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

IACR Transactions on Symmetric Cryptology, 2020 Fast Near collision attacks on the stream ciphers Grain v1 and A5/1 were presented at Eurocrypt 2018 and Asiacrypt 2019 respectively. They use the fact that the entire internal state can be split into two parts so that the second part can be recovered from the first one which can be found using the keystream prefix and some guesses of the key materials.

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 ...

Quantum Free-Start Collision Attacks on Double Block Length Hashing with Round-Reduced AES-256
IACR Transactions on Symmetric Cryptology, 2021 Recently, Hosoyamada and Sasaki (EUROCRYPT 2020), and Xiaoyang Dong et al. (ASIACRYPT 2020) proposed quantum collision attacks against AES-like hashing modes AES-MMO and AES-MP.

Instruction-Fetching Attack and Practice in Collision Fault Attack on AES [PDF]
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

Two Improved Multiple‐Differential Collision Attacks [PDF]
Mathematical Problems in Engineering, 2014 In CHES 2008, Bogdanov proposed multiple‐differential collision attacks which could be applied to the power analysis attacks on practical cryptographic systems. However, due to the effect of countermeasures on FPGA, there are some difficulties during the collision detection, such as local high noise and the lack of sampling points.

Deep Learning Side-Channel Collision Attack
Transactions 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 ...

Preimage and Collision Attacks on MD2 [PDF]
, 2005 This paper contains several attacks on the hash function MD2 which has a hash code size of 128 bits. At Asiacrypt 2004 Muller presents the first known preimage attack on MD2. The time complexity of the attack is about 2104 and the preimages consist always of 128 blocks.

Understanding realistic attacks on airborne collision avoidance systems [PDF]
Journal of Transportation Security, 2022 AbstractAirborne collision avoidance systems provide an onboard safety net should normal air traffic control procedures fail to keep aircraft separated. These systems are widely deployed and have been constantly refined over the past three decades, usually in response to near misses or mid-air collisions.
