Promoting Distributed Accountability In The Cloud, Smitha Sundareswaran, Anna Squicciarini, Dan Lin, Shuo Huang

Computer Science Faculty Research & Creative Works

Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. a major feature of the cloud services is that users' data is usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users' fears of losing control of their own data (particularly financial and health data) can become a significant barrier to the wide adoption of cloud services. to address this problem, in this paper, we propose a novel highly decentralized information accountability framework to keep track of the actual …

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repository makes data and biospecimens from NIDDK-funded research available to the broader scientific community. It thereby facilitates: the testing of new hypotheses without new data or biospecimen collection; pooling data across several studies to increase statistical power; and informative genetic analyses using the Repository’s well-curated phenotypic data. This article describes the initial database plan for the Repository and its revision using a simpler model. Among the lessons learned were the trade-offs between the complexity of a database design and the costs in time and money of implementation; the …


Roar: A Reference Ontology For Anatomical Relations, Alton B. Coalter, Jennifer L. Leopold Sep 2011

Roar: A Reference Ontology For Anatomical Relations, Alton B. Coalter, Jennifer L. Leopold

Computer Science Faculty Research & Creative Works

The ontology has become a useful model for organizing knowledge. This is particularly true in the field of biomedicine, where individual ontologies have been created for specific data domains ranging from genomics through species morphologies to human anatomical reference ontologies. Although specific sets of relationships have been proposed to improve the accuracy and consistency of such ontologies, there has been little to nothing proposed concerning the organization of those relationships. to help address this deficiency, herein we present a Reference Ontology of Anatomical Relations (ROAR). ROAR extends the concepts used in existing biomedical ontologies by defining and hierarchically organizing temporal, …

Security Requirements Analysis, Specification, Prioritization And Policy Development In Cyber-Physical Systems, Kenneth Kofi Fletcher, Xiaoqing Liu

Computer Science Faculty Research & Creative Works

In recent past, the security of cyber-physical systems (CPSs) has been the subject of major concern. One of the reasons is that CPSs are often applied to mission-critical processes. Also, the automation CPSs bring in managing physical processes, and the detail of information available to them for carrying out their tasks, make securing them a prime importance. Securing CPSs is a difficult task as systems are interconnected. in order to achieve a continuous secured CPS environment, there is the need for an integrated methodology to analyze, specify and prioritize security requirements and also to develop policies to meet them. First, …

Drawbacks With It Outsourcing; Dealing With The End Of The Contract, Michael Muntean Sep 2011

Drawbacks With It Outsourcing; Dealing With The End Of The Contract, Michael Muntean

Regis University Student Publications (comprehensive collection)

Many companies have looked to outsourcing Information Technology infrastructure and business processes as a means to save capital and streamline company business and assets. While companies initially approach outsourcing engagements concentrating on the migration of data and services to the vendor company, they rarely take into account potential issues that could possibly cause an outsourcing engagement to fail. Failure to address these potential issues within the contract can lead a business to be stuck in an outsourcing engagement that offers little to no benefit to the company. This project presents the details of a survey performed at a business that …

Privacy-Preserving Transactions On The Web, Sahil Behl, Leszek T. Lilien

The Hilltop Review

There is a rapid growth in the number of applications using sensitive and personal information on the World Wide Web. This growth creates an urgent need to maintain the anonymity of the participants in many web transactions and to preserve the privacy of their sensitive data during data dissemination over the web. First, maintaining the anonymity of users on the World Wide Web is essential for a number of web applications. Anonymity cannot be assured by single interested individuals or an organization but requires participation from other web nodes owned by other entities. Second, preserving the privacy of sensitive data …

Investigation Of Efficient Unified Threat Management In Enterprise Security, Ryan Lynn

Regis University Student Publications (comprehensive collection)

This thesis explores the problems that exist today with perimeter security in data communications specifically the disparate architecture that exists to mitigate risk. Currently there are many different components to the enterprise security perimeter that are not cohesive and do not collaborate well to form an efficient, scalable, operationally supportable gateway design. The thesis breaks down this problem by illustrating the shortcomings of current technologies. These illustrations are used in conjunction with published research and authored research to provide solid footing for the idea of a unified threat management or UTM model. In this model, threat prevention techniques are consolidated …

Packed, Printable, And Polymorphic Return-Oriented Programming, Kangjie Lu, Dabi Zou, Weiping Wen, Debin Gao Sep 2011

Packed, Printable, And Polymorphic Return-Oriented Programming, Kangjie Lu, Dabi Zou, Weiping Wen, Debin Gao

Research Collection School Of Computing and Information Systems

Return-oriented programming (ROP) is an attack that has been shown to be able to circumvent W ⊕ X protection. However, it was not clear if ROP can be made as powerful as non-ROP malicious code in other aspects, e.g., be packed to make static analysis difficult, be printable to evade non-ASCII filtering, be polymorphic to evade signature-based detection, etc. Research in these potential advances in ROP is important in designing counter-measures. In this paper, we show that ROP code could be packed, printable, and polymorphic. We demonstrate this by proposing a packer that produces printable and polymorphic ROP code. It …


Numerical Ocean Modeling And Simulation With Cuda, Jason Mak, Paul Choboter, Chris Lupo Sep 2011

Numerical Ocean Modeling And Simulation With Cuda, Jason Mak, Paul Choboter, Chris Lupo

