Lightweight but Not Easy: Side-channel Analysis of the Ascon Authenticated Cipher on a 32-bit Microcontroller

ePrint Report: Lightweight but Not Easy: Side-channel Analysis of the Ascon Authenticated Cipher on a 32-bit Microcontroller

Léo Weissbart, Stjepan Picek

Ascon is a recently standardized suite of symmetric cryptography for authenticated encryption and hashing algorithms designed to be lightweight.
The Ascon scheme has been studied since it was introduced in 2015 for the CAESAR competition, and many efforts have been made to transform this hardware-oriented scheme to work with any embedded device architecture.
Ascon is designed with side-channel resistance …
