An Improved Impossible Differential Attack on MISTY1
MISTY1 is a Feistel block cipher that received a great deal of cryptographic attention. Its recursive structure, as well as the added FL layers, have been successful in thwarting v...

KFC - The Krazy Feistel Cipher
We introduce KFC, a block cipher based on a three round Feistel scheme. Each of the three round functions has an SPN-like structure for which we can either compute or bound the adv...

Hash Functions and the (Amplified) Boomerang Attack
Abstract. Since Crypto 2004, hash functions have been the target of many attacks which showed that several well-known functions such as SHA-0 or MD5 can no longer be considered sec...

Security Analysis of the GF-NLFSR Structure and Four-Cell Block Cipher
The overall structure is one of the most important properties of block ciphers. At present, the most common structures include Feistel structure, SP structure, MISTY structure, L-M...

The Boomerang Attack on 5 and 6-Round Reduced AES
In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key searc...
