Title:
MATTER: A Wide-Block Tweakable Block Cipher
Authors: Roberto Avanzi, Orr Dunkelman, Kazuhiko Minematsu
Abstract:In this note, we introduce the MATTER Tweakable Block Cipher, designed principally for low latency in low-area hardware implementations, but that can also be implemented in an efficient and compact way in software.
MATTER is a 512-bit wide balanced Feistel network with three to six rounds, using the ASCON permutation as the round function.
The Feistel network defines a keyed, non-tweakable core, which is made tweakable by using the encryption of the tweak as its key.
Key and tweak are 320-bit inputs.
MATTER is particularly suitable for use in an OCB-like mode of operation, with an encrypted checksum for authentication.
