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

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.

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

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.

Compact Dilithium Implementations on Cortex-M3 and Cortex-M4

Transactions on Cryptographic Hardware and Embedded Systems, 2020
We present implementations of the lattice-based digital signature scheme Dilithium for ARM Cortex-M3 and ARM Cortex-M4. Dilithium is one of the three signature finalists of the NIST post-quantum cryptography competition.

Security Digital Evidence [PDF]

2010 Fifth IEEE International Workshop on Systematic Approaches to Digital Forensic Engineering, 2010
Non-repudiation of digital evidence is required by various use cases in today’s business cases for example in the area of medical products but also in public use cases like congestion charges. These use cases have in common that at a certain time an evidence record is generated to attest for the occurrence of a certain event.

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 ...
