GPU Accelerated Keccak (SHA3) Algorithm
CoRR, 2019 Hash functions like SHA-1 or MD5 are one of the most important cryptographic primitives, especially in the field of information integrity. Considering the fact that increasing methods have been proposed to break these hash algorithms, a competition for a new family of hash functions was held by the US National Institute of Standards and Technology ...

Towards quantum‐safe blockchain: Exploration of PQC and public‐key recovery on embedded systems
IET Blockchain, Volume 5, Issue 1, January/December 2025.This paper addresses the need for quantum‐safe blockchain solutions specifically for embedded systems by integrating Post‐Quantum Cryptography (PQC) into blockchain frameworks. We propose a quantum‐secure blockchain architecture using NIST‐standardized PQC algorithms, finding Falcon‐512 to be optimal for embedded environments due to its security and ...

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 ...

A Fast Search Method for 3‐Share Second‐Order Masking Schemes for Lightweight S‐Boxes
IET Information Security, Volume 2025, Issue 1, 2025.Masking schemes are widely adopted strategies for countering side‐channel analysis (SCA) attacks. The initial hardware masking strategy, threshold implementation (TI), provides robust security against glitches in hardware platforms. The minimum number of shares required for a TI scheme depends not only on the desired security order but also on the ...

Optimization of preimage resistance on SHA-3 algorithm(SHA-3算法的抗原象攻击性能优化)
Zhejiang Daxue xuebao. Lixue ban, 2016 通过对SHA-3算法置换函数Keccak-f的线性性质以及缩减轮数的Keccak杂凑函数原象攻击的研究，提出了 SHA-3算法的抗原象攻击性能优化设计方案.首先结合Keccak杂凑函数的差分特点和θ置换函数的奇偶性质，分析了基于CP-kernel的SHA-3算法原象攻击；然后针对目前实施原象攻击的方法，在θ置换函数运算后异或随机数以打乱其汉明重量，改变CP-kernel的校验性质，阻止攻击者利用中间相遇的方法寻找原象，提高了 SHA-3 算法的抗原象攻击能力；最后利用VHDL硬件语言实现抗原象攻击SHA-
