This paper describes a randomness test which can be used to measure the cryptographic
strength of a block cipher or its underlying cryptographic primitive (s). Cryptographic strength …

In this paper, we give a general framework for the analysis of block ciphers using the
statistical technique of likelihood estimation. We show how various recent successful …

One of the most basic properties expected from block ciphers and hash functions is passing
statistical randomness testing, as they are expected to behave like random mappings …

Most last-round attacks on iterated block ciphers provide some design criteria for the round
function. Here, we focus on the links between the underlying properties. Most notably, we …

Confusion and diffusion suggested by Claude Shannon are two techniques that symmetric
key ciphers should satisfy to prevent cryptanalysis. Diffusion dissipates the statistical …

Since the development of cryptology in the industrial and academic worlds in the seventies,
public knowledge and expertise have grown in a tremendous way, notably because of the …

Nyberg and Knudsen proved that the maximum average of differential probability (ADP max)
and the maximum average of linear probability (ALP max) of Feistel cipher with over 4 …

This report summarizes readings in the area of the cryptanalysis of block ciphers.
Historically, the academic field started in 1981 with the first CRYPTO conference and …

In this paper we give a short overview of the state of the art of secret key block ciphers. We
focus on the main application of block ciphers, namely for encryption. The most important …
