Comprehensive Neural Cryptanalysis on Block Ciphers Using Different Encryption Methods

open access: yesMathematics
In this paper, we perform neural cryptanalysis on five block ciphers: Data Encryption Standard (DES), Simplified DES (SDES), Advanced Encryption Standard (AES), Simplified AES (SAES), and SPECK.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Symmetric block ciphers with a block length of 32 bit [PDF]

open access: yes, 2018
Subject of the thesis at hand is the analysis of symmetric block ciphers with a block length of 32 bit. It is meant to give a comprising overview over the topic of 32 bit block ciphers. The topic is divided in the examination of three questions.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Towards distributing block ciphers computations

open access: yes, 2015
Providing data confidentiality for energyconstrained devices has proven to be a hard problem. Over the years many efficient implementations of well-known block ciphers, as well as a large number of new “lightweight” block ciphers, have been introduced ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

An efficient permutation approach for SbPN-based symmetric block ciphers

open access: yesCybersecurity, 2023
It is challenging to devise lightweight cryptographic primitives efficient in both hardware and software that can provide an optimum level of security to diverse Internet of Things applications running on low-end constrained devices.

Cryptanalysis of QTL Block Cipher

open access: yes, 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]

open access: yes, 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.
