A New Conditional Cube Attack on Reduced-Round Ascon-128a in a Nonce-misuse Setting

May 10, 2022

Presenters

Donghoon Chang - Strativia-NIST

Description

Ascon is one of the finalists of the National Institute of Standards and Technology (NIST) lightweight cryptography standardization process. The Ascon family is a permutation-based design that uses monkeyDuplex construction with extra key additions during initialization and finalization to prevent key-recovery and forgery attacks even after the internal state is recovered by an attacker during the encryption. The family includes three AEAD variants; Ascon-128 (primary), Ascon-128a, and Ascon-80pq. The Ascon family received a significant amount of third party analysis.
