Automating Collision Attacks on RIPEMD-160

open access: diamondIACR 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 ...

Algebraic Collision Attacks on Keccak

open access: diamondIACR Transactions on Symmetric Cryptology, 2021
In this paper, we analyze the collision resistance of the two smallest versions of Keccak which have a width of 200 and 400 bits respectively. We show that algebraic and linearization techniques can serve collision cryptanalysis by using some interesting

Chosen-Key Distinguishers on 12-Round Feistel-SP and 11-Round Collision Attacks on Its Hashing Modes

open access: greenIACR Transactions on Symmetric Cryptology, 2016
Since Knudsen and Rijmen proposed the known-key attacks in ASIACRYPT 2007, the open-key model becomes more and more popular. As the other component of the open-key model, chosen-key model was applied to the full attacks on AES-256 by Biryukov et al.

A Symbolic Intruder Model for Hash-Collision Attacks [PDF]

open access: green, 2006
In the recent years, several practical methods have been published to compute collisions on some commonly used hash functions. In this paper we present a method to take into account, at the symbolic level, that an intruder actively attacking a protocol ...

Optimizing Fast Near Collision Attack on Grain Using Linear Programming [PDF]

open access: goldIEEE Access, 2019
In 2018, an attack named fast-near-collision attack (FNCA) was proposed, which is an improved version of near-collision attack (NCA) on Grain-v1, one of the three hardware-oriented finalists of the eSTREAM project.

Preimage and collision attacks on reduced Ascon using algebraic strategies [PDF]

open access: diamondCybersecurity
Ascon, a family of algorithms that supports hashing and authenticated encryption, is the winner of the NIST Lightweight Cryptography Project. In this paper, we propose an improved preimage attack against 2-round Ascon-XOF-64 with a complexity of $$2^{33}$

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

open access: diamondIACR 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

Random Plaintext Collision Attack Against AES Algorithm with Reused Masks [PDF]

open access: yesJisuanji gongcheng, 2022
The topic of side-channel attacks is popular in cryptographic research. As an important branch of side-channel attacks, collision attacks can effectively extract information related to intermediate values from energy leakage.

Deep Learning Side-Channel Collision Attack

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2023
With the breakthrough of Deep Neural Networks, many fields benefited from its enormously increasing performance. Although there is an increasing trend to utilize Deep Learning (DL) for Side-Channel Analysis (SCA) attacks, previous works made specific ...
