing these real-world systems and forwards potential remedies. The initial segment of the thesis appraises the integrity and equitability of remote proctoring solutions. An extensive literature review on remote proctoring’s application in law schools and bar exams sets the stage, elucidating both the advantages and limitations of these platforms. The narrative then transitions to the inherent security challenges: threats to exam sanctity posed by students, and the overarching issues of unfairness and systemic discrimination at the institutional level. The subsequent section casts a spotlight on the security dimensions of police radio systems, with an emphasis on Motorola P25 and Harris OpenSky. A meticulous breakdown of these systems’ features, capabilities, and security vulnerabilities ensues. The discourse deepens by investigating real-world deployments of these platforms, capturing the authentic security tribulations encountered by police departments across the United States. Additionally, the repercussions of these security concerns on police efficacy and overall public safety are explored. Drawing from the insights garnered, this thesis recommends a suite of measures to enhance the security and fairness of remote proctoring platforms and fortify the security infrastructure of police radio systems. These encompass the incorporation of advanced encryption methodologies and other security protocols to shield sensitive information. Moreover, the formulation of ethnically diverse datasets and strategies to curtail bias and discrimination in remote proctoring systems are elaborated upon. In essence, this thesis offers a holistic examination of the security and fairness facets of remote proctoring tools and the robustness of police radio systems, culminating in actionable recommendations to ameliorate the identified challenges.
