Quantum Security of a Compact Multi-Signature

Cryptography
With the rapid advances in quantum computing, quantum security is now an indispensable property for any cryptographic system. In this paper, we study how to prove the security of a complex cryptographic system in the quantum random oracle model. We first

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

American Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

The equivalence of the random oracle model and the ideal cipher model, revisited [PDF]

Proceedings of the forty-third annual ACM symposium on Theory of computing, 2011
We consider the cryptographic problem of constructing an invertible random permutation from a public random function (i.e., which can be accessed by the adversary). This goal is formalized by the notion of indifferentiability of Maurer et al. (TCC 2004).

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Two improved content extraction signature schemes

网络与信息安全学报, 2017
Motivated by the idea of batch signatures,two variants of content extraction signature schemes based on commit vector and RSA respectively were presented.In the proposed schemes,the efficiency of signing and verification were improved by unifying certain

Prediction of subsequent seizures after acute symptomatic seizures in critically ill children: A clinical–electroencephalographic model

Epilepsia, EarlyView.
Abstract Objective We aimed to determine the risk of subsequent seizure or epilepsy diagnosis after acute symptomatic seizures (ASyS) in critically ill children, evaluate whether antiseizure medication (ASM) use is associated with subsequent seizure/epilepsy diagnosis, and develop a simple Seizure/Epilepsy Risk Score to predict subsequent seizure ...

Climate Risks and the Risk Premia of AI Stocks: Some Forecasting Experiments

Journal of Forecasting, EarlyView.
ABSTRACT This study examines whether physical and transition climate‐risk measures predict the risk premia of AI‐related stocks, and whether incorporating these risks improves forecast performance relative to benchmark models. The findings suggest that global transition climate shocks lower the premia of AI stocks, while US climate policy increases ...
