Information leaks and information systems.
While the rise of WikiLeaks and other leak-related organizations has been reflected in the research in international relations, it has received limited focus within the field of information systems. This study surveyed current college students in order to understand what factors may play a role in …

Preventing information leaks with policy-agnostic programming
As a solution to the problem of information leaks, I propose a policy-agnostic programming paradigm that enforces security and privacy policies by construction. I present the implementation of this paradigm in a new language, Jeeves, that automatically enforces information flow policies describing …

A monitoring framework for side-channel information leaks
… becoming an ever important field of study as the information available on these systems is of ever increasing value. The state of research on direct security attacks to computer systems, such as exploiting memory safety errors or exploiting unfiltered inputs to shells is at an advanced state and a …

Advanced Network Inference Techniques Based on Network Protocol Stack Information Leaks
Side channels are channels of implicit information flow that can be used to find out information that is not allowed to flow through explicit channels. This thesis focuses on network side channels, where information flow occurs in the TCP/IP network stack implementations of operating systems. I …

Security threats to Android apps
… (app for short) to store and handle private information. The fluidity of mobile apps and mobile app markets has complicated mobile app security. Many new threats emerged are either because of the deficiency of mobile app development or the design ambiguities of the Android operating system. …

A security evaluation of the salsa anonymous communication system
… in the M\""{o}bius framework. Next, we analyze information leaks in the lookup mechanisms of Salsa and show how these leaks can be used to compromise anonymity. We show that the techniques that are used to combat active attacks on the lookup mechanism dramatically increase information leaks and …

Mostly-static decentralized information flow control
… from sharing data usefully, or allow private information to leak. For example, security mechanisms in Java prevent many useful applications while still permitting Trojan horse applets to leak private information. This thesis describes the decentralized label model, a new model of information …

Implementation of DPA-Resistant Circuit for FPGA
… strongly reduces the power-consumption-dependent information leaks. We will show all the necessary steps needed to implement secure circuits on a FPGA, from initial design stage all the way to verification of the level of security through laboratory measurements. We show that the direct mapping of …

Information flow for secure distributed applications
Private and confidential information is increasingly stored online and increasingly being exposed due to human errors as well as malicious attacks. Information leaks threaten confidentiality, lead to lawsuits, damage enterprise reputations, and cost billion of dollars. While distributed computing …

Analysis and Enforcement of Properties in Software Systems
… time of a program and detecting side-channel information leaks. The second category is concerned with static program transformation. The goal is to eliminate side channels by equalizing the number of CPU cycles and the number of cache misses along all program paths for all sensitive variables. …

Android at risk: current threats stemming from unprotected local and external resources
… if not performed correctly, can lead to severe information leaks stemming from un- protected local and external resources. It also presents new defense solutions and mitigation strategies that successfully tackle the found vulnerabilities. In particular, this thesis unearths three new side …

Efficient Symbolic Execution of Concurrent Software
… for detecting concurrency related side-channel information leaks by analyzing the cache timing behaviors of a concurrent program in symbolic execution. This dissertation evaluates the proposed methods on a diverse set of both synthesized programs and real-world applications. The experimental …

Access and information flow control to secure mobile web service compositions in resource constrained environments
… robust mechanisms for ensuring security for such information sharing services. Common security mechanisms such as access control and information flow control are either restrictive or weak in that they prevent applications from sharing data usefully, and/or allow private information leaks when …

Three essays on financial markets
… traders' private signals and the probability of information events. The first essay's main theoretical findings are: (a) Other than the intuitive effect of incurring loss, noise in private signals may preserve informed traders' profit by dampening competition. When the noise level is relatively …
