D.STVL.7 - Algebraic cryptanalysis of symmetric primitives [PDF]

, 2008
The recent development of algebraic attacks can be considered an important breakthrough in the analysis of symmetric primitives; these are powerful techniques that apply to both block and stream ciphers (and potentially hash functions).

Improvement and evaluation for algebraic fault attacks on PRESENT

Tongxin xuebao, 2016
An enhanced algebraic fault analysis on PRESENT was proposed.Algebraic cryptanalysis was introduced to build the algebraic equations for both the target cipher and faults.The equation set of PRESENT was built reversely in order to accelerate the solving ...

Key Generation Using Generalized Pell’s Equation in Public Key Cryptography Based on the Prime Fake Modulus Principle to Image Encryption and Its Security Analysis

Cybernetics and Information Technologies, 2020
RSA is one among the most popular public key cryptographic algorithm for security systems. It is explored in the results that RSA is prone to factorization problem, since it is sharing common modulus and public key exponent.

The Cryptanalysis Of The Enigma Cipher. The Plugboard And The Cryptologic Bomb.

Computer Science, 2014
We study the problem of decoding secret messages encrypted by the German Army with the M3 Enigma machine after September 15, 1938. We focused our attention on the algorithmization and programming of this problem. A completion and optimization of Zygalski’

A new S-box pattern generation based on chaotic enhanced logistic map: case of 5-bit S-box

Cybersecurity
Cryptography plays consistently an essential role in securing any sort of communications or data broadcast over the network. Since the security of any designed block cipher algorithm is related to its Substitution box (S-box), several efforts have been ...

Yet Another Algebraic Cryptanalysis of Small Scale Variants of AES [PDF]

, 2022
This work presents new advances in algebraic cryptanalysis of small scale derivatives of AES. We model the cipher as a system of polynomial equations over GF(2), which involves only the variables of the initial key, and we subsequently attempt to solve ...

Higher-order differences based research on comparison between type-1 generalized Feistel-SP network and Feistel-SPSP network

Tongxin xuebao, 2014
The powers against the higher-order differential cryptanalysis of the single-SP(substitution-permutation) model and the double-SP model are studied in the type-1 Feistel network by analyzing the growths of algebraic degrees.

Parameters of Algebraic Representation vs. Efficiency of Algebraic Cryptanalysis [PDF]

The aim of an algebraic attack is to find the secret key by solving a collection of relations that describe the internal structure of a cipher for observations of plaintext/cipher-text pairs.
