2 Cryptanalysis
We distinguish between two cases: results on the complete hash function, and results on underlying building blocks. A description of the following tables is given here.
2.1 Hash function
Here we list results on the actual hash function. The only allowed modification is to change the security parameter.
2.2 Building blocks
Here we list results on underlying building blocks, and the hash function modified by other means than the security parameter.
Note that these results assume more direct control or access over some internal variables (aka. free-start, pseudo, compression function, block cipher, or permutation attacks).
| Type of Analysis | Hash Function Part | Hash Size (n) | Parameters/Variants | Compression Function Calls | Memory Requirements | Reference |
| near-collision | compression | all | example | - | Thomsen | |
| pseudo-collision | hash | all | 23n/8+1 | - | Thomsen | |
| pseudo-preimage | hash | all | 23n/4+1 | - | Thomsen |
