Impossible differential cryptanalysis of lightweight tweakable block cipher CRAFT

open access: yesCybersecurity
Abstract The cipher is a lightweight tweakable block cipher introduced at FSE 2019. Its design aims to incorporate countermeasures against Differential Fault Attacks at the algorithmic level. The cipher employs a lightweight and involutory S-box along with a simple linear layer, enabling efficient encryption and decryption operations.

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...

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

open access: yesSustainable 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 ...

Cryptanalysis of Reduced round SKINNY Block Cipher

open access: yesIACR Transactions on Symmetric Cryptology, 2018
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different ...

Beyond-Birthday-Bound Security Based on Tweakable Block Cipher [PDF]

open access: yes, 2009
This paper studies how to build a 2n-bit block cipher which is hard to distinguish from a truly random permutation against attacks with q ≈ 2 n/2 queries, i.e., birthday attacks. Unlike previous approaches using pseudorandom functions, we present a simple and efficient proposal using a tweakable block cipher as an internal module.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

open access: yesSmall, 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.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Replication data for: The MALICIOUS Framework: Embedding Backdoors into Tweakable Block Ciphers

open access: yes, 2020
Inserting backdoors in encryption algorithms has long seemed like a very interesting, yet difficult problem. Most attempts have been unsuccessful for symmetric-key primitives so far and it remains an open problem how to build such ciphers.

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

open access: yesJournal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...
