New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160 [PDF]

IACR Transactions on Symmetric Cryptology, 2019
RIPEMD-160 is a hash function published in 1996, which shares similarities with other hash functions designed in this time-period like MD4, MD5 and SHA-1.

Automating Collision Attacks on RIPEMD-160

IACR Transactions on Symmetric Cryptology, 2023
As an ISO/IEC standard, the hash function RIPEMD-160 has been used to generate the Bitcoin address with SHA-256. However, due to the complex doublebranch structure of RIPEMD-160, the best collision attack only reaches 36 out of 80 steps of RIPEMD-160 ...

Search framework for neutral bits and boomerangs in SHA‐1 collision attacks

IET Information Security, 2023
Neutral bits and boomerangs are key techniques for accelerating collision search in SHA‐1 attacks. The current acceleration techniques for SHA‐1 near‐collision attacks are reviewed and a generic search framework for neutral bits and boomerangs is ...

Numerical simulation of collision-free near-shortest path generation for Dubins vehicle via Hamilton–Jacobi–Bellman equation: A case study

Cogent Engineering, 2020
Motivated by modeling an unmanned aerial vehicle at a constant altitude plane above ground level as Dubins vehicle with signed upper-bounded curvature as constrained input and the flight path as Dubins path, the class of flight paths we study is ...

Cryptanalysis of 48-step RIPEMD-160

IACR Transactions on Symmetric Cryptology, 2017
In this paper, we show how to theoretically compute the step differential probability of RIPEMD-160 under the condition that only one internal variable contains difference and the difference is a power of 2.

SAT-Based Space Partitioning and Applications to Ascon-Hash256 Cryptanalysis

IACR Transactions on Symmetric Cryptology
We introduce an efficient SAT-based space partitioning technique that enables systematic exploration of large search spaces in cryptanalysis. The approach divides complex search spaces into manageable subsets through combinatorial necklace generation ...

Opening the Blackbox: Collision Attacks on Round-Reduced Tip5, Tip4, Tip4’ and Monolith

IACR Transactions on Symmetric Cryptology
A new design strategy for ZK-friendly hash functions has emerged since the proposal of Reinforced Concrete at CCS 2022, which is based on the hybrid use of two types of nonlinear transforms: the composition of some small-scale lookup tables (e.g., 7-bit
