Conference: American Academy of Forensic Sciences 76th Anniversary Scientific Conference Abstract: In digital forensics, file system analysis is a precursor task to event reconstruction. Often, unallocated content within a file system is content of interest to an investigation, and thus recognition, extraction, and ascription of unallocated files are typical intermediary steps en route to interpr...

Conference: 10th International Conference on HCI in Business, Government and Organizations (HCIBGO) Abstract: The goal of organizational security awareness programs is to positively influence employee security behaviors. However, organizations may struggle to determine program effectiveness, often relying on training policy compliance metrics (e.g., training completion rates) rather than measuring actual im...

Conference: 15th International Conference on Social Computing and Social Media (SCSM 2023) Abstract: Encountering or engaging in risky online behavior is an inherent aspect of being an online user. In particular, youth are vulnerable to such risky behavior, making it important to know how they understand and think about this risk-taking behavior. Similarly, with parents being some of the first and...

Conference: 25th International Conference on Human-Computer Interaction Abstract: Many professional domains require the collection and use of personal data. Protecting systems and data is a major concern in these settings, making it necessary that workers who interact with personal data understand and practice good security and privacy habits. However, to date, there has been lit...

Conference: 5th International Conference on HCI for Cybersecurity, Privacy and Trust Abstract: Unsupported smart home devices can pose serious safety and security issues for consumers. However, unpatched and vulnerable devices may remain connected because consumers may not be alerted that their devices are no longer supported or do not understand the implications of using unsupported devices....

Journal: Quantum: The Open Journal for Quantum Science Abstract: We introduce a framework for graphical security proofs in device-independent quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more accessible, facilitate the discovery of...

Conference: Fourteenth Symposium on Usable Privacy and Security (SOUPS 2018) Abstract: Cryptography is an essential component of modern computing. Unfortunately, implementing cryptography correctly is a non-trivial undertaking. Past studies have supported this observation by revealing a multitude of errors and developer pitfalls in the cryptographic implementations of software product...

Abstract: We introduce a framework for graphical security proofs in device-independent quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more accessible, facilitate the discovery of...

Conference: NDSS Symposium 2017 Abstract: Online security experiences, perceptions, and behaviors are key to understanding users security practices. Users express that they are concerned about online security, but they also express frustration in navigating the often confusing and mentally taxing cybersecurity world. Thi...

Conference: 20th International Symposium on Fundamentals of Computation Theory (FCT 2015) Abstract: We study the relationship between two measures of Boolean functions; "algebraic thickness" and "normality". For a function f, the algebraic thickness is a variant of the "sparsity", the number of nonzero coefficients in the unique F_2 polynomial representing f, and the normality is the largest dimen...

Conference: 3rd International Conference on Human Aspects of Information Security, Privacy and Trust Abstract: Password management is the ubiquitous struggle of the modern human. Despite usability playing a vital role in authentication, many password policies and requirements focus on security without sufficient consideration of human factors. In fact, security and usability needs are often in contention. Un...

Conference: 3rd International Conference on Human Aspects of Information Security, Privacy and Trust Abstract: The current work examines subjective password usability across platforms—desktop, smartphone, and tablet—using system-generated passwords that adhere to the stricter password requirements found in higher-security enterprise environments. This research builds upon a series of studies at the United St...

Conference: 3rd International Conference on Human Aspects of Information Security, Privacy and Trust Abstract: Password policies – documents which regulate how users must create, manage, and change their passwords – can have complex and unforeseen consequences on organizational security. Since these policies regulate user behavior, users must be clear as to what is expected of them. Unfortunately, current po...

Conference: 3rd International Conference on Human Aspects of Information Security, Privacy and Trust Abstract: Organizations establish policies on how employees should generate, maintain, and use passwords to authenticate and gain access to the organization’s information systems. This paper focuses on employees’ attitudes towards organizational password policies and examines the impacts on their work-related...

Conference: 3rd International Conference on Human Aspects of Information Security, Privacy and Trust Abstract: We live in a world where the flow of electronic information and communication has become a ubiquitous part of our everyday life. While our lives are enhanced in many ways, we also experience a myriad of challenges especially to our privacy and security. Survey data shows that the majority of people...

Conference: 6th International Workshop on Post-Quantum Cryptography (PQCrypto 2014) Abstract: Recently, several promising approaches have been proposed to reduce keysizes for code based cryptography using structured, but non-algebraic codes, such as quasi-cyclic (QC) Moderate Density Parity Check (MDPC) codes. Biasi et al. propose further reducing the keysizes of code-based schemes using cyc...

Conference: 6th International Workshop on Post-Quantum Cryptography (PQCrypto 2014) Abstract: Historically, multivariate public key cryptography has been less than successful at offering encryption schemes which are both secure and efficient. At PQCRYPTO '13 in Limoges, Tao, Diene, Tang, and Ding introduced a promising new multivariate encryption algorithm based on a fundamentally new idea:...
