Optimally Secure Tweakable Block Ciphers with a Large Tweak from n-bit Block Ciphers
IACR Transactions on Symmetric Cryptology, 2023 We consider the design of a tweakable block cipher from a block cipher whose inputs and outputs are of size n bits. The main goal is to achieve 2n security with a large tweak (i.e., more than n bits). Previously, Mennink at FSE’15 and Wang et al.

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.

Matrix Power Function Based Block Cipher Operating in CBC Mode
Mathematics, 2022 In our previous study, we proposed a perfectly secure Shannon cipher based on the so-called matrix power function. There we also introduced a concept of single round symmetric encryption, i.e., we used the matrix power function together with some rather ...

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
