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.

The Security of Cipher Block Chaining [PDF]
, 2007 The Cipher Block Chaining - Message Authentication Code (CBC MAC) specifies that a, message x = x1 ... xm be authenticated among parties who share a secret key a by tagging x with a prefix of fa(m)(x) def = fa(fa(... fa(fa(x1)?x2)?...?xm-1)?xm), where f is some underlying block cipher (eg. f = DES). This method is a pervasively used international and U.

XHX - A Framework for Optimally Secure Tweakable Block Ciphers from Classical Block Ciphers and Universal Hashing [PDF]
, 2021 Tweakable block ciphers are important primitives for designing cryptographic schemes with high security. In the absence of a standardized tweakable block cipher, constructions built from classical block ciphers remain an interesting research topic in ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Fast implementations of ARX-based lightweight block ciphers (SPARX, CHAM) on 32-bit processor
International Journal of Distributed Sensor Networks, 2019 Recently, many lightweight block ciphers are proposed, such as PRESENT, SIMON, SPECK, Simeck, SPARX, GIFT, and CHAM. Most of these ciphers are designed with Addition–Rotation–Xor (ARX)-based structure for the resource-constrained environment because ARX ...

, 2006 . We introduce the new concept of elastic block ciphers, symmetrickey encryption algorithms that (1) for a variable-size input do not expand the plaintext (i.e., do not require plaintext padding) and (2) adjust their computational load proportionally to ...
