The Legendre Symbol and the Modulo-2 Operator in Symmetric Schemes over Fnp
Motivated by modern cryptographic use cases such as multi-party computation (MPC), homomorphic encryption (HE), and zero-knowledge (ZK) protocols, several symmetric schemes that are efficient in these scenarios have recently been proposed in the ...

Exploiting Weak Diffusion of Gimli: Improved Distinguishers and Preimage Attacks
The Gimli permutation proposed in CHES 2017 was designed for cross-platform performance. One main strategy to achieve such a goal is to utilize a sparse linear layer (Small-Swap and Big-Swap), which occurs every two rounds.

We propose a preimage attack against cryptographic hash functions based on the speedup enabled by quantum computing. Preimage resistance is a fundamental property cryptographic hash functions must possess. The motivation behind this work relies in the lack of conventional attacks against newly introduced hash schemes such as the recently elected SHA-3 ...

Improved preimage and pseudo-collision attacks on SM3 hash function
A preimage attack on 32-step SM3 hash function and a pseudo-collision attack on 33-step SM3 hash function respectively were shown.32-step preimage attack was based on the differential meet-in-the-middle and biclique technique,while the previously known ...

In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function ...

A second preimage attack on zipper hash
AbstractThe zipper hash utilizes two‐pass hashing to strengthen the iterated hash functions against the generic attack. In this paper, we analyze the features of zipper hash and several existing generic attacks on hash functions. A new tree structure called inverse‐diamond, which starts from one fixed point and ends with many points, is exploited to ...

Preimage and pseudo collision attacks on round-reduced DHA-256 hash function
A preimage attack on DHA-256 hash function reduced to 37-round and a pseudo collision attack on the func-tion reduced to 39-round were proposed respectively.Based on the meet-in-the-middle attack,the Biclique technique was used to improve the preimage ...

Preimage Attacks on the Round-reduced Keccak with Cross-linear Structures
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
