Improved Preimage Attacks on 4-Round Keccak-224/256
This paper provides an improved preimage attack method on standard 4-round Keccak-224/256. The method is based on the work pioneered by Li and Sun, who design a linear structure of 2-round Keccak-224/256 with 194 degrees of freedom left.

Optimization of preimage resistance on SHA-3 algorithm(SHA-3算法的抗原象攻击性能优化)
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-

Visualizing Elements of Sha[3] in Genus 2 Jacobians [PDF]
Mazur proved that any element xi of order three in the Shafarevich-Tate group of an elliptic curve E over a number field k can be made visible in an abelian surface A in the sense that xi lies in the kernel of the natural homomorphism between the cohomology groups H^1(k,E) -> H^1(k,A).

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2
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

Side-Channel Analysis of Six SHA-3 Candidates [PDF]
In this paper we study six 2nd round SHA-3 candidates from a side-channel cryptanalysis point of view. For each of them, we give the exact procedure and appropriate choice of selection functions to perform the attack. Depending on their inherent structure and the internal primitives used (Sbox, addition or XOR), some schemes are more prone to side ...
