Side-Channel Attack Using Meet-in-the-Middle Technique

The Computer Journal, 2009
In this paper, we introduce a new side-channel attack using block cipher cryptanalysis named a meet-in-the-middle attack. Using our new side-channel technique we show that advanced encryption standard (AES) with reduced 10 masked rounds is broken, which is faster than the exhaustive key search attack. This implies that one has to mask the entire rounds

Automatic Search of Meet-in-the-Middle and Impossible Differential Attacks

2016
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 least for well-known attack techniques, so that cryptanalysts will only focus on finding new attacks.

Meet-in-the-Middle Attacks on Reduced-Round Hierocrypt-3

2015
Hierocrypt-3 is an SPN-based block cipher designed by Toshiba Corporation. It operates on 128-bit state using either 128, 192 or 256-bit key. In this paper, we present two meet-in-the-middle attacks in the single-key setting on the 4-round reduced Hierocrypt-3 with 256-bit key. The first attack is based on the differential enumeration approach where we

Improved Meet-in-the-Middle Attacks on Reduced Round Kuznyechik

2018
Kuznyechik is an SPN block cipher that has been chosen recently to be standardized by the Russian federation as a new GOST cipher. The cipher employs a 256-bit key which is used to generate ten 128-bit round keys. The encryption procedure updates the 16-byte state by iterating the round function for nine rounds.

Improved Meet-in-the-Middle Attacks on Round-Reduced ARIA

2015
ARIA is a 128-bit SPN block cipher selected as a Korean standard. This paper processes meet-in-the-middle attacks on reduced-round ARIA. Some 4-round and 5-round significant distinguishing properties which involve much fewer bytes parameters are proposed.

Match Box Meet-in-the-Middle Attack Against KATAN

2015
Recent years have seen considerable interest in lightweight cryptography. One particular consequence is a renewed study of meet-in-the-middle attacks, which aim to exploit the relatively simple key schedules often encountered in lightweight ciphers. In this paper we propose a new technique to extend the number of rounds covered by a meet-in-the-middle ...
