Single Trace Side Channel Analysis on NTRU Implementation

Applied Sciences, 2018
As researches on the quantum computer have progressed immensely, interests in post-quantum cryptography have greatly increased. NTRU is one of the well-known algorithms due to its practical key sizes and fast performance along with the resistance against

S-Box on Subgroup of Galois Field

Cryptography, 2019
In substitution−permutation network as a cryptosystem, substitution boxes play the role of the only nonlinear part. It would be easy for adversaries to compromise the security of the system without them.

Decoding the Tensor Product of MLD Codes and Applications for Code Cryptosystems

Моделирование и анализ информационных систем, 2017
For the practical application of code cryptosystems such as McEliece, it is necessary that the code used in the cryptosystem should have a fast decoding algorithm.

How Fast can be Algebraic Attacks on Block Ciphers?

IACR Cryptol. ePrint Arch., 2006
In my talk I did overwiev the area of algebraic attacks on block ciphers, explain what fast algebraic attacks on block cipher are, and what results can already be achieved. This covers a vast amount of work (several papers, most of them not published) that I cannot include here in totality due to the lack of space.

Evaluating the Resistance of Stream Ciphers with Linear Feedback Against Fast Algebraic Attacks [PDF]

, 2006
In this paper we evaluate the resistance of stream ciphers with linear feedback against fast algebraic attacks. We summarize the current knowledge about fast algebraic attacks, develop new and more efficient algorithms to evaluate the resistance against fast algebraic attacks, study theoretical bounds on the attacks, and apply our methodology to the ...

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Beyond Percolation: Graphene‐Enabled Network Reinforcement Enhances Thermal Transport in Paraffin Phase‐Change Composites

Advanced Science, EarlyView.
Expanded‐graphite/graphene‐nanoplatelet hybrids deliver a near‐order‐of‐magnitude thermal‐conductivity enhancement in paraffin phase‐change materials. A microCT‐informed 3D modeling framework resolves the percolating EG backbone and captures sub‐voxel GNP enrichment, quantitatively linking microstructure to heat flow and revealing a graphene‐enabled ...

Monolith: Circuit-Friendly Hash Functions with New Nonlinear Layers for Fast and Constant-Time Implementations

IACR Transactions on Symmetric Cryptology
Hash functions are a crucial component in incrementally verifiable computation (IVC) protocols and applications. Among those, recursive SNARKs and folding schemes require hash functions to be both fast in native CPU computations and compact in algebraic

An exciting Approach to Theoretical Spectroscopy

Advanced Science, EarlyView.
ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

Advanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...
