Unified RAW Path Oblivious RAM
Oblivious RAM (ORAM) is a cryptographic primitive that conceals memory access patterns to untrusted storage. Its applications include oblivious cloud storage, trusted processors, software protection, secure multi-party computation, and so on. This thesis improves the state-of-the-art Path ORAM in …

Oblivious RAM : from theory to practice
… a cryptographic primitive called Oblivious RAM (ORAM) which provably hides a client's access pattern as seen by untrusted storage. While ORAM is very compelling from a privacy standpoint, it incurs a large performance overhead. In particular, ORAM schemes require the client to continuously …

Optimal Oblivious RAM with Integrity
Oblivious RAM (ORAM), introduced by Goldreich and Ostrovsky (J. ACM ’96), is a protocol that allows a client to perform RAM computations on a server without revealing any information about the underlying data, even via the access pattern. For a memory of size N, well-known lower bounds show that a …

Searching over encrypted data
… searchable encryption (SSE) and oblivious RAM (ORAM) as the two potential and main cryptographic primitives candidate for real life settings. We have recognized several challenges and issues inherent to these constructions and provided a number of contributions that improve upon the state of the …

Secure Computation in Decentralized Systems
… An Improved Distributed Point Function (DPF) and ORAM: A major theoretical contribution of this work is a novel three-party Distributed Point Function (DPF) construction. This leads to state-of-the-art Oblivious RAM (ORAM) and Distributed ORAM (DORAM) protocols, which are important building blocks …

Amphibian Community Similarity Between Natural Ponds And Constructed Ponds Of Multiple Types In Daniel Boone National Forest, Kentucky
… depth, Ohio Wetland Rapid Assessment Score (ORAM), and pond type were recorded to examine relationships between amphibian species and habitat variables. Community comparisons were made using canonical correspondence analysis (CCA) and one-way analysis of similarity (ANOSIM). Stepwise …

DOMESTIC VIOLENCE IN A CHILD WELFARE CONTEXT: INTERPERSONAL VIOLENCE, POVERTY, AND THEIR LINK TO PARENTING ABILITIES
… scores on the Ontario Risk Assessment Model (ORAM). The findings indicated that poverty compromised the parenting abilities of mothers in this sample. This study challenged current literature on domestic violence and parenting, which emphasizes deficiencies in the parenting of women who are …

Oblivious RAM in Scalable SGX
… data. This thesis proposes and implements an ORAM controller primitive in TEE and protects it from all potential side-channel attacks. This thesis presents two vari- ations, each with two different encryption methods designed to mitigate attacks targeting both memory access patterns and …

The Role of the Ca2+-dependent protein kinase, CaMK-II, in Heart and Kidney Development in the Zebrafish, Danio rerio
… of tbx5, the gene mutated in patients with Holt-Oram Syndrome. Camk2g1 morphants also exhibit similar defects as suppression of pkd2, the gene mutated in patients with Autosomal Dominant Polycystic Kidney disease. These roles implicate CaMK-II as an integral protein in the development and …

Sanctum : minimal architectural extensions for isolated execution
… of magnitude less than what is incurred by ORAM-enabled processors. Our modifications cause a 2% area increase to the Rocket core. Over a set of benchmarks, Sanctum's worst observed overhead for isolated execution is 15.1% over an idealized insecure baseline, and 2.7% average overhead over a …

Computer support of collaborative case based learning by MBA students
Many UK MBA programmes adopt a collaborative approach to the Harvard style of experiential case based learning. Within such programmes there is widespread use of computers but it is not clear how this improves student learning. Research on computer support of collaborative learning in other …

Biorefining Sewage for Energy and Green Chemicals
Anaerobic digestion (AD) has become a well-established method for the treatment of organic wastes, such as sewage sludge, whilst recovering valuable products in the process. Typically, AD produces biogas in the form of carbon dioxide and methane but environmental concerns surrounding fugitive …

"What alternative punishment is there?": Military Executions During World War I
The power to inflict the death penalty formed a vital part of the disciplinary process in all the major armies during the First World War. Yet serious historians have neglected the subject. This thesis addresses the topic in a critical manner and challenges the view that executions were arbitrary, …

Revision of the Genus Hylaeus Fabricius (Hymenoptera: Colletidae) in Canada
Hylaeus Fabricius (Hymenoptera, Colletidae) is a genus of bees that can be readily recognized by the relatively hairless black bodies with yellow maculations (markings) on the face and thorax, including the legs. However, species-level identification is difficult due to the maculations of many …

Consultation as a vehicle for increasing novice teachers' use of evidence-based classroom management strategies
Teachers' classroom management skills have a significant impact on students' short and long-term outcomes. Unfortunately, research has demonstrated that teachers, particularly novice teachers, often struggle to effectively manage classrooms and student behavior. Teacher consultation, which is …

The potentiometric determination of the formation constants of a novel class of macrocyclic polyaminocarboxylic acid ligands and the formation constants of the mercury(II)-glutathione complexes
Potentiometric titrations were used to determine the thermodynamic formation constants of the complexes of newly synthesized macrocyclic polyaminocarboxylic acid ligands with selected metal ions. The formation constants were calculated with the help of a computer modeling program, BEST. Protonated …
