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...
Quantum Meet-in-the-Middle Attacks: Applications to Generic Feistel Constructions
Feistel network Grover's algorithm claw finding algorithm
2017/12/25
This paper shows that quantum computers can significantly speed-up a type of meet-in-the-middle attacks initiated by Demiric and Selçuk (DS-MITM attacks), which is currently one of the most power...
Meet-in-the-Middle Attacks on 3-Line Generalized Feistel Networks
3-line Feistel Meet-in-the-middle attack Key recovery
2017/11/13
In the paper, we study the security of 3-line generalized Feistel network, which is a considerate choice for some special needs, such as designing a 96-bit cipher based on a 32-bit round function. We ...

QARMA Lightweight Tweakable Block Cipher Meet-in-the-Middle Attack
2016/12/29
QARMA is a recently published lightweight tweakable block cipher, which has been used by the ARMv8 architecture to support a software protection feature. In this paper, using the method of MITM, we gi...
Meet-in-the-Middle Attacks on Classes of Contracting and Expanding Feistel Constructions
Unbalanced Feistel Generic Attack Key Recovery
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...

meet-in-the-middle tradeoff collision search
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...
Improved Meet-in-the-Middle Attacks on Reduced-Round Kalyna-128/256 and Kalyna-256/512
Block Cipher Kalyna Meet-in-the-Middle Attack
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
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...
