Blockchain Certificateless Encryption Mechanism Based on National Secret Algorithm [PDF]

Jisuanji kexue
The blockchain has attracted widespread attention because of its distributed,non-tamperable and inherent immutability features.However,the international cryptographic algorithm used in the blockchain has certain backdoor security risks.Based on the ...

Revocable Certificateless Public Key Encryption With Outsourced Semi-Trusted Cloud Revocation Agent

IEEE Access, 2020
Certificateless public key cryptography (CL-PKC) not only eliminates the need for certificates in traditional certificate-based PKC but also solves the inherent key escrow problem in identity-based PKC.

Non-malleable codes for space-bounded tampering [PDF]

, 2017
Non-malleable codes—introduced by Dziembowski, Pietrzak and Wichs at ICS 2010—are key-less coding schemes in which mauling attempts to an encoding of a given message, w.r.t.

Riemannian Geometry for the Classification of Brain States with Intracortical Brain Recordings

Advanced Intelligent Systems, EarlyView.
Geometric machine learning is applied to decode brain states from invasive intracortical neural recordings, extending Riemannian methods to the invasive regime where data is scarcer and less stationary. A Minimum Distance to Mean classifier on covariance manifolds uses geodesic distances to outperform convolutional neural networks while reducing ...

Does Accounting Scope 3 Emissions Improve Sustainable Business Outcomes? Evidence From the S&P 500 Technology Companies

Business Strategy and the Environment, EarlyView.
ABSTRACT Corporate sustainability efforts increasingly emphasize Scope 3 emissions due to their substantial share of total corporate carbon footprints. However, reporting these emissions remains inconsistent, limiting transparency and comparability across firms.
