Investigating Information Structure Of Phishing Emails Based On Persuasive Communication Perspective, Ki J. Lee, Il-Yeol Song

Journal of Digital Forensics, Security and Law

Current approaches of phishing filters depend on classifying messages based on textually discernable features such as IP-based URLs or domain names as those features that can be easily extracted from a given phishing message. However, in the same sense, those easily perceptible features can be easily manipulated by sophisticated phishers. Therefore, it is important that universal patterns of phishing messages should be identified for feature extraction to serve as a basis for text classification. In this paper, we demonstrate that user perception regarding phishing message can be identified in central and peripheral routes of information processing. We also present a …

Education Organization Baseline Control Protection And Trusted Level Security, Wasim A. Al-Hamdani

Journal of Digital Forensics, Security and Law

Many education organizations have adopted for security the enterprise best practices for implementation on their campuses, while others focus on ISO Standard (or/and) the National Institution of Standards and Technology.

All these adoptions are dependent on IT personal and their experiences or knowledge of the standard. On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when …

Promoting a change in Database Curriculum Development trends may also play a role …

Evolving Players For An Ancient Game: Hnefatafl, Philip Hingston

Research outputs pre 2011

Hnefatafl is an ancient Norse game - an ancestor of chess. In this paper, we report on the development of computer players for this game. In the spirit of Blondie24, we evolve neural networks as board evaluation functions for different versions of the game. An unusual aspect of this game is that there is no general agreement on the rules: it is no longer much played, and game historians attempt to infer the rules from scraps of historical texts, with ambiguities often resolved on gut feeling as to what the rules must have been in order to achieve a balanced …

Experiments With Monte Carlo Othello, Philip Hingston, Martin Masek

Research outputs pre 2011

In this paper, we report on our experiments with using Monte Carlo simulation (specifically the UCT algorithm) as the basis for an Othello playing program. Monte Carlo methods have been used for other games in the past, most recently and notably in successful Go playing programs. We show that Monte Carlo-based players have potential for Othello, and that evolutionary algorithms can be used to improve their strength.

Use Of Online Tools To Aid Group Work, Martin Masek

Research outputs pre 2011

In this paper we examine the use of online tools – namely wikis and blogs in aiding group work for a large and diverse student-based team. The results suggest that while students see the generic skill of being able to work in a team as important for their future career, using blogs and wikis is not seen to be as important. It was also found that the flexibility of these tools provides more motivation for students than having assessment based on their use.

A Gui For The Deaf-Blind: An Additional Concepts Paper, David Veal

Research outputs pre 2011

People with some residual vision though still classified as blind may be able to read on screen patterns presented via a computer program whereby such a pattern can represent a textual character and a presentation of sequences of such patterns can represent words. These patterns can be adjusted to utilize the user’s remaining vision capacity. Previous research has shown that volunteers who where legally classified as blind could read simple sentences via such a system. This system is known as the Dynamic Pattern System (DPS) and is a test bed for research. Although this research involved a single pattern represented …

Experimental Demonstration Of A Dynamic 10gbit/S Wdm Header/Label Recognition Structure, Muhsen Aljada, Kamal Alameh, Byeong Ha Lee, Yong Tak Lee, Kiegon Im, Se-Jong Baik

Research outputs pre 2011

In this paper, we experimentally demonstrate a dynamic wavelength-division-multiplexing (WDM) header/label recognition structure that processes on-the-fly WDM patterns. An opto-VLSI processor is used to dynamically generate digital phase holograms that control the wavelength components of the label/header to create digital wavelength profiles. An autocorrelation function of a high-peak is generated when a label bit pattern matches a digital wavelength profile. The main attractive feature of using an opto-VLSI processor is that the lookup table of matching digital wavelength profiles does not need modification when the data bit-rate is upgraded. The dynamic pattern recognition structure is experimentally demonstrated at 10 Gbit/s …

Experimental Demonstration Of A Tunable Laser Using An Soa And An Opto-Vlsi Processor, Muhsen Aljada, Rong Zheng, Kamal Alameh, Yong Lee

Research outputs pre 2011

In this paper we propose and experimentally demonstrate a tunable laser structure cascading a semiconductor optical amplifier (SOA) that generates broadband amplified spontaneous emission and a reflective Opto-VLSI processor that dynamically reflects arbitrarily wavelengths and injects them back into the SOA, thus synthesizing an output signal of variable wavelength. The wavelength tunablility is performed using digital phase holograms uploaded on the Opto-VLSI processor. Experimental results demonstrate a tuning range from 1524nm to 1534nm, and show that the proposed tunable laser structure has a stable performance.

Pervasive 2d Barcodes For Camera Phone Applications, Hiroko Kato, Keng T. Tan

Research outputs pre 2011

In a previous study, we evaluated six 2D barcodes using eight criteria for standardization potential: omnidirectional symbol reading, support for low-resolution cameras, reading robustness under different lighting conditions, barcode reading distance, error correction capability, security, support for multiple character sets, and data capacity. We also considered the fidelity of the camera phone's captured image as a metric for gauging reading reliability. Here, we review the six 2D barcodes and then use an additional metric - a first-read rate - to quantitatively verify our earlier results and better gauge reading reliability.

