IACR Cryptol. ePrint Arch., 2004 We introduce the new concept of elastic block ciphers, symmetric-key encryption algorithms that (1) for a variable-size input do not expand the plaintext (i.e., do not require plaintext padding) and (2) adjust their computational load proportionally to ...

Journal of Cryptology, 2002 . We propose a new cryptographic primitive, the “tweakable block cipher. ” Such a cipher has not only the usual inputs—message and cryptographic key—but also a third input, the “tweak.

Cryptanalysis of Selected ARX-Based Block Ciphers
Vietnam Journal of Computer ScienceThe security of digital communication and information systems is mostly dependent on block ciphers. ARX-based ciphers are widely used due to their simplicity and efficiency.

XSL Block Ciphers’ Key-schedules with Resistance to Differential Cryptanalysis
Безопасность информационных технологий, 2014 The paper discusses the resistance of XSL block ciphers to differential cryptanalysis. AES-like block ciphers with alternative key-schedules (increased performance and density) are given as an example.

Probability distributions of correlation and differentials in block ciphers [PDF]
Journal of Mathematical Cryptology, 2007 We study the probability distributions of difference propagation probabilities and input-output correlations for functions and block ciphers of given dimensions, for several of them for the first time.

Probabilistic Block Cipher [PDF]
Annals of Computer Science and Information Systems, 2018 This paper is devoted to the description of a new block cipher that will be applicable in the post-quantum era and will not need a lot of resources. The main advantages: probabilistic encryption, the cipher block chaining mode, the ability to transfer to distributed systems. All this combined with the use of PRNG, working on the Cremona transformations,

, 2002 In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256- bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers is S-box or logical operation, which has been well studied about

, 1997 In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against differential and linear cryptanalysis. However, after the initial design a dedicated attack was mounted that forced us to augment the number of rounds.

Automated design of a lightweight block cipher with Genetic Programming [PDF]
, 2008 In this paper, we present a general framework for the automated design of cryptographic block ciphers by using Genetic Programming. We evolve highly nonlinear and extremely efficient functions that can be used as core components of any cryptographic ...
