Git As An Encrypted Distributed Version Control System, Russell G. Shirey 2015 Air Force Institute of Technology

Git As An Encrypted Distributed Version Control System, Russell G. Shirey

Theses and Dissertations

This thesis develops and presents a secure Git implementation, Git Virtual Vault (GV2), for users of Git to work on sensitive projects with repositories located in unsecure distributed environments, such as in cloud computing. This scenario is common within the Department of Defense, as much work is of a sensitive nature. In order to provide security to Git, additional functionality is added for confidentiality and integrity protection. This thesis examines existing Git encryption implementations and baselines their performance compared to unencrypted Git. Real-world Git repositories are examined to characterize typical Git usage and determine if the existing Git encryption implementations …

In 2013 and 2014, we have continually heard about data security breaches and cybersecurity has become a major concern for the legal community. Reports of information leakage and security breach concerns at legal information vendors, firms, universities, and even courts continued to increase. Ms. Jackson addresses the increasing cybersecurity concerns and suggests some considerations for law librarian, legal information professionals, and the organizations they serve in determining the measures to address security threats.

Cloud Computing Risks And Risk Management, Anthony Hopkins 2014 Bridgewater College

Cloud Computing Risks And Risk Management, Anthony Hopkins

Senior Seminars

Cloud computing is an emerging technology that is becoming more and more popular every year. With the many benefits that the cloud provides it is hard for corporations not to integrate it into their business operations. With the increase usage in cloud computing substantial risks and concerns are beginning to surface. External data breaches, malicious insiders, outages, vendor lock-in, and insufficient due diligence are a couple of the major risks and concerns that need to be on the minds of the customer and the cloud service provider. The customer and the provider needs to know how to mitigate the risks …


Directed Graph Cryptosystems, Kurt Anson Boberg 2014 Central Washington University

Directed Graph Cryptosystems, Kurt Anson Boberg

All Master's Theses

Cryptography is a necessary tool for secrecy in our increasingly connected and data-driven world. As advances are made in both mathematics and com­puter hardware design, existing cryptosystems must be improved or replaced to maintain privacy of sensitive data. In this paper we propose a novel cryptosystem based upon an algorithmic traversal of a directed graph (digraph). The sys­tem is resistant to the most common attacks on stream-type ciphers that do not use known-plaintext attacks. However, given a length n, the minimum number of vertices a digraph must contain to guarantee a cycle of at least n length is un­known, making …

Exploitation Of Rf-Dna For Device Classification And Verification Using Grlvqi Processing, Donald R. Reising 2012 Air Force Institute of Technology

Exploitation Of Rf-Dna For Device Classification And Verification Using Grlvqi Processing, Donald R. Reising

Theses and Dissertations

This dissertation introduces a GRLVQI classifier into an RF-DNA fingerprinting process and demonstrates applicability for device classification and ID verification. Unlike MDA/ML processing, GRLVQI provides a measure of feature relevance that enables Dimensional Reduction Analysis (DRA) to enhance the experimental-to-operational transition potential of RF-DNA fingerprinting. Using 2D Gabor Transform RF-DNA fingerprints extracted from experimentally collected OFDM-based 802.16 WiMAX and 802.11 WiFi device emissions, average GRLVQI classification accuracy of %C greater than or equal to 90% is achieved using full and reduced dimensional feature sets at SNR greater than or equal to 10.0 dB and SNR greater than or equal to …

Design And Analysis Of A Dynamically Configured Log-Based Distributed Security Event Detection Methodology, Michael R. Grimaila, Justin M. Myers, Robert F. Mills, Gilbert L. Peterson

Military and defense organizations rely upon the security of data stored in, and communicated through, their cyber infrastructure to fulfill their mission objectives. It is essential to identify threats to the cyber infrastructure in a timely manner, so that mission risks can be recognized and mitigated. Centralized event logging and correlation is a proven method for identifying threats to cyber resources. However, centralized event logging is inflexible and does not scale well, because it consumes excessive network bandwidth and imposes significant storage and processing requirements on the central event log server. In this paper, we present a flexible, distributed event …

Cloud Storage, Matthew G. Chaulklin 2012 Bridgewater College

Cloud Storage, Matthew G. Chaulklin

Senior Seminars

Technology is forever changing in our world today. The way in which we receive information must match the convenience of our current technology. As of now most information that is stored is often restricted to the site of the server when one wants to access it. Cloud storage can change this process by allowing users anywhere to access the information they need. This technology is a solution to our storage problems as it is convenient for any user to obtain information. Unfortunately this technology has various large problems, like security, but hopefully in the future these can be solved. Overall, …


An Empirical Analysis Of The Cascade Error Reconciliation Protocol For Quantum Key Distribution, Timothy I. Calver, Michael R. Grimaila, Jeffrey W. Humphries 2011 Center for Cyberspace Research, Air Force Institute of Technology

An Empirical Analysis Of The Cascade Error Reconciliation Protocol For Quantum Key Distribution, Timothy I. Calver, Michael R. Grimaila, Jeffrey W. Humphries

Faculty Publications

Modern cryptography provides the means to securely communicate data between authorized entities by using mathematical transformations which require pre-shared cryptographic keys. The need to share key material with authorized entities in a secure, cost efficient and timely manner has driven efforts to develop new key distribution methods. A promising method is Quantum Key Distribution (QKD) which is considered to be “unconditionally secure” because it relies upon the immutable laws of quantum physics rather than computational complexity as the basis for its security. An important component of any QKD system is the error reconciliation protocol which is used to identify and …


A Novel Malware Target Recognition Architecture For Enhanced Cyberspace Situation Awareness, Thomas E. Dube 2011 Air Force Institute of Technology

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 Software Attacks By Monitoring Electric Power Consumption Patterns, Grant A. Jacoby, Nathaniel J. Davis IV, Randolph C. Marchany 2011 Air Force Institute of Technology

Detecting Software Attacks By Monitoring Electric Power Consumption Patterns, Grant A. Jacoby, Nathaniel J. Davis Iv, Randolph C. Marchany

AFIT Patents

Software attacks such as worms and viruses are detected in an electronic device by monitoring power consumption patterns. In a first embodiment, software attacks are detected by an increase in power consumption. The increased power consumption can be caused by increased network traffic, or by increased activity in the microprocessor. Monitoring power consumption is particularly effective for detecting DOS/flooding attacks when the electronic device is in an idle state. In a second embodiment, a power consumption signal is converted to the frequency domain (e.g., by fast Fourier transform). The highest amplitude frequencies are identified. Specific software attacks produce characteristic frequencies …
