Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE
Security and Communication Networks, Volume 2025, Issue 1, 2025.CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.

Unaligned Rebound Attack: Application to Keccak [PDF]
, 2012 We analyze the internal permutations of Keccak, one of the NIST SHA-3 competition finalists, in regard to differential properties. By carefully studying the elements composing those permutations, we are able to derive most of the best known differential paths for up to 5 rounds. We use these differential paths in a rebound attack setting and adapt this

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 ...

IACR Transactions on Symmetric Cryptology, 2018 We present column parity mixers (CPM), a generalization of the Θ mixing layer that is used in Keccak. Thanks to our description using matrix arithmetic, we can easily derive algebraic, diffusion, and mask propagation properties, leading to a surprising ...

MiMC:Efficient Encryption and Cryptographic Hashing with Minimal Multiplicative Complexity [PDF]
, 2016 We explore cryptographic primitives with low multiplicative complexity. This is motivated by recent progress in practical applications of secure multi-party computation (MPC), fully homomorphic encryption (FHE), and zero-knowledge proofs (ZK) where ...

An on‐chain trading model of real world asset backed digital assets
IET Blockchain, Volume 4, Issue 4, Page 315-323, December 2024.To bridge this gap between off‐chain and on‐chain economic systems, an on‐chain trading model was developed by leveraging key techniques, including HD key derivation, tokenization, oracle, DEX, parallel transactions based on DAG model. Abstract Metaverse is a digital value interaction network based on blockchain technology, with an important economic ...
