2 Cryptanalysis
We distinguish between two cases: results on the complete hash function, and results on underlying building blocks.
A description of the tables is given here.
Recommended security parameters: (k,r,t) = (2,5,13) for (n=224,256); (k,r,t) = (3,5,13) for (n=384); (k,r,t) = (4,8,13) for (n=512)
2.1 Hash function
Here we list results on the hash function according to the NIST requirements. The only allowed modification is to change the security parameter.
Type of Analysis | Hash Size (n) | Parameters | Compression Function Calls | Memory Requirements | Reference |
internal collision | 256 | (2,5,13) | 2352 | 2352 | Khovratovich |
internal collision | 512 | (4,8,13) | 2480 | 2480 | Khovratovich |
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).
