Improved Preimage Attacks on 3-Round Keccak-224/256
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we provide an improved method on preimage attacks of standard 3-round Keccak-224/256. Our method is based on the work by Li and Sun. Their strategy is to find a 2-block preimage instead of a 1-block one by constructing the first and second

Preimage Attacks on the Round-reduced Keccak with Cross-linear Structures
IACR Transactions on Symmetric Cryptology, 2017 In this paper, based on the work pioneered by Aumasson and Meier, Dinur et al., and Guo et al., we construct some new delicate structures from the roundreduced versions of Keccakhash function family. The new constructed structures are called cross-linear

Classification of the SHA-3 Candidates
, 2009 In this note we give an overview on the current state of the SHA-3 candidates. First, we classify all publicly known candidates and, second, we outline and summarize the performance data as given in the candidates documentation for $64$-bit and $32$-bit implementations. We define performance classes and classify the hash algorithms.

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-

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2
Transactions on Cryptographic Hardware and Embedded Systems, 2023 In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2. We provide full mathematical analysis of
