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 ...

Stochastic Collision Attack

IEEE Transactions on Information Forensics and Security, 2017
On the one hand, collision attacks have been introduced in the context of side-channel analysis for attackers who exploit repeated code with the same data without having any knowledge of the leakage model. On the other hand, stochastic attacks have been introduced to recover leakage models of internally processed intermediate secret variables.

Algebraic Collision Attacks on Keccak

IACR 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

Internal collision attack on Maraca [PDF]

, 2009
We present an internal collision attack against the new hash function Maraca which has been submitted to the SHA-3 competition. This attack requires 2^{237} calls to the round function and its complexity is lower than the complexity of the generic collision attack when the length of the message digest is greater than or equal to 512.

Instruction-Fetching Attack and Practice in Collision Fault Attack on AES

Symmetry, 2022
A Fault Attack (FA) is performed mainly under the data corruption model and poses a threat to security chips. Instruction corruption can enact the same purpose at the behavioral level, which is produced by interfering with the instruction system. Laser Fault Injection (LFI) on program memory during the instruction-fetching process, which we refer to as

Collision Attack on 5 Rounds of Grøstl [PDF]

, 2015
In this article, we describe a novel collision attack for up to 5 rounds of the Grostl hash function. This significantly improves upon the best previously published results on 3 rounds. By using a new type of differential trail spanning over more than one message block we are able to construct collisions for Grostl-256 on 4 and 5 rounds with complexity

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

Jisuanji 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.
