Provably Secure MACs from Differentially-Uniform Permutations and AES-Based

, 2006
. We propose message authentication codes (MACs) that combine a block cipher and an additional (keyed or unkeyed) permutation. Our MACs are provably secure if the block cipher is pseudorandom and the additional permutation has a small differential ...

Low‐Carbon Energy Transition and Corporate Carbon Emissions: The Critical Role of Climate Change Mitigation Policies and Institutional Context

Business Strategy and the Environment, EarlyView.
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 ...

Two Practical and Provably Secure Block Ciphers: BEAR and LION

, 1996
In this paper we suggest two new provably secure block ciphers, called BEAR and LION. They both have large block sizes, and are based on the Luby-Rackoff construction.

From Text to Value: Measuring and Pricing Firm Climate Risk Exposure

Business Strategy and the Environment, EarlyView.
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 ...

Environmental Management Accounting in Private Hospitals: Navigating Competing Strategic Priorities for Sustainable Decision‐Making

Business Strategy and the Environment, EarlyView.
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 ...

Efficient identification protocol provably secure in standard model

Tongxin xuebao, 2009
Based on the hardness assumption of the collusion attack algorithm with k traitors （K-CAA） in a gap Diffie-Hellman （GDH） group, a new and efficient identification protocol is proposed.
