Security-policy analysis with eXtended unix tools / by Gabriel A. Weaver.
During our fieldwork with real-world organizations---including those in Public Key Infrastructure (PKI), network configuration management, and the electrical power grid---we repeatedly noticed that security policies and related security artifacts...

Spectroscopic analyses of type Ia supernovae / by Jerod Parrent.
After decades of searching we have yet to find the progenitor systems for type Ia supernovae. In fact most of what we know about this homogeneous class of supernovae is from spectral features associated with the incinerated remains of the C+O white...

SHEMP: secure hardware enhanced MyProxy.
Public key infrastructure (Computer security). ; Computer networks -- Security measures. ; Operating systems (Computers). ; Microcomputers.
In 1976, Whitfield Diffie and Martin Hellman demonstrated how public key cryptography could enable secure information exchange between parties that do not share secrets. In order for public key cryptography to work in modern distributed...

Attribute-based, usefully secure email.
Electronic mail systems -- Security measures. Electronic mail systems -- Social aspects. Trust.
A secure system that cannot be used by real users to secure real-world processes is not really secure at all. While many believe that usability and security are diametrically opposed, a growing body of research from the field of Human-Computer...

Hardware-Assisted Secure Computation.
Computer networks -- Security measures. Computer networks -- Access control. Computer network protocols.
The theory community has worked on Secure Multiparty Computation (SMC) for more than two decades, and has produced many protocols for many settings. One common thread in these works is that the protocols cannot use a Trusted Third Party (TTP), even...

The Matrix Metalloproteinase-1/protease activated receptor-1 signaling axis in melanoma progression.
Collagenases -- Pathophysiology. Metalloproteinases -- Pathophysiology. Melanoma -- Molecular aspects. Matrix Metalloproteinase 1.
The inappropriate expression of Matrix Metalloproteinases (MMPs) contributes to the pathology of many cancers. Among these, melanoma is a particularly insidious disease in that it is almost completely resistant to every known the therapy, and the...

Usable security for wireless body-area networks / by Cory Cornelius.
We expect wireless body-area networks of pervasive wearable devices will enable in situ health monitoring, personal assistance, entertainment personalization, and home automation. As these devices become ubiquitous, we also expect them to...

Bayesian statistical models for adaptive image restoration and enhancement / by James M. Hughes.
Multiresolution image transformations have become commonplace tools for analyzing images for a number of applications, including enhancement and restoration. Powerful models for these applications have been developed in the transform domain of...

Photo forensics from partial constraints / by Eric Lee.
A variety of forensic methods have been developed to identify falsified photos, each unified by the ability to estimate and detect properties of a photo that are perturbed by forgery. There exist, however, many photos in which the required...

Automated forensic techniques for locating zero-day exploits / by Stephen Kuhn.
This thesis approaches the problem of locating zero-day exploits used in network attacks. The hypothesis is that the advent of high-performance virtualization presents a unique opportunity to both discover these events and increase the attacker's...

Digital video forensics.
Digital video -- Analysis. Forensic sciences. Image processing -- Digital techniques.
We present new forensic tools that are capable of detecting traces of tampering in digital video without the use of watermarks or specialized hardware. These tools operate under the assumption that video contain naturally occurring properties which...

Natural image statistics for digital image forensics.
Image processing -- Statistical methods. Image processing -- Digital techniques. Images
We describe a set of natural image statistics that are built upon two multi-scale image decompositions, the quadrature mirror filter pyramid decomposition and the local angular harmonic decomposition. These image statistics consist of first- and...
