, 1997 In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against differential and linear cryptanalysis. However, after the initial design a dedicated attack was mounted that forced us to augment the number of rounds.

CRITERIA FOR MARKOV BLOCK CIPHERS
Prikladnaya diskretnaya matematika, 2018 Summary: We study probabilistic models of block ciphers with random independent identically distributed round keys. We call they Markov ciphers if sequence of round differentials is a simple homogeneous Markov chain. Criteria and sufficient condition for this property are adjusted and generalized.

, 2002 In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256- bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers is S-box or logical operation, which has been well studied about

Cryptanalysis of QTL Block Cipher
, 2017 QTL is an ultra-lightweight block cipher designed for extremely constrained devices. The cipher has two versions, QLT-64 and QTL-128 supporting key lengths of 64 and 128 bits, respectively. In this paper, we present the first third party cryptanalysis of QTL. We first introduce related key distinguishers for full versions of the cipher.

Elastic Block Ciphers: The Feistel Cipher Case
, 2004 We discuss the elastic versions of block ciphers whose round function processes subsets of bits from the data block differently, such as occurs in a Feistel network and in MISTY1. We focus on how specific bits are selected to be swapped after each round when forming the elastic version, using an elastic version of MISTY1 and differential cryptanalysis ...

The "one-group-one-cipher" cryptograph of block-cipher based on chaotic
Tongxin xuebao, 2009 The"one-group-one-cipher"algorithm used the sequence from chaotic mapping as sub-key for block cipher was presented to solve the problem of weak keys existing in currently combined cipher algorithms.The randomness of abstracted key sequence was validated
