ePrint Report: Automatic Preimage Attack Framework on \ascon Using a Linearize-and-Guess Approach

Huina Li, Le He, Shiyao Chen, Jian Guo, Weidong Qiu

\ascon is the final winner of the lightweight cryptography standardization competition $(2018-2023)$.
In this paper, we focus on preimage attacks against round-reduced \ascon.
The preimage attack framework, utilizing the linear structure with the allocating model, was initially proposed by Guo \textit{et al.} at ASIACRYPT 2016 and subsequently improved by Li \textit{et al.} at EUROCRYPT 2019, demonstrating high effectiveness …
