XHX - A Framework for Optimally Secure Tweakable Block Ciphers from Classical Block Ciphers and Universal Hashing [PDF]
, 2021 Tweakable block ciphers are important primitives for designing cryptographic schemes with high security. In the absence of a standardized tweakable block cipher, constructions built from classical block ciphers remain an interesting research topic in ...

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments
Chemie Ingenieur Technik, EarlyView.This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Cryptanalysis of IAR-CTR and IAR-CFB and a fixing method
CybersecurityWe present practical attacks on IAR-CTR and IAR-CFB, AE modes proposed by Hwang and Gope to offer both privacy and authenticity in a single pass. Then we use the idea of iCOFB, which is originally defined with a tweakable random function, to fix the IAR ...

THF: Designing Low-Latency Tweakable Block Ciphers
IACR Transactions on Symmetric CryptologyWe introduce the Three-Hash Framework (THF), a new instantiation of the LRW+ paradigm that employs three hash functions to process tweak inputs. We prove that THF achieves beyond-birthday-bound security under standard assumptions. By extending the general practical cryptanalysis framework to the multiple-tweak setting, we further demonstrate that THF ...

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays
Cytoskeleton, EarlyView.ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

Environmental Policy and Governance, EarlyView.ABSTRACT Thailand has announced ambitious plans to reduce greenhouse gas emissions, including a programme that allows private companies to earn carbon credits from protecting and restoring mangroves. In 2023, the Department of Marine and Coastal Resources (DMCR) began enrolling local communities and private firms in this scheme.

Environmental Policy and Governance, EarlyView.ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Provable Security of (Tweakable) Block Ciphers Based on Substitution-Permutation Networks [PDF]
, 2018 Substitution-Permutation Networks (SPNs) refer to a family of constructions which build a wn-bit block cipher from n-bit public permutations (often called S-boxes), which alternate keyless and “local” substitution steps utilizing such S-boxes, with keyed and “global” permutation steps which are non-cryptographic.

Food Biomacromolecules, EarlyView.Agar xerogel was used to immobilize cellulase. Properties of partially purified cellulase from Aspergillus foetidus and commercial cellulase were compared after immobilization. Abstract This research study is a comparative study of the characteristics of partially purified cellulase produced from Aspergillus foetidus through solid‐state fermentation ...
