Exploits in Concurrency for Boolean Satisfiability
Boolean Satisfiability (SAT) is a problem that holds great theoretical significance along with effective formulations that benefit many real-world applications. While the general problem is NP-complete, advanced solver algorithms and heuristics allow for fast solutions to many large industrial …

Design of a medium access control protocol that exploits the structures of vehicular networks
Vehicular networks (VANETs) have distinctive structures that distinguish them in comparison to general mobile ad hoc networks. In this thesis we identify the relevant special structures that do exist, and show how they can be exploited to design a MAC layer that provides better performance than a …

A model to study cyber attack mechanics and denial-of-service exploits over the internet's router infrastructure using colored petri nets
<p>The Internet‟s router infrastructure, a scale-free computer network, is vulnerable to targeted denial-of-service (DoS) attacks. Protecting this infrastructure‟s stability is a vital national interest because of the dependence of economic and national security transactions on the Internet. …

Automated exploitation of fully randomized executables
… and buffer overflow vulnerabilities to generate exploits that are robust against defenses, compilation decisions, and environment differences. Marten has generated four control flow hijacking exploits and three information leakage exploits. One of the information leakage exploits is generated …

ALFA-Chains: An Artificial Intelligence Approach to Exploit Chain Discovery in Networks
… valuable targets by executing the right exploits in the right order. However, finding these exploits chains is a challenging task requiring a broad knowledge of the vulnerabilities present in computer systems and the exploits that take advantage of them. Networks can be complex, with many …

A Framework for Deriving Verification and Validation Strategies to Assess Software Security
In recent years, the number of exploits targeting software applications has increased dramatically. These exploits have caused substantial economic damages. Ensuring that software applications are not vulnerable to the exploits has, therefore, become a critical requirement. The last line of defense …

Using Genetic Algorithms to Detect Security Related Software Parameter Chains
… can be attributed to misconfigured software. Exploits can be caused by a single parameter setting or a combination of settings. Identifying these parameter settings that are responsible for the exploits is difficult, as configurations often consist of hundreds of thousands of parameters. Some …

A Defense-In-Depth Security Architecture for Software Defined Radio Systems
… this threat. We also demonstrate example exploits of waveforms which can result in either a denial-of-service or a compromise of the system from a wireless attack vector. These example exploits target vulnerabilities such as overflows, unsanitized control inputs, and unexpected state …

Automatic Exploit Generation for Cross-Language Attacks
… is an essential component of most computer exploits. At the same time, a significant portion of legacy system software is written in C/C++, which are known to be memory-unsafe. This has led to an arms race between attackers devising ever clever ways to execute memory corruption and …

SYSTEMATIC METHODS FOR MEMORY ERROR DETECTION AND EXPLOITATION
… threats to computer systems. Memory error exploits have resulted in severe damage in real-world programs. At the same time, exploit mechanisms are rapidly evolving to bypass known protections. To prevent the damage, we need to detect them in advance and predict their evolving trend. In this …

Stochastic Space-Charge in Projection Electron Lithography and High Resolution Transmission Electron Microscopy
… distinct mechanisms of image formation--SCALPEL exploits amplitude contrast while HRTEM exploits phase contrast. To provide insights into the occurring space-charge physics in both technologies, this thesis uses analytical modeling, Monte Carlo simulations and experimental techniques. Using these …

The use of sun-induced fluorescence to remotely characterise phytoplankton dynamics
This study exploits the remotely sensed sun-induced fluorescence signal to infer phytoplankton assemblage dynamics in the southern Benguela via in situ bio-optical moorings, and through the use of satellite sensors.

Design and Implementation of the VirtuOS Operating System
… failures. VirtuOS is an operating system that exploits a new method of decomposition to protect against such failures. VirtuOS exploits virtualization to isolate and protect vertical slices of existing OS kernels in separate service domains. Each service domain represents a partition of an …

Anomaly Detection Through System and Program Behavior Modeling
… observed in the evolution of advanced modern exploits is their growing sophistication in stealthy attacks. Code-reuse attacks such as return-oriented programming allow intruders to execute mal-intended instruction sequences on a victim machine without injecting external code. Successful …

Scaling sequential code with hardware-software co-design for fine-grain speculative parallelization
… tasks to enable cheap selective aborts. SCC exploits parallelism across function calls, loops, and loop nests; performs new transformations to expose more speculative parallelism enabled by Swarm's execution model; and exploits locality across fine-grain tasks. As a result, SCC speeds up …

Differential light scattering spectroscopy measurements for detecting and imaging cancer
… scattering and diffuse reflectance. SD/LSS exploits the penetration abilities of diffuse reflectance while /LSS exploits the angular asymmetry of single backscattering from large particles. O/LSS has the added advantage of being able to isolate single backscattering specifically from …

Optimizations in stream programming for multimedia applications
… number of a target filter. This thesis also exploits the fact that multimedia applications are tolerant in the accuracy of the program output. We apply a memoization technique that exploits this tolerance and the repetitive nature of multimedia data. We provide a runtime system that …

Essays on U.S. agricultural policy : subsidies, crop insurance, and environmental auctions
… of the Conservation Reserve Program. Chapter one exploits exogenous variation in agricultural subsidies to measure the effects on farmland rental rates. The primary finding is that landlords capture one-fifth of the marginal subsidy dollar per acre. This finding stands in contrast to the standard …
