TL;DR: A new method is introduced for cryptanalysis of DES cipher, which is essentially a known-plaintext attack, that is applicable to an only-ciphertext attack in certain situations.
Abstract: We introduce a new method for cryptanalysis of DES cipher, which is essentially a known-plaintext attack. As a result, it is possible to break 8-round DES cipher with 221 known-plaintexts and 16-round DES cipher with 247 known-plaintexts, respectively. Moreover, this method is applicable to an only-ciphertext attack in certain situations. For example, if plaintexts consist of natural English sentences represented by ASCII codes, 8-round DES cipher is breakable with 229 ciphertexts only.

TL;DR: In this paper, efficiently computable and easily implementable expressions for the exact differential and linear behaviour of Simon-like round functions are derived.
Abstract: In this paper we analyse the general class of functions underlying the Simon block cipher In particular, we derive efficiently computable and easily implementable expressions for the exact differential and linear behaviour of Simon-like round functions

TL;DR: This work exploits the ideas of Bringer et al. by further perturbing the representation of a cipher towards a white box implemen- tation, and applies it to a variant of the block cipher AES.
Abstract: At CMS 2006 Bringer et al. show how to conceal the alge- braic structure of a \traceable block cipher" by adding perturbations to its description. We here exploit and strengthen their ideas by further perturbing the representation of a cipher towards a white box implemen- tation. Our technique is quite general, and we apply it { as a challenging example in the domain of white box cryptography { to a variant of the block cipher AES.

TL;DR: Evidence is given that these properties can be exploited in the first 2 rounds of IDEA but that they are of no assistance in the cryptanalysis of the full IDEA block cipher containing 8 rounds.
Abstract: IDEA is an iterated block cipher proposed by Lai and Massey and is based on the design concept of "mixing operations from different algebraic groups". New arithmetic properties of the basic operations used in the round function are found and investigated with respect to the security of this block cipher. Evidence is given that these properties can be exploited in the cryptanalysis of the first 2 rounds of IDEA but that they are of no assistance in the cryptanalysis of the full IDEA block cipher containing 8 rounds.

TL;DR: The Tiny Encryption Algorithm is described, its simplicity of design and ease of use, its cryptographic strength, and the wide range of implementations and applications of the cipher.
Abstract: The Tiny Encryption Algorithm (TEA) has been around for just over ten years. It is probably the most "minimal"-and hence fastest-block cipher ever devised and yet appears resistant to most attacks. In this article, we describe the algorithm, its simplicity of design and ease of use, its cryptographic strength, and the wide range of implementations and applications of the cipher.
