The related-key model is now considered an important scenario for block cipher security and many schemes were broken in this model, even AES-192 and AES-256. Recently were introduced efficient computer-based search tools that can produce the best pos

This paper proposes improved algebraic attacks that are effective for lightweight block ciphers. Concretely, we propose a new framework that leverages on algebraic preprocessing as well as modern SAT solvers to perform algebraic cryptanalysis on bloc

Algebraic differential fault attack (ADFA) is an attack in which an attacker combines a differential fault attack and an algebraic technique to break a targeted cipher. In this paper, we present three attacks using three different algebraic technique

Many block ciphers and hash functions require the diffusion property of Maximum Distance Separable (MDS) matrices. Serial matrices with the MDS property obtain a trade-off between area requirement and clock cycle performance to meet the needs of ligh

In this paper, we study GF-NLFSR, a Generalized Unbalanced Feistel Network (GUFN) which can be considered as an extension of the outer function FO of the KASUMI block cipher. We show that the differential and linear probabilities of any n?+?1 rounds

In this paper, we present the time-memory-data (TMD) trade-off attack on stream ciphers filter function generators and filter cominers based on Maiorana-McFarland functions. This can be considered as a generalization of the time-memory-data trade-off

We construct two classes of balanced S-boxes with high nonlinearity 2 n-1−2(n-1)/2 for n odd. From known results, it can be deduced that for any S-box which has nonlinearity 2 n-1−2(n-1)/2, the unrestricted nonlinearity is lower bounded by 2 n-1

We investigate the security of $n$-bit to $m$-bit vectorial Boolean functions in stream ciphers. Such stream ciphers have higher throughput than those using single-bit output Boolean functions. However, as shown by Zhang and Chan at Crypto 2000, line

In the past twenty years, there were only a few constructions for Boolean functions with nonlinearity exceeding the quadratic bound 2n-1 - 2(n-1)/2 when n is odd (we shall call them Boolean functions with very high nonlinearity). The first basic cons
