Linear Cryptanalysis on SPN cipher. Contribute to fazli96/CZ4010-Assignment development by creating an account on GitHub.

For instance, during an analysis of a lightweight block cipher, we observed that one of the linear characteristics had a bias of 0.1, indicating a lower correlation between plaintext and ciphertext.

Initially we take a very large corpus with all possible texts, We loop over each character encode with shift cipher of key=5 We take the original characters as Y array and Encrypted characters as X ...

It is an interesting work to find zero-correlation linear distinguishers of block ciphers with a nonlinear key schedule. More information: Yi Zhang et al, Zero-correlation linear attack on ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.
