Randomness of encryption keys generated by super H-antimagic total labeling

open access: yesIndonesian Journal of Combinatorics, 2020
SuperH-antimagic total labeling (SHATL) can be utilized to generate encryption keys. The keys are then used to establish the improved block and stream ciphers.

Two Practical and Provably Secure Block Ciphers: BEAR and LION

open access: yes, 1996
In this paper we suggest two new provably secure block ciphers, called BEAR and LION. They both have large block sizes, and are based on the Luby-Rackoff construction.

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Block ciphers identification scheme based on the distribution character of randomness test values of ciphertext

open access: yesTongxin xuebao, 2015
By researching deficiency of current encryption algorithms identification schemes,a block ciphers identification scheme is proposed based on the distribution character of randomness test values for ciphertext.Firstly,the numbers of randomness test values

Elastic block ciphers

open access: yesProceedings of the 2nd ACM symposium on Information, computer and communications security, 2007
We introduce the concept of an elastic block cipher, which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size. We define a method for converting any existing block cipher into an elastic block cipher and mention

HI-2 Comparisons of Hardware Implementations

open access: yes, 2008
— FPGA implementations of different Stream Ciphers and Block Ciphers are compared in this paper in terms of Speed, Area and Throughput. Different papers that report results of FPGA implementations of various Stream and Block Ciphers have been analyzed to

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.

Analysis of linear relationships in block ciphers

open access: yes, 2010
This thesis is devoted to the study of linear relationships in symmetric block ciphers. A block cipher is designed so that the ciphertext is produced as a nonlinear function of the plaintext and secret master key. However, linear relationships within the

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Algebraic Side Channel Attack on Trivium and Grain Ciphers

open access: yesIEEE 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 ...
