Ciphers that do not use S-boxes have been discussed for the demand on lightweight
cryptosystems, and their round functions consist of and, rotation, and xor. Especially, the …

Resource-efficient cryptographic primitives are essential for realizing both security and
efficiency in embedded systems like RFID tags and sensor nodes. Among those primitives …

We propose a new block cipher, DEAL, based on the DES (DEA). DEAL has a block size of
128 bits and allows for three key sizes of 128, 192, and 256 bits respectively. Our proposal …

We propose secret-key cryptosystems MISTY1 and MISTY2, which are block ciphers with a
128-bit key, a 64-bit block and a variable number of rounds. MISTY is a generic name for …

In this paper we consider some cryptographic implications of integrated circuit (IC) printing.
While still in its infancy, IC-printing allows the production and personalisation of circuits at …

MISTY1 is a block cipher designed by Matsui in 1997. It was well evaluated and
standardized by projects, such as CRYPTREC, ISO/IEC, and NESSIE. In this paper, we …

A Classical Introduction to Cryptography: Applications for Communications Security
introduces fundamentals of information and communication security by providing …

A simple network of small s-boxes can be proven secure against differential and linear
cryptanalysis. Upperbounds of the differential probabilities and the linear correlations are …

Several generalizations of linear cryptanalysis have been proposed in the past, as well as
very similar attacks in a statistical point of view. In this paper, we define a rigorous general …

In a recent paper we developed a new cryptanalytic technique based on impossible
differentials, and used it to attack the Skipjack encryption algorithm reduced from 32 to 31 …
