Trustworthy, Privacy-Preserving, and Functional Data Outsourcing Systems
Le, Thanh Tung (Virginia Tech, 2026-04-03)
Data outsourcing systems, e.g., Dropbox, Google Drive, and iCloud have become essential in our daily lives. They can reduce the storage burden on user devices, which have limited storage capacity. Also, they serve as backup places for user data to prevent data loss due to hardware failures. However, data misuse and breaches remain serious concerns. Even when the cloud provider is trusted, attacks on storage servers have exposed user data, threatening user privacy and the reputation of corporations. This dissertation develops and implements trustworthy, privacy-preserving, and functional data outsourcing systems. The contributions consist of two pieces. First, we design and implement a Proof of Retrievability scheme named Porla, an efficient technique allowing the user to audit their data to ensure its intactness. Our work features an optimal audit-proof size and low end-to-end audit latency in comparison with prior work. Second, we develop a series of novel searchable encryption techniques achieving high security guarantees and performance in various threat and system models. In particular, we start by designing new schemes for multi-user searchable encryption, MAPLE and MUSES, using state-of-the-art cryptographic tools and emerging distributed computation algorithms. Our MAPLE and MUSES offer high security guarantees while optimizing search complexity in terms of computation and communication costs. However, they rely on distributed computation for secure search, which incur expensive deployment and maintenance cost. Therefore, we turn our direction to deal with the security and performance issues in public-key searchable encryption (PKSE) and hybrid searchable encryption (HSE), which can support multi-user settings in practice more naturally, such as email and messaging systems. To this end, we design Hermes, which simultaneous resolves many open problems in PKSE/HSE settings, including preventing keyword-guessing attacks, achieving user-efficient epoch-based forward privacy, and optimizing server computation cost for keyword search. Finally, we observe that mitigating pattern leakages in PKSE/HSE has remained an open and unexplored research problem. Applying differential privacy (DP) is a potential approach as it achieves single-round search and small user-side storage, but the state-of-the-art work using DP still suffers from significant overhead to be applicable for practical applications. Our final work FROST devises a new approach for applying DP in encrypted search, showing a significant advance in terms of performance and communication cost. All the aspects addressed in this dissertation are essential for building practical encrypted data outsourcing systems that achieve both high performance and strong security guarantees.
Jasmine Center: Home Away From Home Home As Memory, Identity, And Light In The Heart Of Washington, DC
Fatima, Anosha (Virginia Tech, 2026-04-02)
HOME AWAY FROM HOME
Home as Memory, Identity, and Light in the Heart of Washington, DC Anosha Fatima The thesis examines the concept of home not merely as a physical structure, but as a deeply felt experience. Home is conceived as something that goes beyond the boundaries of the actual building and is influenced by elements such as memory, emotion, and culture.
The thesis further explores the role of architecture as an element that defines the experience of home. Architecture is seen here as a platform through which identity, tradition, and community can be made visible and accessible.
Through the integration of theatre as a place of cultural performance, a restaurant as a location of hospitality, and open courtyards as gathering places, the thesis showcases how architectural design can be used to encourage interaction between different groups of people. Through the integration of these programmatic elements, the thesis aims to create a space that not only encourages interaction but also a space that allows a community to be seen and represented.
Postal Intelligence: The Tassis Family and Communications Revolution in Early Modern Europe
Midura, Rachel (Cornell University Press, 2025-03)
Postal Intelligence connects and situates histories of the post and government intelligence alongside print technology and state power in the wider context of the early modern communications revolution. In the sixteenth century, postal services became central to domestic governance and foreign policy enterprises, extended government reach and surveillance, and offered new control over the public sphere.
Rachel Midura focuses on the Tassis family, members of which served as official postmasters to the dukes of Milan, the pope, Spanish kings, and Holy Roman emperors. Using administrative records and family correspondence, she follows the Tassis family, their agents, and their rivals as their influence expanded from northern Italy across Europe. Postal Intelligence shows how postmasters and postmistresses were key players in early modern diplomacy, commerce, and journalism, whose ultimate success depended on both administrative ingenuity and strategic ambiguity.
Every American an Innovator: How Innovation Became a Way of Life
Wisnioski, Matthew (MIT Press, 2025)
For half a century, innovation served as a universal good in an age of fracture. That consensus is cracking. While the imperative to innovate for a better future continues to fuel systemic change around the world, critics now assail innovation culture as an engine of inequality or accuse its do-gooders of woke groupthink. What happened? Drawing on a decade of research, Every American an Innovator by Matthew Wisnioski investigates how innovation—a once obscure academic term—became ingrained in our institutions, our education, and our beliefs about ourselves.
Wisnioski argues that innovation culture did not spring from the digital revolution, nor can it be boiled down to heroic entrepreneurs or villainous capitalists. Instead, he reveals the central role of a new class of experts in spreading toolkits and mindsets from the cornfields of 1940s Iowa to Silicon Valley tech giants today. This group of engineers, philosophers, bureaucrats, and business leaders posited that “innovators” were society’s most important change agents and remade the nation in their image. The innovation culture they built transcended partisan divisions and made strange bedfellows. Wisnioski shows how Kennedy-era policymakers inspired President Nixon’s dream of a Nobel Prize for innovators, how anti-military professors built the first university incubators for entrepreneurs, how radical feminists became millionaire consultants, how demands for a rust belt manufacturing renaissance inspired theories of a global creative class, how programs that encouraged girls and minority children to pursue innovative lives changed the nature of childhood play, and why the innovation consensus is now in dispute.
The Center for Refugee, Migrant, and Displacement Studies: Working at the Intersection of Gender and Education
Shadle, Brett L.; Hand, Deirdre; Paruar, Awil Agot (Virginia Tech, 2026-03-26)
CRMDS Director Brett Shadle will explore the work of the Center, in particular our focus on refugee and migrant education – in Virginia, across the US, and globally. Our partnership with Elimisha Kakuma, a college-access and college-prep program in Kakuma refuge camp, Kenya, will be highlighted by CRMDS Community Engagement Specialist and EK co-founder Deirdre Hand. We will then hear from EK student and incoming VT undergraduate Awel Agot Paruar about her perseverance in overcoming the challenges she faces as a refugee woman to access education.
