Duel of the Titans: The Romulus and Remus Families of Lightweight AEAD Algorithms
IACR Transactions on Symmetric Cryptology, 2020 In this article, we propose two new families of very lightweight and efficient authenticated encryption with associated data (AEAD) modes, Romulus and Remus, that provide security beyond the birthday bound with respect to the block-length n.

Almost-Minimal-Round BBB-Secure Tweakable Key-Alternating Feistel Block Cipher [PDF]
Symmetry, 2021 This paper focuses on designing a tweakable block cipher via by tweaking the Key-Alternating Feistel (KAF for short) construction. Very recently Yan et al. published a tweakable KAF construction. It provides a birthday-bound security with 4 rounds and Beyond-Birthday-Bound (BBB for short) security with 10 rounds. Following their work, we further reduce

Optimization of Tree Modes for Parallel Hash Functions: A Case Study [PDF]
, 2017 This paper focuses on parallel hash functions based on tree modes of operation for an inner Variable-Input-Length function. This inner function can be either a single-block-length (SBL) and prefix-free MD hash function, or a sponge-based hash function ...

Boomerang Connectivity Table:A New Cryptanalysis Tool [PDF]
, 2018 A boomerang attack is a cryptanalysis framework that regards a block cipher $E$ as the composition of two sub-ciphers $E_1\circ E_0$ and builds a particular characteristic for $E$ with probability $p^2q^2$ by combining differential characteristics for ...

Forking Tweakable Even-Mansour Ciphers
IACR Transactions on Symmetric Cryptology, 2020 A forkcipher is a keyed, tweakable function mapping an n-bit input to a 2nbit output, which is equivalent to concatenating two outputs from two permutations.

Zero-Correlation Attacks on Tweakable Block Ciphers with Linear Tweakey Expansion [PDF]
IACR Transactions on Symmetric Cryptology, 2019 The design and analysis of dedicated tweakable block ciphers is a quite recent and very active research field that provides an ongoing stream of new insights. For instance, results of Kranz, Leander, and Wiemer from FSE 2017 show that the addition of a tweak using a linear tweak schedule does not introduce new linear characteristics.

Re-Keying Scheme Revisited: Security Model and Instantiations
Applied Sciences, 2019 The re-keying scheme is a variant of the symmetric encryption scheme where a sender (respectively, receiver) encrypts (respectively, decrypts) plaintext with a temporal session key derived from a master secret key and publicly-shared randomness.
