Significantly Improved Multi-bit Differentials for Reduced Round Salsa and ChaCha

IACR Transactions on Symmetric Cryptology, 2017
ChaCha and Salsa are two software oriented stream ciphers that have attracted serious attention in academic as well as commercial domain. The most important cryptanalysis of reduced versions of these ciphers was presented by Aumasson et al.

A Quantum Differential Attack on ChaCha and Related Resources Estimation

IEEE Access
Existing classical cryptanalytic techniques against ChaCha primarily rely on differential cryptanalysis, leveraging probabilistic neutral bits (PNBs) introduced by Aumasson et al. Separately, Bathe et al.

Cryptanalysis for reduced round Salsa and ChaCha: revisited [PDF]

IET Information Security, 2019
Maitra et al . (WCC‐2015) proposed the characterisation of valid states by reversing the one round of Salsa20. When revisited, a mistake was found in the one bit change of eighth and ninth word while reversing the one round result to a valid initial state. It was mentioned in WCC‐2015 that it

Belgisch socialisme en kolonisering: dépendance chacha? [PDF]

Brood & Rozen, 2010
De houding van ‘links’ tegenover kolonisering is niet rechtlijnig. Bij Marx zelf was er reeds een ambivalentie tegenover de kolonisering: enerzijds vond hij dat de volkeren uit het Zuiden niet veel meer te verliezen hadden dan hun achterlijkheid, anderzijds klaagde hij de uitbuiting aan.

Impact of Passive Solar Drying and Storage on Secondary Plant Metabolites and Nitrate Contents of Abyssinian Mustard, Amaranth, and Pumpkin Leaves. [PDF]

J Food Sci
ABSTRACT The present study compared the effect of passive direct solar dryer (PDSD) and passive indirect solar dryer (PISD), each followed by a 30‐day storage period, on the secondary plant metabolite and nitrate contents of amaranth, Abyssinian mustard, and pumpkin leaves.

Impact of Health Education Interventions for Control of <i>Taenia solium</i> Cysticercosis/Taeniasis in Endemic Countries: A Systematic Review. [PDF]

Public Health Chall
This systematic review assessed health education interventions for controlling Taenia solium taeniasis/cysticercosis. Of 392 studies screened, 21 met the inclusion criteria. Findings showed that community‐based education improved knowledge, attitudes and practices, with short‐term behavioural changes and reduced prevalence, although long‐term impact ...

Hybrid lightweight cryptography with attribute-based encryption standard for secure and scalable IoT system

Connection Science, 2022
Internet of Things (IoT) devices require lower power consumption with higher security, which can be achieved by using lightweight cryptography (LWC) approaches. Attribute-based encryption (ABE) provides a fine-grained access control policy over encrypted

Rotational Cryptanalysis on ChaCha Stream Cipher

Symmetry, 2022
In this paper we consider the ChaCha20 stream cipher in the related-key scenario and we study how to obtain rotational-XOR pairs with nonzero probability after the application of the first quarter round. The ChaCha20 input can be viewed as a 4×4 matrix of 32-bit words, where the first row of the matrix is fixed to a constant value, the second two rows ...
