Practical Quantum Oblivious Transfer [PDF]

, 2007
We describe a protocol for quantum oblivious transfer, utilizing faint pulses of polarized light, by which one of two mutually distrustful parties ("Alice") transmits two one-bit messages in such a way that the other party ("Bob") can choose which message he gets but cannot obtain information about both messages (he will learn his chosen bit's value ...

Reshaping the Social Contract? A Systematic Literature Review of Two Decades of Research on the Digital Welfare State in Developing Countries

Social Policy &Administration, EarlyView.
ABSTRACT The rapid digitization of welfare states is a global phenomenon, yet its impacts in developing countries, where inequalities and weak infrastructure persist, are poorly understood. This systematic review synthesizes evidence on the implementation of digital welfare systems in developing countries and their effects on social inclusion and ...

Oblivis: A Framework for Delegated and Efficient Oblivious Transfer

Proceedings on Privacy Enhancing Technologies
As database deployments shift toward cloud platforms and edge devices, thin clients need to securely retrieve sensitive records without leaking their query intent or metadata to the proxies that mediate access. Oblivious Transfer (OT) is a core tool for private retrieval, yet existing OTs assume direct client–database interaction and lack support for ...

Animal Segregation: The Biopolitics of Concentrated Pig Farming

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract This paper explores the possibility to think through the concept of animal segregation to understand the more‐than‐human geographies of livestock animals. By redirecting the analytical tools for studying the spatial separation of humans to the segregation of animals, this paper contributes to understanding the geographical processes of ...

The Long Shadow of Karl Weierstraß Over the Calculus of Variations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.

Fast Contract Signing with Batch Oblivious Transfer [PDF]

, 2020
. Oblivious transfer protocol is a basic building block of various cryptographic constructions. We propose a novel protocol -batch oblivious transfer. It allows efficient computation of multiple instances of oblivious transfer protocols.

Why Some Critical Junctures Lead Nowhere: Exploring Dynamic and Static Policy Paths

Governance, Volume 39, Issue 4, December 2026.
ABSTRACT Some critical junctures fail to cause significant change in practice. Inspired by historical institutionalism, this article develops the concept of dynamic and static policy paths to explain why some critical junctures do not lead to change, while others do.

Simulatable Adaptive Oblivious Transfer [PDF]

, 2007
We study an adaptivevariant of oblivious transfer in which a sender has Nmessages, of which a receiver can adaptively choose to receive kone-after-the-other, in such a way that (a) the sender learns nothing about the receiver's selections, and (b) the receiver only learns about the krequested messages.

Lightweight oblivious transfer extensions

, 2016
Η ασφαλής πολυκομματική υπολογιστική (Secure Multiparty Computation) (MPC) δημιουργήθηκε από τον A. Yao το 1962. Παρόλο που τότε αποτελούσε μόνο ένα θεωρητικό πρόβλημα, σήμερα, λόγω του Υπολογιστικού Νέφους (Cloud Computing) το οποίο είναι η νέα μόδα ...