Computer Science and Software Engineering

ROMS is software that models and simulates an ocean region using a finite difference grid and time stepping. ROMS simulations can take from hours to days to complete due to the compute-intensive nature of the software. As a result, the size and resolution of simulations are constrained by the performance limitations of modern computing hardware. To address these issues, the existing ROMS code can be run in parallel with either OpenMP or MPI. In this work, we implement a new parallelization of ROMS on a graphics processing unit (GPU) using CUDA Fortran. We exploit the massive parallelism offered by modern …


Hide-N-Sense: Privacy-Aware Secure Mhealth Sensing, Shrirang Mare, Jacob Sorber, Minho Shin, Cory Cornelius, David Kotz Sep 2011

Hide-N-Sense: Privacy-Aware Secure Mhealth Sensing, Shrirang Mare, Jacob Sorber, Minho Shin, Cory Cornelius, David Kotz

Computer Science Technical Reports

As healthcare in many countries faces an aging population and rising costs, mobile sensing technologies promise a new opportunity. Using mobile health (mHealth) sensing, which uses medical sensors to collect data about the patients, and mobile phones to act as a gateway between sensors and electronic health record systems, caregivers can continuously monitor the patients and deliver better care. Furthermore, individuals can become better engaged in monitoring and managing their own health. Although some work on mHealth sensing has addressed security, achieving strong privacy for low-power sensors remains a challenge.

We make three contributions. First, we propose an mHealth sensing …


Bgrep And Bdiff: Unix Tools For High-Level Languages, Gabriel A. Weaver, Sean W. Smith Sep 2011

Bgrep And Bdiff: Unix Tools For High-Level Languages, Gabriel A. Weaver, Sean W. Smith

Computer Science Technical Reports

The rise in high-level languages for system administrators requires us to rethink traditional UNIX tools designed for these older data formats. We propose new block-oriented tools, bgrep and bdiff, operating on syntactic blocks of code rather than the line, the traditional information container of UNIX. Transcending the line number allows us to introduce longitudinal diff, a mode of bdiff that lets us track changes across arbitrary blocks of code. We present a detailed implementation roadmap and evaluation framework for the full version of this paper. In addition we demonstrate how the design of our tools already addresses several real-wold problems …

A Novel Malware Target Recognition Architecture For Enhanced Cyberspace Situation Awareness, Thomas E. Dube Sep 2011

A Novel Malware Target Recognition Architecture For Enhanced Cyberspace Situation Awareness, Thomas E. Dube

Theses and Dissertations

The rapid transition of critical business processes to computer networks potentially exposes organizations to digital theft or corruption by advanced competitors. One tool used for these tasks is malware, because it circumvents legitimate authentication mechanisms. Malware is an epidemic problem for organizations of all types. This research proposes and evaluates a novel Malware Target Recognition (MaTR) architecture for malware detection and identification of propagation methods and payloads to enhance situation awareness in tactical scenarios using non-instruction-based, static heuristic features. MaTR achieves a 99.92% detection accuracy on known malware with false positive and false negative rates of 8.73e-4 and 8.03e-4 respectively. …


Detecting Man-In-The-Middle Attacks Against Transport Layer Security Connections With Timing Analysis, Lauren M. Wagoner Sep 2011

Detecting Man-In-The-Middle Attacks Against Transport Layer Security Connections With Timing Analysis, Lauren M. Wagoner

Theses and Dissertations

The Transport Layer Security (TLS) protocol is a vital component to the protection of data as it traverses across networks. From e-commerce websites to Virtual Private Networks (VPNs), TLS protects massive amounts of private information, and protecting this data from Man-in-the-Middle (MitM) attacks is imperative to keeping the information secure. This thesis illustrates how an attacker can successfully perform a MitM attack against a TLS connection without alerting the user to his activities. By deceiving the client machine into using a false certificate, an attacker takes away the only active defense mechanism a user has against a MitM. The goal …


An Empirical Analysis Of The Cascade Secret Key Reconciliation Protocol For Quantum Key Distribution, Timothy I. Calver Sep 2011

An Empirical Analysis Of The Cascade Secret Key Reconciliation Protocol For Quantum Key Distribution, Timothy I. Calver

Theses and Dissertations

The need to share key material with authorized entities in a secure, efficient and timely manner has driven efforts to develop new key distribution methods. The most promising method is Quantum Key Distribution (QKD) and is considered to be “unconditionally secure” because it relies upon the immutable laws of quantum physics rather than computational complexity. Unfortunately, the nonidealities present in actual implementations of QKD systems also result in errors manifested in the quantum data channel. As a consequence, an important component of any QKD system is the error reconciliation protocol which is used to identify and correct inconsistencies in the …

Efficient Graph Algorithms Based On Color Coding Method, Kun Wang Sep 2011

Efficient Graph Algorithms Based On Color Coding Method, Kun Wang

Student Theses and Dissertations

Graph theory is the study of graphs in theoretical computer science. Graphs are mathematical models used to describe pairwise relations between objects from a certain collection. Many practical problems can be modeled as graphs problems, so it is of great importance to develop efficient graph algorithms for different graph problems based on high-throughput data. In this work, we study several important bioinformatics problems which are modeled as problems on weighted graphs, bounded local tree-width graphs, bounded-degree graphs, or mixed graphs etc. We design very efficient algorithms based on the color-coding method for these graph problems. We also apply the idea …
