BEANIE – A 32-bit Cipher for Cryptographic Mitigations Against Software Attacks

IACR Transactions on Symmetric Cryptology
In modern CPU architectures, various security features to mitigate software attacks can be found. Examples of such features are logical isolation, memory tagging or shadow stacks. Basing such features on cryptographic isolation instead of logical checks

Recognized and Realigned: A Veteran Teacher's Moves to Leverage Familiar Forms of Epistemic Agency While Using Next Generation Science Standard Inspired Materials

Science Education, EarlyView.
ABSTRACT For 3 days, Amy, a veteran middle school science teacher, struggled to engage students in using Next Generation Science Standards (NGSS)‐aligned curriculum designed to facilitate scientific argumentation. Amy consistently used productive framing bids or cues to redirect students from “doing school” toward sensemaking and “doing science ...

Operationalising Circular Economy Through Social Innovation: A Systems Thinking‐Based Model for Sustainability Transitions

Sustainable Development, EarlyView.
ABSTRACT Social innovation (SI) is increasingly recognised as an important enabler of circular economy (CE) transitions. However, existing research offers limited explanation of the processes through which SI operationalises CE principles, as SI and CE have largely evolved in parallel and existing conceptualisations remain predominantly descriptive ...

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

White-Box Tweakable Block Cipher and Hardware-Binding Scheme Under Tweak-Unique Mode

Information
White-box cryptography protects secret keys in untrusted execution environments but remains vulnerable to code lifting attacks. Hardware-binding offers a practical countermeasure by coupling cryptographic implementations with specific devices, yet a ...

Cryptanalysis of Full-Round BipBip

IACR Transactions on Symmetric Cryptology
BipBip is a low-latency tweakable block cipher proposed by Belkheyar et al. in 2023. It was designed for pointer encryption inside a new memory safety mechanism called Cryptographic Capability Computing (C3). BipBip encrypts blocks of 24 bits using a 40-

Recomposing Management Education Under Climate Crisis: Towards a Composting Heuristic for Epistemic Change

British Journal of Management, EarlyView.
Abstract Management learning and education (MLE) is increasingly critiqued for its reliance on anthropocentric and profit‐maximization paradigms, which fail to adequately address the escalating ecological and climate crises. In this article, we call for an epistemic shift in MLE by introducing the metaphor of composting as a lens for collective ...
