BLAKE2: Simpler, Smaller, Fast as MD5 [chapter]

Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn, Christian Winnerlein
2013 Lecture Notes in Computer Science  
On 64-bit platforms, BLAKE2 is often faster than MD5, yet provides security similar to that of SHA-3.  ...  BLAKE2 has more benefits than just speed: BLAKE2 uses up to 32% less RAM than BLAKE, and comes with a comprehensive tree-hashing mode as well as an efficient MAC mode.  ...  The reference source code package of BLAKE2, as available on, is published under the CC0 licence 7 .  ...

Higher-Order Differential Meet-in-the-middle Preimage Attacks on SHA-1 and BLAKE [chapter]

Thomas Espitau, Pierre-Alain Fouque, Pierre Karpman
2015 Lecture Notes in Computer Science  
Despite being an important technique dating from the mid-90's, this is the first time higherorder differentials have been applied to meet-in-the-middle preimages.  ...  We also apply our framework to the more recent SHA-3 finalist BLAKE and its newer variant BLAKE2, and give an attack for a 2.75-round preimage with padding, and a 7.5-round pseudo-preimage on the compression  ...  It combines a compression function which is a block cipher with 512-bit keys and 160-bit messages used in Davies-Meyer mode with a Merkle-Damgård mode of operation [14, Chap. 9].  ...

On the Resilience of Even-Mansour to Invariant Permutations

Bart Mennink, Samuel Neves
2021 Designs, Codes and Cryptography  
The attacks do not invalidate the security of the permutations themselves, but rather they demonstrate the tightness of our bounds and confirm that care should be taken when employing a cryptographic primitive  ...  We first formalize the use of invariant cryptographic permutations from a security perspective, and analyze the Even-Mansour block cipher construction.  ...  Other permutations, often single-purpose components of larger modes of operation, decide to omit such round constants, and let the mode of operation ensure that "bad" states are never reached.  ...
