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

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.

COUNTER MODE DEVELOPMENT FOR BLOCK CIPHER OPERATIONS [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 There are two basic types of symmetric cipher: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer. Stream ciphers operate on streams of plaintext and ciphertext one bit or

Applied Sciences, 2022 With the advent of the Internet of Things (IoT) and cloud computing technologies, vast amounts of data are being created and communicated in IoT networks. Block ciphers are being used to protect these data from malicious attacks.

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 ...
