Leveraging Bluetooth As A Second Factor In Two-Factor Authentication, Cimone Le Wright-Hamor Jan 2017

Leveraging Bluetooth As A Second Factor In Two-Factor Authentication, Cimone Le Wright-Hamor

Graduate Theses and Dissertations

Passwords have been the dominant single-factor authentication method for decades but are no longer sufficient to validate a user's identity. The simplistic nature of passwords perpetuate their existence and makes them an easy attack vector. However, Two-Factor Authentication (2FA) augments passwords and adds a layer of security. Although 2FA has the potential to increase security, traditional second factors require user interaction at every login attempt, which may contribute to slow adaptation. Traditional second factors drastically alter the user authentication experience and typically require the user to navigate away from the login screen. Therefore, we present a new second-factor method ...


An Fpga Architecture For The Recovery Of Wpa/Wpa2 Keys, Tyler Blaine Johnson Jan 2014

An Fpga Architecture For The Recovery Of Wpa/Wpa2 Keys, Tyler Blaine Johnson

Graduate Theses and Dissertations

Wi-Fi protected access (WPA) has provided serious improvements over the now deprecated wired equivalent privacy protocol (WEP). WPA, however, still has some flaws that allow an attacker to obtain the passphrase. One of these flaws is exposed when the access point (AP) is operating in the WPA personal mode. This is the most common mode as it is the quickest and easiest to configure. It requires the attacker to capture the traffic from four-way handshake between the AP and client, and then provide enough compute time to reverse the passphrase. Attackers quickly noticed that by investing the compute time in ...


Graph-Based Forensic Investigation Of Bitcoin Transactions, Chen Zhao Jan 2014

Graph-Based Forensic Investigation Of Bitcoin Transactions, Chen Zhao

Graduate Theses and Dissertations

This thesis illustrates forensic research work on Bitcoin, an innovative Internet based global transaction system that attracts ascending popularity during the recent few years. As an open, public and scalable distributed payment system, Bitcoin brings forward significant economic and technological impact to our world. Meanwhile, a new notion of virtual currency, "Bitcoin" comes into existence such that Bitcoin currency can be "mined" from all over world complying with specific algorithms. Mined bit "coins" has practical monetary values that turn the Bitcoin system into a digital currency circulation system. Due to Bitcoin's decentralized semantics, Bitcoin transaction and currency are not ...


Forensic Analysis Of Whatsapp On Android Smartphones, Neha S. Thakur Aug 2013

Forensic Analysis Of Whatsapp On Android Smartphones, Neha S. Thakur

University of New Orleans Theses and Dissertations

Android forensics has evolved over time offering significant opportunities and exciting challenges. On one hand, being an open source platform Android is giving developers the freedom to contribute to the rapid growth of the Android market whereas on the other hand Android users may not be aware of the security and privacy implications of installing these applications on their phones. Users may assume that a password-locked device protects their personal information, but applications may retain private information on devices, in ways that users might not anticipate. In this thesis we will be concentrating on one such application called 'WhatsApp', a ...


Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo Apr 2011

Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo

Faculty Scholarship at Penn Law

Cloud computing has emerged as perhaps the hottest development in information technology. Despite all of the attention that it has garnered, existing analyses focus almost exclusively on the issues that surround data privacy without exploring cloud computing’s architectural and policy implications. This article offers an initial exploratory analysis in that direction. It begins by introducing key cloud computing concepts, such as service-oriented architectures, thin clients, and virtualization, and discusses the leading delivery models and deployment strategies that are being pursued by cloud computing providers. It next analyzes the economics of cloud computing in terms of reducing costs, transforming capital ...


Jess – A Java Security Scanner For Eclipse, Russell Spitler Jan 2005

Jess – A Java Security Scanner For Eclipse, Russell Spitler

Honors Theses

Secure software is the responsibility of every developer. In order to help a developer with this responsibility there are many automated source code security auditors. These tools perform a variety of functions, from finding calls to insecure functions to poorly generated random numbers. These programs have existed for years and perform the security audit with varying degrees of success.

Largely missing in the world of programming is such a security auditor for the Java programming language. Currently, Fortify Software produces the only Java source code security auditor; this is a commercially available package.

This void is what inspired JeSS, Java ...
