Limits of Provable Security for Homomorphic Encryption [PDF]
We show that public-key bit encryption schemes which support weak (i.e., compact) homomorphic evaluation of any sufficiently “sensitive” collection of functions cannot be proved message indistinguishable beyond AM ∩ coAM via general (adaptive) reductions, and beyond statistical zero-knowledge via reductions of constant query complexity.

Provable security of internet protocols [PDF]
Secure communications over the Internet are typically established by first running an authenticated key exchange protocol, which computes a secret key between two users, which is then utilised in an encryption protocol.

ABSTRACT This study examines the strategic efficacy of corporate low‐carbon energy transition, such as through nuclear energy adoption, as a response to decarbonization pressures. Analyzing an international sample of energy firms, we demonstrate that the relationship between this form of transition and emission reductions is not technologically ...

From Text to Value: Measuring and Pricing Firm Climate Risk Exposure
ABSTRACT We examine how the prominence and tone of climate risk disclosures affect firm value and strategic climate positioning for large European nonfinancial companies. We developed a firm‐level climate risk exposure (CRE) index that assesses climate risks within corporate narratives across four EU categories: transition risk, physical risk ...

ABSTRACT Environmental management accounting (EMA) is increasingly recognised as essential for carbon governance, accountability and net zero transitions, yet research has overlooked how sustainability is negotiated within mission‐driven but commercially exposed service organisations such as private hospitals in developing economies, a sector often ...

ABSTRACT This study examines how circular economy (CE) practices relate to supply chain resilience (SCRES), focusing on the capability‐based mechanisms through which CE strategies may influence resilience outcomes. Drawing on survey data from 125 Italian firms engaged in CE initiatives, we employ partial least squares structural equation modelling (PLS‐

Provable Security in Cryptography [PDF]
These lecture notes are a compilation of some of my readings while I was preparing two lectures given at EPFL on provable security in cryptography. They are essentially based on a book chapter from David Pointcheval called “Provable Security for Public ...

Can Credit Rating Changes Affect Corporate Carbon Emissions? Some Evidence From the S&P 500
ABSTRACT Using panel data on US S&P 500 firms from 2012 to 2024, this study examines how credit rating changes affect corporate carbon performance. Drawing on the resource‐based view and prospect theory, we show that credit rating downgrades lead to a statistically and economically significant deterioration in emission reduction scores.
