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

Short Non-Malleable Codes from Related-Key Secure Block Ciphers, Revisited
IACR Transactions on Symmetric Cryptology, 2022 We construct non-malleable codes in the split-state model with codeword length m + 3λ or m + 5λ, where m is the message size and λ is the security parameter, depending on how conservative one is. Our scheme is very simple and involves a single call to a

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.

Elastic Block Ciphers: Method, Security and Instantiations [PDF]
, 2009 We introduce the concept of an elastic block cipher which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size ...