State Model Diagrams As A Pedagogical Tool - An International Evaluation, Stanislaw Maj, David Veal

Research outputs pre 2011

State model diagrams (SMDs) have been successfully used as the pedagogical foundation of network technology curriculum. SMDs selectively integrate relevant output from network devices by means of tables. SMDs are modular and hierarchical, thereby providing top-down decomposition by means of levelling, allowing a complex network to be partitioned or structured into independent units of an amenable size so that the entire system can be more easily understood. An overview of the entire network or increasing levels of detail may be obtained while maintaining links and interfaces between the different levels. Furthermore, SMDs allow technical detail to be introduced in an …

The findings contribute to the debate of standardization versus adaptation of international advertising.

Supporting Data-Intensive Wireless Sensor Applications Using Smart Data Fragmentation And Buffer Management, Mbonisi Masilela

Theses and Dissertations

Recent advances in low power device technology have led to the development of smaller powerful sensors geared for use in Wireless Sensor Networks. Some of these sensors are capable of producing large data packets in a single reading. This becomes a challenging problem given the constraints imposed by current MAC and Transport Layer implementations since a single data packet can exceed the MTU of the protocol stack. Little has been done in the way of addressing this issue in Wireless Sensor Networks. This paper proposes a novel solution to this issue. Proposed is a Lightweight Data Transportation Protocol that uses …

Xml Integrated Environment For Service-Oriented Data Management, Marwan Younes Maarouf

Browse all Theses and Dissertations

The proliferation of XML as a family of related standards including a markup language (XML), formatting semantics (XSL style sheets), a linking syntax (XLINK), and appropriate data schema standards have emerged as a de facto standard for encoding and sharing data between various applications. XML is designed to be simple, easily parsed and self-describing. XML is based on and support the idea of separation of concerns: information content is separated from information rendering, and relationships between data elements are provided via simple nesting and references. As the XML content grows, the ability to handle schemaless XML documents becomes more critical …

Unilateral and bilateral finlines including practical parameters, such as metallization thickness and grooves' depths, have been investigated. The effect of these two parameters have been discussed based on realistic configurations and the results show that, at higher frequencies, the grooves …

Application-Specific Reliable Data Transfer In Wireless Sensor Networks, Damayanti Datta

LSU Doctoral Dissertations

A wireless sensor network (WSN) is a collection of sensor nodes and base stations connected via wireless medium. It sends data collected from the nodes to the base stations for generating information. The size and low cost of the sensor nodes as well as the WSN's ability to connect without wired links are its key advantages which enable it to be deployed in hostile or inaccessible environments at low cost. However, WSNs suffer from high data loss due to the inherent weaknesses in a wireless transmission medium, transmission problems in hostile environments due to human interference, etc. and node failures …

Optimal Layout Of Multicast Groups Using Network Embedded Multicast Security In Ad Hoc Sensor Networks, Richard R. Brooks, Brijesh Pillai, Michele C. Weigle, Matthew Pirretti

Computer Science Faculty Publications

This paper considers the security of sensor network applications. Our approach creates multicast regions that use symmetric key cryptography for communications. Each multicast region contains a single keyserver that is used to perform key management and maintain the integrity of a multicast region. Communications between two multicast regions is performed by nodes that belong to both regions. To ease the network management burden, it is desirable for the networks to self-organize into regions and dynamically select their keyservers. This paper shows how to determine the number of keyservers (k) to use and the size in the number of hops (h) …

How Much Preservation Do I Get If I Do Absolutely Nothing? Using The Web Infrastructure For Digital Preservation, Martin Klein, Frank Mccown, Joan A. Smith, Michael Nelson

Computer Science Faculty Publications

To date, most of the focus regarding digital preservation has been on removing copies of the resources to be preserved from the “living web” and placing them in an archive for controlled curation. Once inside an archive, the resources are subject to careful processes of refreshing (making additional copies to new media) and migrating (conversion to new formats and applications). For small numbers of resources of known value, this is a practical and worthwhile approach to digital preservation. However, due to the infrastructure costs (storage, networks, machines) and more importantly the human management costs, this approach is unsuitable for web …

Directflow: A Domain-Specific Language For Information-Flow Systems, Andrew P. Black, Chuan-Kai Lin

Computer Science Faculty Publications and Presentations

Programs that process streams of information are commonly built by assembling reusable information-flow components. In some systems the components must be chosen from a pre-defined set of primitives; in others the programmer can create new custom components using a general-purpose programming language. Neither approach is ideal: restricting programmers to a set of primitive components limits the expressivity of the system, while allowing programmers to define new components in a general-purpose language makes it difficult or impossible to reason about the composite system. We advocate defining information-flow components in a domain-specific language (DSL) that enables us to infer the properties of …
