In 2012, NIST standardized SHA-512/224 and SHA-512/256, two truncated variants of SHA-512, in FIPS 180-4. These two hash functions are faster than SHA-224 and SHA-256 on 64-bit platforms, while mainta...
Branching Heuristics in Differential Collision Search with Applications to SHA-512
hash functions cryptanalysis SHA-512

In this work, we present practical semi-free-start collisions for SHA-512 on up to 38 (out of 80) steps with complexity 240.5 . The best previously published result was on 24 steps. The attack is b...
SHA-2 (SHA-224, SHA-256, SHA-384 and SHA-512) is hash
function family issued by the National Institute of Standards and Technology
(NIST) in 2002 and is widely used all over the world. In this work,...

With the emergence of pervasive 64 bit computing we observe that it is more cost effective to compute a SHA-512 than it is to compute a SHA-256 over a given size of data. We propose a standard way to ...
Preimage Attacks on 41-Step SHA-256 and 46-Step SHA-512
SHA-256 SHA-512 hash preimage attack
2009/10/9
In this paper, we propose preimage attacks on 41-step SHA-256 and 46-step SHA-512,
which drastically increase the number of attacked steps compared to the best previous preimage attack working for on...
