Construction of block ciphers: new possibilities [PDF]
, 2003 Artykuł pokazuje nowe konstrukcje kodów blokowych.The paper is an explication of how to construct block ciphers in a completely new way. The paper can be divided into three parts. In the first part the foundations of the construction of block ciphers and

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Algebraic Side Channel Attack on Trivium and Grain Ciphers
IEEE Access, 2017 Solving a system of multivariate quadratic equations obtained through algebraic cryptanalysis is a nondeterministic polynomial time-complete problem. Owing to the trend of stream ciphers based on nonlinear update, the success of algebraic attacks has ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Elastic Block Ciphers: The Feistel Cipher Case [PDF]
, 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.

LBlock: A Lightweight Block Cipher [PDF]
, 2011 In this paper, we propose a new lightweight block cipher called LBlock. Similar to many other lightweight block ciphers, the block size of LBlock is 64-bit and the key size is 80-bit. Our security evaluation shows that LBlock can achieve enough security margin against known attacks, such as differential cryptanalysis, linear cryptanalysis, impossible ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Block Ciphers and Systems of Quadratic Equations [PDF]
, 2003 In this paper we compare systems of multivariate polynomials, which completely define the block ciphers Khazad, Misty1, Kasumi, Camellia, Rijndael and Serpent in the view of a potential danger of an algebraic re-linearization ...

Tweakable Block Ciphers Secure Beyond the Birthday Bound in the Ideal Cipher Model [PDF]
, 2018 We propose a new construction of tweakable block ciphers from standard block ciphers. Our construction, dubbed XHX2, is the cascade of two independent XHX block ciphers, so it makes two call to the underlying block cipher using tweak-dependent keys.
