Rebound Distinguishers: Results on the Full Whirlpool Compression Function
TL;DR: In this paper, the authors presented a distinguishing attack on the full compression function of Whirlpool hash function, which is a hash function based on a block cipher that can be seen as a scaled up variant of the AES.
Book ChapterDOI
Towards Fresh and Hybrid Re-Keying Schemes with Beyond Birthday Security
TL;DR: The reasoning extends to hybrid schemes, where the communication party to protect against side-channel attacks is stateful, and is illustrated by describing a collision attack against an example of a hybrid scheme patented by Kocher, and presenting a tweak leading to beyond birthday security.

Higher-Order Differential Attack on Reduced SHA-256.
Mario Lamberger,Florian Mendel +1 more
TL;DR: In this paper, a second-order differential attack on the SHA-256 compression function was presented, which reduced the complexity of the algorithm to 46 out of 64 steps, which is the fastest known algorithm.
Book ChapterDOI
Cryptanalysis of Ascon
TL;DR: The first results regarding linear cryptanalysis of Ascon are presented, improve upon the results of the designers regarding differential cryptanalysis, and bounds on the minimum number of (linearly and differentially) active S-boxes for the Ascon permutation are proved.
Book ChapterDOI
The impact of carries on the complexity of collision attacks on SHA-1
TL;DR: It is shown that the attack complexity for SHA-1 is slightly lower than estimated in all published work to date, and it is pointed out that it is more accurate to consider probabilities instead of conditions.
