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

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 ...

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.
