Improved Meet-in-the-Middle Preimage Attacks against AES Hashing Modes
AES MITM preimage
font style='font-size:12px;'>
2019/6/3
Hashing modes are ways to convert a block cipher into a hash function, and those with AES as the underlying block cipher are referred to as AES hashing modes. Sasaki in 2011 introduced the first preim...

Unbalanced Feistel Generic Attack Key Recovery
font style='font-size:12px;'>
2016/12/29
We show generic attacks on unbalanced Feistel ciphers based on the meet-in-the-middle technique. We analyze two general classes of unbalanced Feistel structures, namely contracting Feistels and expand...
A New Algorithm for the Unbalanced Meet-in-the-Middle Problem
meet-in-the-middle tradeoff collision search
font style='font-size:12px;'>
2016/12/10
A collision search for a pair of nn-bit unbalanced functions (one is RR times more expensive than the other) is an instance of the meet-in-the-middle problem, solved with the familiar standard algorit...

Block Cipher Kalyna Meet-in-the-Middle Attack
font style='font-size:12px;'>
2016/7/22
Kalyna is an SPN-based block cipher that was selected during Ukrainian National Public Cryptographic Competition (2007-2010) and its slight modification was approved as the new encryption standard of ...
Automatic Search of Meet-in-the-Middle and Impossible Differential Attacks
automatic search meet-in-the-middle impossible truncated differential
font style='font-size:12px;'>
2016/6/7
Tracking bits through block ciphers and optimizing attacks at hand is one of the tedious task symmetric cryptanalysts have to deal with. It would be nice if a program will automatically handle them at...
