In this paper, we present a detailed tutorial on linear cryptanalysis and differential
cryptanalysis, the two most significant attacks applicable to symmetric-key block ciphers. The …

The area of practical computational integrity proof systems, like SNARKs, STARKs,
Bulletproofs, is seeing a very dynamic development with several constructions having …

Twofish is a 128-bit block cipher that accepts a variable-length key up to 256 bits. The cipher
is a 16-round Feistel network with a bijective F function made up of four key-dependent 8-by …

A matrix is MDS or super-regular if and only if every square submatrices of it are
nonsingular. MDS matrices provide perfect diffusion in block ciphers and hash functions. In …

It is a general belief among the designers of block-ciphers that even a relatively weak cipher
may become very strong if its number of rounds is made very large. In this paper we …

Khazad is a 64-bit (legacy-level) block cipher that accepts a 128-bit key. The cipher is a
uniform substitution-permutation network whose inverse only differs from the forward …

The security and performance of many integrity proof systems like SNARKs, STARKs and
Bulletproofs highly depend on the underlying hash function. For this reason several new …

In this article, we provide new methods to look for lightweight MDS matrices, and in
particular involutory ones. By proving many new properties and equivalence classes for …

Due to their remarkable application in many branches of applied mathematics such as
combinatorics, coding theory, and cryptography, Vandermonde matrices have received a …
