Exploring Differential-Based Distinguishers and Forgeries for ASCON
IACR Transactions on Symmetric Cryptology, 2021 Automated methods have become crucial components when searching for distinguishers against symmetric-key cryptographic primitives. While MILP and SAT solvers are among the most popular tools to model ciphers and perform cryptanalysis, other methods with ...

Conditional Cube Attack on Round-Reduced ASCON
IACR Transactions on Symmetric Cryptology, 2017 This paper evaluates the secure level of authenticated encryption Ascon against cube-like method. Ascon submitted by Dobraunig et al. is one of 16 survivors of the 3rd round CAESAR competition. The cube-like method is first used by Dinur et al.

New Differential-Based Distinguishers for Ascon via Constraint Programming
IET Information SecurityAs the winner of the NIST lightweight cryptography project, Ascon has undergone extensive self-evaluation and third-party cryptanalysis. In this paper, we use constraint programming (CP) as a tool to analyze the Ascon permutation and propose several ...

Committing Security of Ascon: Cryptanalysis on Primitive and Proof on Mode
IACR Transactions on Symmetric Cryptology, 2023 Context-committing security of authenticated encryption (AE) that prevents ciphertexts from being decrypted with distinct decryption contexts, (K,N,A) comprising a key K, a nonce N, and associate data A is an active research field motivated by several ...

Fetal central nervous system anomalies according to RT-PCR and trimester of maternal infection with Zika virus: A prospective cohort study. [PDF]
Acta Obstet Gynecol Scand, 2022 Abstract Introduction In October 2015, an epidemic of Zika began in Colombia’s geographic areas with a high population of mosquitoes of the genus Aedes. We aimed to describe the fetal brain ultrasound findings in pregnant women with active symptoms or a history of symptoms suggestive of Zika virus (ZIKV) infection.
