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 ...

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

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.

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...
