The linear layer is a core component in any substitution-permutation network block cipher.
Its design significantly influences both the security and the efficiency of the resulting block …

Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the
action of a secret key, and the process of encryption is reversed by decryption which uses …

In this paper, we propose a 128-bit block cipher ARIA which is an involution substitution and
permutation encryption network (SPN). We use the same S-boxes as Rijndael to eliminate …

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 …

We study the synthesis of small functions used as building blocks in lightweight
cryptographic designs in terms of hardware implementations. This phase most notably …

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 …

While differential behavior of modern ciphers in a single secret key scenario is relatively well
understood, and simple techniques for computation of security lower bounds are readily …
