A Weakness in Some Oblivious Transfer and Zero-Knowledge Protocols [PDF]

, 2006
We consider oblivious transfer protocols and their applications that use underneath semantically secure homomorphic encryption scheme (e.g. Paillier's). We show that some oblivious transfer protocols and their derivatives such as private matching,

Oblivis: A Framework for Delegated and Efficient Oblivious Transfer

CoRR
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 ...

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Device-independent oblivious transfer from the bounded-quantum-storage-model and computational assumptions

New Journal of Physics, 2023
We present a device-independent protocol for oblivious transfer (DIOT) and analyse its security under the assumption that the receiver’s quantum storage is bounded during protocol execution and that the device behaves independently and identically in ...

Routine Dynamics at a Cardiac First‐Aid Unit: How Context, Emotions, and Identities Drive the Adaptation of Action Patterns

Journal of Management Studies, EarlyView.
Abstract Emotions are a catalyst for actions. They are therefore important for developing an understanding of organizational routines as generative patterns of interdependent actions. To investigate how the performances and action patterns of routines are impacted by emotion changes brought about by alterations in the context of routine enactment, we ...

Autofiction as relational mediation: A Ghost in the Throat and To Write as if Already Dead

Orbis Litterarum, EarlyView.
Abstract Because of its exploration of the self and the resemblance to online styles of publishing, autofiction has been accused by certain scholars of reflecting neoliberal tendencies. Hans Demeyer and Sven Vitse have developed a more nuanced view on the relation between autofiction and neoliberalism.

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 ...

The Ideology of History and the Limits of Cinematic Realism in Andrei Zviagintsev’s Leviathan and Nataliia Meshchaninova’s The Hope Factory

The Russian Review, EarlyView.
Abstract This article brings together theories of history and filmic realism to analyze the representation of the provinces in Nataliia Meshchaninova’s The Hope Factory (Kombinat “Nadezhda,” 2014) and Andrei Zviagintsev’s Leviathan (Leviafan, 2014). It argues that these two films share a typically realist attitude of respect toward the profilmic in ...

Spacetime-constrained oblivious transfer

, 2016
In 1-out-of-2 oblivious transfer (OT), Alice inputs numbers x0,x1, Bob inputs a bit b and outputs xb. Secure OT requires that Alice and Bob learn nothing about b and xb, respectively.
