Physical media (like surveillance cameras) and social media (like Instagram and Twitter) may both be useful in attaining on-the-ground information during an emergency or disaster situation. However, the intersection and reliability of both surveillance cameras and social media during a natural disaster are not fully understood. To address this gap, we tested whether social media is of utility when physical surveillance cameras went off-line during Hurricane Irma in 2017. Specifically, we collected and compared geo-tagged Instagram and Twitter posts in the state of Florida during times and in areas where public surveillance cameras went off-line. We report social media content …

Study Of Physical Layer Security And Teaching Methods In Wireless Communications, Zhijian Xie, Christopher Horne Oct 2018

Study Of Physical Layer Security And Teaching Methods In Wireless Communications, Zhijian Xie, Christopher Horne

KSU Proceedings on Cybersecurity Education, Research and Practice

In most wireless channels, the signals propagate in all directions. For the communication between Alice and Bob, an Eavesdropper can receive the signals from both Alice and Bob as far as the Eavesdropper is in the range determined by the transmitting power. Through phased array antenna with beam tracking circuits or cooperative iteration, the signals are confined near the straight line connecting the positions of Alice and Bob, so it will largely reduce the valid placement of an Eavesdropper. Sometimes, this reduction can be prohibitive for Eavesdropper to wiretap the channel since the reduced space can be readily protected. Two …

Bipartite Quantum Interactions: Entangling And Information Processing Abilities, Siddhartha Das Oct 2018

Bipartite Quantum Interactions: Entangling And Information Processing Abilities, Siddhartha Das

LSU Doctoral Dissertations

The aim of this thesis is to advance the theory behind quantum information processing tasks, by deriving fundamental limits on bipartite quantum interactions and dynamics. A bipartite quantum interaction corresponds to an underlying Hamiltonian that governs the physical transformation of a two-body open quantum system. Under such an interaction, the physical transformation of a bipartite quantum system is considered in the presence of a bath, which may be inaccessible to an observer. The goal is to determine entangling abilities of such arbitrary bipartite quantum interactions. Doing so provides fundamental limitations on information processing tasks, including entanglement distillation and secret key …


Liboblivious: A C++ Library For Oblivious Data Structures And Algorithms, Scott D. Constable, Steve Chapin Oct 2018

Liboblivious: A C++ Library For Oblivious Data Structures And Algorithms, Scott D. Constable, Steve Chapin

Electrical Engineering and Computer Science - Technical Reports

Infrastructure as a service (IaaS) is an enormously beneficial model for centralized data computation and storage. Yet, existing network-layer and hardware-layer security protections do not address a broad category of vulnerabilities known as side-channel attacks. Over the past several years, numerous techniques have been proposed at all layers of the software/hardware stack to prevent the inadvertent leakage of sensitive data. This report discusses a new technique which integrates seamlessly with C++ programs. We introduce a library, libOblivious, which provides thin wrappers around existing C++ standard template library classes, endowing them with the property of memory-trace obliviousness.

Fingerprinting Jpegs With Optimised Huffman Tables, Sean Mckeown, Gordon Russell, Petra Leimich

Journal of Digital Forensics, Security and Law

A common task in digital forensics investigations is to identify known contraband images. This is typically achieved by calculating a cryptographic digest, using hashing algorithms such as SHA256, for each image on a given medium, and comparing individual digests with a database of known contraband. However, the large capacities of modern storage media and time pressures placed on forensics examiners necessitates the development of more efficient processing methods. This work describes a technique for fingerprinting JPEGs with optimised Huffman tables which requires only the image header to be present on the media. Such fingerprints are shown to be robust across …

Hawkeye: Towards A Desired Directed Grey-Box Fuzzer, Hongxu Chen, Yinxing Xue, Yuekang Li, Bihuan Chen, Xiaofei Xie, Xiuheng Wu, Yang Liu

Research Collection School Of Computing and Information Systems

Grey-box fuzzing is a practically effective approach to test real-world programs. However, most existing grey-box fuzzers lack directedness, i.e. the capability of executing towards user-specified target sites in the program. To emphasize existing challenges in directed fuzzing, we propose Hawkeye to feature four desired properties of directed grey-box fuzzers. Owing to a novel static analysis on the program under test and the target sites, Hawkeye precisely collects the information such as the call graph, function and basic block level distances to the targets. During fuzzing, Hawkeye evaluates exercised seeds based on both static information and the execution traces to generate …

Initializing Trust In Smart Devices Via Presence Attestation, Xuhua Ding, Gene Tsudik

Research Collection School Of Computing and Information Systems

Many personal computing and more specialized (e.g., high-end IoT) devices are now equipped with sophisticated processors that only a few years ago were present only on high-end desktops and servers. Such processors often include an important hardware security component in the form of a DRTM (Dynamic Root of Trust for Measurement) which initiates trust and resists software (and even some physical) attacks. However, despite substantial prior research on trust establishment with secure hardware, DRTM security was always considered without any involvement of the human user, who represents a vital missing link. This prompts an important challenge: how can a user …
