In this work, we present several new generic second-preimage attacks on hash functions. Our first attack is based on the herding attack and applies to various Merkle-Damgard-based iterative hash functions. Compared to the previously known long-message second-preimage attacks, our attack offers ...
Preimage attackGOST R 34.11-2012StribogSummary: In August 2012, the Stribog hash function was selected as the new Russian cryptographic hash standard (GOST R 34.11-2012). Stribog employs twelve rounds of an AES-based compression function operating in Miyaguchi-Preneel mode. In this paper, we ...
A hash function f can be thought of as an operation on bits X to produce output bits Y: f(X) = Y. Given knowledge of Y and how f works, we want to find some bits X' such that f(X') = Y. This is commonly known as a preimage attack. Note that X does not necessarily need...

A preimage attack on hash functions tries to find a message that has a specific hash value. A cryptographic hash function should resist attacks on its preimage. The current paper presents a new quantum algorithm for hash preimage attacks, which can break the preimage resistance with circuit ...
second preimage attackThe zipper hash utilizes two-pass hashing to strengthen the iterated hash functions against the generic attack. In this paper, we analyze the features of zipper hash and several existing generic attacks on hash functions. A new tree structure called inverse-diamond, which ...
Preimage AttackHash FunctionMeet-in-the-middleIn this paper, we present the preimage attacks on step-reduced ARIRANG and PKC98-Hash. Our attacks find the preimages of 35 steps out of 40 steps of ARIRANG and 80 steps out of 96 steps of PKC98-Hash, faster than the brute force attack. ...
We recommend that FFT-Hash can not be used in case of the output size less than 256 bits because the full security against the preimage attack are crucial in such a short output size. And also we should not chop the hash output in order to get a short hash output like SHA-224 and ...
