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.
