Dynamic Rounds Chaotic Block Cipher Based on Keyword Abstract Extraction [PDF]
Entropy, 2018 According to the keyword abstract extraction function in the Natural Language Processing and Information Retrieval Sharing Platform (NLPIR), the design method of a dynamic rounds chaotic block cipher is presented in this paper, which takes into account ...

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

Proposal of New Block Cipher Algorithm [PDF]
Engineering and Technology Journal, 2010 Speed and complexity are two important properties in the block cipher.The block length of the block cipher controls these two aspects. The speedlimitation enforces the designer to build block cipher system as hardwareprototype.

, 2011 We present a new block cipher LED. While dedicated to compact hardware implementation, and offering the smallest silicon footprint among comparable block ciphers, the cipher has been designed to simultaneously tackle three additional goals. First, we explore the role of an ultra-light (in fact non-existent) key schedule.

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

, 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.

Iterative Block Ciphers from Tweakable Block Ciphers with Long Tweaks
IACR Transactions on Symmetric Cryptology, 2020 We consider a problem of constructing a secure block cipher from a tweakable block cipher (TBC) with long tweaks. Given a TBC with n-bit blocks and Γn-bit tweaks for Γ ≥ 1, one of the constructions by Minematsu in DCC 2015 shows that a simple iteration ...
