Masking the Lightweight Authenticated Ciphers ACORN and Ascon in Software

Alexandre Adomnicai, Jacques J. A. Fournier, and Laurent Masson

Abstract

The ongoing CAESAR competition aims at finding authenticated encryption schemes that offer advantages over AES-GCM for several use-cases, including lightweight applications. ACORN and Ascon are the two finalists for this profile. Our paper compares these two candidates according to their resilience against differential power analysis and their ability to integrate countermeasures against such attacks. Especially, we focus on software implementations and provide benchmarks for several security levels on an ARM Cortex-M3 embedded microprocessor.

Note: Fixed some typos.
