The Security of Elastic Block Ciphers Against Key-Recovery Attacks
We analyze the security of elastic block ciphers against key-recovery attacks. An elastic version of a fixed-length block cipher is a variable-length block cipher that supports an...

Algebraic Cryptanalysis of the Data Encryption Standard
In spite of growing importance of AES, the Data Encryption Standard is by no means obsolete. DES has never been broken from the practical point of view. The triple DES is believed ...

Elastic block ciphers: the basic design
We introduce the concept of an elastic block cipher, which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while ...

Unknown Plaintext Template Attacks
In this paper we present a variation of the template attack classification process that can be applied to block ciphers when the plaintext and ciphertext used are unknown. In a na...

Algebraic Techniques in Differential Cryptanalysis
In this paper we propose a new cryptanalytic method against block ciphers, which combines both algebraic and statistical techniques. More specifically, we show how to use algebraic...

KATAN and KTANTAN - A Family of Small and Efficient Hardware-Oriented Block Ciphers
Abstract. In this paper we propose a new family of very efficient hardware oriented block ciphers. The family contains six block ciphers divided into two flavors. All block ciphers...
