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: r/b = 16/32 (n=224,256); 16/32 (n=384,512)

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/Variants Compression Function Calls Memory Requirements Reference
preimage 384,512 r/32 2383.7 - Ferguson,Lucks,McKay
preimage 384,512 r/33 2257.6 - Ferguson,Lucks,McKay
collision 512 7/64 2203 - Brier,Khazaei,Meier,Peyrin
collision all 4/48 example (237) - Brier,Khazaei,Meier,Peyrin
collision all 4/64 example (234) - Brier,Khazaei,Meier,Peyrin
collision all 3/64 example (224) - Brier,Khazaei,Meier,Peyrin
collision 512 2/2 2196 - Brier,Khazaei,Meier,Peyrin
collision 512 5/64 2231 - Brier,Peyrin
collision all 3/64 289 - Brier,Peyrin
collision 512 4/3 2207 - Brier,Peyrin
collision 384,512 4/4 2189 - Brier,Peyrin
collision all 2/3 246 - Brier,Peyrin
collision 512 2/4 example - Brier,Peyrin
collision 512 1/45, 2/89 example - Dai
collision 512 2/120 example - Aumasson
preimage 512 r/8 2480 - Khovratovich,Nikolic',Weinmann
preimage 512 r/4 2496 - Khovratovich,Nikolic',Weinmann
preimage 512 r/1 (round 1) 2511 2508 Khovratovich,Nikolic',Weinmann
preimage all r/b 2513-4b - Aumasson,Meier,Naya-Plasencia,Peyrin
collision all r/b 2521-4b-log b - submission document
preimage all r/b 2522-4b-log b - submission document


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
quantum preimage hash 512 2192 - Leurent
distinguisher permutation all 14 rounds 2812 - Ashur,Dunkelman
distinguisher permutation all 11 rounds 2470 - Ashur,Dunkelman
observations hash all - - Kaminsky
observations hash all - - Bloom,Kaminsky
multi-collision hash all 2513-4b - Aumasson,Meier,Naya-Plasencia,Peyrin
observations permutation all - - Aumasson,Meier,Naya-Plasencia,Peyrin
