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

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.

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.

On Elastic Block Ciphers and Their Differential and Linear Cryptanalyses [PDF]
, 2005 Motivated by applications such as databases with nonuniform field lengths, we introduce the concept of an elastic block cipher, a new approach to variable length block ciphers which incorporates fixed sized cipher components into a new network structure.

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 ...

Quantitative Evaluation of Chaotic CBC Mode of Operation [PDF]
, 2016 The cipher block chaining (CBC) block cipher mode of operation presents a very popular way of encrypting which is used in various applications. In previous research work, we have mathematically proven that, under some conditions, this mode of operation ...
