Optimized Software Implementation of Keccak, Kyber, and Dilithium on RV{32,64}IM{B}{V}

Transactions on Cryptographic Hardware and Embedded Systems
With the standardization of NIST post-quantum cryptographic (PQC) schemes, optimizing these PQC schemes across various platforms presents significant research value. While most existing software implementation efforts have concentrated on ARM platforms,

Simulating SASCA on Keccak: Security Implications for Post-Quantum Cryptographic Schemes

International Conference on Security and Cryptography
: Keccak is a standard hashing algorithm that is used in cryptographic protocols as Pseudo Random Functions (PRF), as Pseudo Random Number Generator (PRNG), to check data integrity or to create a Hash-based Message Authentication Code (HMAC).

Highly Efficient Symmetric Key Based Authentication and Key Agreement Protocol Using Keccak [PDF]

Sensors, 2020
Efficient authentication and key agreement protocols between two entities are required in many application areas. In particular, for client–server type of architectures, the client is mostly represented by a constrained device and thus highly efficient ...

The Road from Panama to Keccak via RadioGatún

, 2009
In this presentation, we explain the design choices of Panama [1] and RadioGatun [2], which lead to Keccak [3]. After a brief recall of Panama, RadioGatun and the trail backtracking cost, we focus on three important aspects. First, we explain the role of the belt in the light of differential trails. Second, we discuss the relative advantages of a block

New Conditional Cube Attack on Keccak Keyed Modes

IACR Transactions on Symmetric Cryptology, 2019
The conditional cube attack on round-reduced Keccak keyed modes was proposed by Huang et al. at EUROCRYPT 2017. In their attack, a conditional cube variable was introduced, whose diffusion was significantly reduced by certain key bit conditions.

New techniques for trail bounds and application to differential trails in Keccak

IACR Transactions on Symmetric Cryptology, 2017
We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as ordered lists of basic components in order to arrange
