An ID-based multi-signer universal designated multi-verifier signature scheme

, 2011
In an ID-based universal designated verifier signature scheme, a single signer generates a signature that can only be verified by a designated verifier using a simplified public identity such as an e-mail address. In this paper, we expand the scheme to a

Geopolitics and global strategy: Making money under anarchy

Global Strategy Journal, EarlyView.
Abstract Research Summary Multinational firms conduct cross‐border trade and investment in a world of anarchy, where nation‐states must secure their survival in the absence of a world government. We develop a geopolitical‐economic order (GEO) framework to argue that the extent of geopolitical competition incentivizes states to create one of two types ...

Universal Anti-forensics Attack against Image Forgery Detection via Multi-modal Guidance

CoRR
The rapid advancement of AI-Generated Content (AIGC) technologies poses significant challenges for authenticity assessment. However, existing evaluation protocols largely overlook anti-forensics attack, failing to ensure the comprehensive robustness of state-of-the-art AIGC detectors in real-world applications.

Millennials' Hybrid Consumer Identities: Balancing Consumer Ethnocentrism

Psychology &Marketing, EarlyView.
ABSTRACT While consumer ethnocentrism has been widely examined, little is known about how consumers manage the persistent gap between ethnocentric attitudes and everyday purchasing behavior. Drawing on balance theory (Heider 1958), this study conceptualizes consumer ethnocentrism as a situationally activated balancing process rather than a stable ...

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

Materials Genome Engineering Advances, EarlyView.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...
