Recover plaintext attack to block ciphers [PDF]
arXiv, 2008 we will present an estimation for the upper-bound of the amount of 16-bytes plaintexts for English texts, which indicates that the block ciphers with block length no more than 16-bytes will be subject to recover plaintext attacks in the occasions of plaintext -known or plaintext-chosen attacks.

Key classification attack on block ciphers [PDF]
arXiv, 2013 In this paper, security analysis of block ciphers with key length greater than block length is proposed. When key length is significantly greater than block length and the statistical distribution of cipher system is like a uniform distribution, there are more than one key which map fixed input to fixed output.

New Methodology of Block Cipher Analysis using Chaos Game [PDF]
ITB Journal of Information and Communication Technology, 2011 Block cipher analysis covers randomness analysis and cryptanalysis. This paper proposes a new method potentially used for randomness analysis and cryptanalysis. The method uses true random sequence concept as a reference for measuring randomness level of

On some block ciphers and imprimitive groups [PDF]
Applicable Algebra in Engineering, Communication and Computing, 2009 The group generated by the round functions of a block ciphers is a widely investigated problem. We identify a large class of block ciphers for which such group is easily guaranteed to be primitive. Our class includes the AES and the SERPENT.

Systematization of a 256-bit lightweight block cipher Marvin [PDF]
arXiv, 2018 In a world heavily loaded by information, there is a great need for keeping specific information secure from adversaries. The rapid growth in the research field of lightweight cryptography can be seen from the list of the number of lightweight stream as well as block ciphers that has been proposed in the recent years.

New mode of operation inspired by the braid of long hair [PDF]
Revista Română de Informatică și Automatică, 2023 In cryptography, a mode of operation is the way of processing plaintext and encrypted text blocks within a block cipher algorithm, or it is the presentation of a method of chaining blocks in a block cipher.

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.
