Three Input Exclusive-OR Gate Support For Boyar-Peralta\u27s Algorithm (Extended Version) [PDF]
, 2021 The linear layer, which is basically a binary non-singular matrix, is an integral part of cipher construction in a lot of private key ciphers. As a result, optimising the linear layer for device implementation has been an important research direction for

On Large Tweaks in Tweakable Even-Mansour with Linear Tweak and Key Mixing [PDF]
, 2023 In this paper, we provide the first analysis of the Iterated Tweakable Even-Mansour cipher with linear tweak and key (or tweakey) mixing, henceforth referred as TEML, for an arbitrary tweak(ey) size kn for all k ≥ 1, and arbitrary number of rounds r ≥ 2.

ZMAC: A Fast Tweakable Block Cipher Mode for Highly Secure Message Authentication [PDF]
, 2017 We propose a new mode of operation called ZMAC allowing to construct a (stateless and deterministic) message authentication code (MAC) from a tweakable block cipher (TBC). When using a TBC with $n$-bit blocks and $t$-bit tweaks, our construction provides

Square Attack on 7-Round Kiasu-BC [PDF]
, 2016 Kiasu-BC is a tweakable block cipher presented within the TWEAKEY framework at AsiaCrypt 2014. Kiasu-BC is almost identical to AES-128, the only difference to AES-128 is the tweak addition, where the 64-bit tweak is xored to the first two rows of every ...

The Tweakable Block Cipher Family QARMAv2 [PDF]
, 2023 We introduce the tweakable block cipher QARMAv2. It is a redesign of QARMA to improve its security bounds and allow for longer tweaks, while keeping similar latency and area. The wider tweak input caters to both specific use cases and the design of modes
