Automated cryptanalysis of substitution permutation network cipher
This repo is a collection of proof-of-concepts, examples, essays and experiments in cryptography, cryptanalysis, steganography and covert channels that I originally wrote in 2015.
This is a library that tries to break SPN ciphers in an fully automatic manner.
my solutions for the HW in the symmetric cipher breaking course, all the HW are exercises from the https://cryptanex.hideinplainsight.io/ website
Учебно-исследовательский блочный шифр: блок 96 бит, ключ 256 бит, сеть Фейстеля, ARX. Реализации на Python и C, 8 тестовых наборов, 9 скриптов криптоанализа. Независимо не проверялся — не для реальных данных.
CRYPTO - Linear Cryptanalysis of Reduced-Round Speck with a Heuristic Approach: Automatic Search for Linear Trails
[French] Projet de cryptanalyse [English] Linear cryptanalysis
Browser-based demo of linear cryptanalysis — Matsui's 1993 attack that broke DES from known plaintext alone. Linear approximation table, the piling-up lemma compounding biases across rounds, and a live Algorithm 2 key recovery against a toy SPN.
