Abstract

This paper presents the Subterranean 2.0 cipher suite that can be used for hashing, MAC computation, stream encryption and several types of authenticated encryption schemes. At its core it has a duplex object with a 257-bit state and a lightweight single-round permutation. This makes Subterranean 2.0 very well suited for low-area and low-energy implementations in dedicated hardware.
