Designing pair of nonlinear components of a block cipher over quaternion integers
AIMS Mathematics, 2023 In the field of cryptography, block ciphers are widely used to provide confidentiality and integrity of data. One of the key components of a block cipher is its nonlinear substitution function.

Block cipher four implementation on field programmable gate array
Communications in Science and Technology, 2020 Block ciphers are used to protect data in information systems from being leaked to unauthorized people. One of many block cipher algorithms developed by Indonesian researchers is the BCF (Block Cipher-Four) - a block cipher with 128-bit input/output that

Counter Mode Development for Block Cipher Operations [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 There are two basic types of symmetric algorithms: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer.

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,

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.

New Constructions of MACs from (Tweakable) Block Ciphers
IACR Transactions on Symmetric Cryptology, 2017 We propose new constructions of Message Authentication Codes (MACs) from tweakable or conventional block ciphers. Our new schemes are either stateless and deterministic, nonce-based, or randomized, and provably secure either in the standard model for ...

A General Analysis of the Security of Elastic Block Ciphers [PDF]
, 2005 We analyze the security of elastic block ciphers in general to show that an attack on an elastic version of block cipher implies a polynomial time related attack on the fixed-length version of the block cipher.
