Cryptanalysis of Round-Reduced KECCAK using Non-Linear Structures
KECCAK SHA-3 Hash function
2019/8/2
In this paper, we present new preimage attacks on KECCAK-384 and KECCAK-512 for 2, 3 and 4 rounds. The attacks are based on non-linear structures (structures that contain quadratic terms). These struc...
On the Existence of Non-Linear Invariants and Algebraic Polynomial Constructive Approach to Backdoors in Block Ciphers
block ciphers Boolean functions Algebraic Normal Form
2018/11/19
In this paper we study cryptanalysis with non-linear polynomials cf. Eurocrypt’95 (adapted to Feistel ciphers at Crypto 2004). Previously researchers had serious difficulties in making such attacks wo...
Linear Equivalence of Block Ciphers with Partial Non-Linear Layers: Application to LowMC
Block cipher LowMC Picnic signature algorithm linear equivalence
2018/8/28
LowMC is a block cipher family that is optimized for practical instantiations of multi-party computation, fully homomorphic encryption, and zero-knowledge proofs. It was designed in 2015 by Albrecht e...
COMPARISON OF THE LINEAR AND THE NON-LINEAR BLOCK ADJUSTMENT ON SATELLITE IMAGES RESEARCH
Linear Least square method Non-Linear Least square method error equation Block adjustment Rational Function Model High-resolution Satellite images
2018/5/14
The Rational Function Model （RFM） is a non-linear model. Usually, the RFM-based satellite image block adjustment uses the Taylor series to expand error equations, and then solves the linear model. The...
Practical Cryptanalysis of a Public-key Encryption Scheme Based on Non-linear Indeterminate Equations at SAC 2017
Public-Key Encryption Indeterminate Equations Cryptosystem Post-quantum cryptography
2017/12/25
Abstract. We investigate the security of a public-key encryption scheme, the Indeterminate Equation Cryptosystem (IEC), introduced by Akiyama, Goto, Okumura, Takagi, Nuida, and Hanaoka at SAC 2017 as ...
A Public-key Encryption Scheme Based on Non-linear Indeterminate Equations (Giophantus)
Public-key Cryptosystem Post-Quantum Cryptosystem Indeterminate Equation
2017/12/25
In this paper, we propose a post-quantum public-key encryption scheme whose security depends on a problem arising from a multivariate non-linear indeterminate equation. The security of lattice cryptos...
Image Classification using non-linear Support Vector Machines on Encrypted Data

2017/9/13
In image processing, algorithms for object classification are typically based around machine learning. From the algorithm developer's perspective, these can involve a considerable amount of effort and...
Determining the Nonexistent Terms of Non-linear Multivariate Polynomials: How to Break Grain-128 More Efficiently
Stream ciphers Grain-128 Polynomial reduction
2017/5/15
In this paper, we propose a reduction technique that can be used to determine the density of IV terms of a complex multivariable boolean polynomial. Using this technique, we revisit the dynamic cube a...
Reducing the Number of Non-linear Multiplications in Masking Schemes
side-channel countermeasure masking probing security
2016/12/10
In recent years, methods to securely mask S-boxes against side-channel attacks by representing them as polynomials over finite binary fields have become quite efficient. A good cost model for this is ...
