Cellular and Systemic Toxicity Induced by Sunscreen and Paraben Mixtures and the Implications for Root Development in Cultivated Plants

Journal of Toxicology, Volume 2026, Issue 1, 2026.
Sunscreens and parabens contaminate agricultural areas worldwide; however, the effects of these micropollutants in mixture on cultivated plants have not yet been reported. This study evaluated the cellular and systemic toxicity induced by octocrylene (OC), methylparaben (MeP), and butylparaben (BuP), individually at concentrations of 10, 50, 100, and ...

A novel distinguishing attack on Rocca

IET Communications, Volume 19, Issue 1, January/December 2025.
The study explores a novel attack originating from key commitment attacks that leverages the independence between ciphertext sequences, developing a distinguishing attack on Rocca. By utilizing a guess‐and‐determine approach, the attack reveals a vulnerability in Rocca, allowing the identification of another plaintext with comparable ciphertext ...

Weak Keys in the Rekeying Paradigm: Application to COMET and mixFeed

IACR Transactions on Symmetric Cryptology, 2020
In this paper, we study a group of AEAD schemes that use rekeying as a technique to increase efficiency by reducing the state size of the algorithm. We provide a unified model to study the behavior of the keys used in these schemes, called Rekey-and ...
