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,

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.

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

, 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

IEEE Access, 2021 Machine learning has recently started to gain the attention of cryptographic researchers, notably in block cipher cryptanalysis. Most of these machine learning-based approaches are black box attacks that are cipher-specific.

, 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.

, 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.
