Multimixer-128: Universal Keyed Hashing Based on Integer Multiplication
IACR Transactions on Symmetric Cryptology, 2023 In this paper we introduce a new keyed hash function based on 32-bit integer multiplication that we call Multimixer-128. In our approach, we follow the key-then-hash parallel paradigm. So, we first add a variable length input message to a secret key and

BipBip: A Low-Latency Tweakable Block Cipher with Small Dimensions
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Recently, a memory safety concept called Cryptographic Capability Computing (C3) has been proposed. C3 is the first memory safety mechanism that works without requiring extra storage for metadata and hence, has the potential to significantly enhance the

Deck-Based Wide Block Cipher Modes and an Exposition of the Blinded Keyed Hashing Model
IACR Transactions on Symmetric Cryptology, 2020 We present two tweakable wide block cipher modes from doubly-extendable cryptographic keyed (deck) functions and a keyed hash function: double-decker and docked-double-decker.

Errata to Sound Hashing Modes of Arbitrary Functions, Permutations, and Block Ciphers
IACR Transactions on Symmetric Cryptology, 2020 In ToSC 2018(4), Daemen et al. performed an in-depth investigation of sound hashing modes based on arbitrary functions, permutations, or block ciphers. However, for the case of invertible primitives, there is a glitch.

Algebraic and Higher-Order Differential Cryptanalysis of Pyjamask-96
IACR Transactions on Symmetric Cryptology, 2020 Cryptographic competitions, like the ongoing NIST call for lightweight cryptography, always provide a thriving research environment, where new interesting ideas are proposed and new cryptographic insights are made. One proposal for this NIST call that is

Security of the Suffix Keyed Sponge
IACR Transactions on Symmetric Cryptology, 2020 We formalize and analyze the general suffix keyed sponge construction, a pseudorandom function built on top of a cryptographic permutation. The construction hashes its data using the (keyless) sponge construction, transforms part of the state using the ...

Practical Evaluation of Protected Residue Number System Scalar Multiplication
Transactions on Cryptographic Hardware and Embedded Systems, 2018 The Residue Number System (RNS) arithmetic is gaining grounds in public key cryptography, because it offers fast, efficient and secure implementations over large prime fields or rings of integers.
