CUBE Cipher: A Family of Quasi-Involutive Block Ciphers Easy to Mask

摘要

This paper proposes a new quasi-involutive lightweight design called CUBE cipher family. The design has been carefully chosen to be easily masked. The basic building block is a cube of size nxnxnon which are applied SPN transformations followed by a cube mapping. We analyze the proposals from a security point of view and provide a full hardware implementation analysis.
