Collision Attack on 4-branch, Type-2 GFN based Hash Functions using Sliced Biclique Cryptanalysis Technique [PDF]

, 2015
In this work, we apply the sliced biclique cryptanalysis technique to show 8-round collision attack on a hash function H based on 4-branch, Type-2 Generalized Feistel Network (Type-2 GFN).

Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

Advanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

Improved integral attack——random linear distinguish and key recovery attack

Tongxin xuebao, 2023
Based on the integral attack and collision attack of four rounds of AES, a random linear distinguish attack against four rounds of SP block ciphers was proposed, which took advantage of the non-uniformity of linear biases’ distribution between some ...

Ultrathin High‐Efficiency Zener Diode Fabricated Using Organized ZnS Nanoparticles in Surface‐Grafted Poly(methacrylic acid) Matrix

Advanced Electronic Materials, EarlyView.
This work presents a unique approach for fabricating homogeneously dispersed ZnS nanoparticles within an ultra‐thin (<40 nm) polymer matrix. The uniformity of dispersion is ensured through post‐polymerization substitution of Zn2⁺‐terminated side groups in surface‐grafted PMAA brushes. Due to the homogeneous distribution of semi‐conducting nanoparticles,

Comprehensive Analysis and Implementation of Isogeny-Based Hash Functions

IEEE Access
This paper analyzes the security and performance of the isogeny-based hash functions. The isogeny-based hash function was first proposed by Charles, Goren, and Lauter, and is referred to as the CGL hash function.

Collision Attack on GRINDAHL [PDF]

, 2016
Hash functions have been among the most scrutinized cryptographic primitives in the previous decade, mainly due to the cryptanalysis breakthroughs on MD-SHA family and the NIST SHA3 competition that followed.

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review

Advanced Energy and Sustainability Research, EarlyView.
The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.
