Meet-in-the-Middle Attacks on Reduced Round Piccolo
Science China Information Sciences, 2016Piccolo is a lightweight block cipher designed by Sony Corporation and published in CHES 2011. It inherits the Generalized Feistel Network GFN structure and operates on a 64-bit state. It has two versions; Piccolo-80 and Piccolo-128 with 80-bit and 128-bit keys, respectively.

Meet-in-the-Middle Attacks on Round-Reduced Khudra
2015Khudra is a hardware-oriented lightweight block cipher that is designed to run efficiently on Field Programmable Gate Arrays. It employs an 18-rounds Generalized type-2 Feistel Structure with a 64-bit block length and an 80-bit key. In this paper, we present Meet-in-the-Middle MitM attacks on 13 and 14 round-reduced Khudra.

A meet-in-the-middle attack on the LBlock cipher
IEEE Conference Anthology, 2013LBlock is a new lightweight Block cipher which was proposed by Wu and Zhang at ACNS2011. The block size of LBlock is 64 bits and its key size is 80 bits. It was reported that the cipher is very suitable for many resource constrained environments (for instance RFID and sensor networking) which usually have weak computation ability, strict power ...

Meet-in-the-middle attack on digital signature schemes
2006The meet-in-the-middle attack can be used for forging signatures on mixed-type digital signature schemes, and takes less time than an exhaustive attack. This paper formulates a meet-in-the-middle attack on mixed-type digital signature schemes, shows the necessary conditions for success, and discusses the relationships between computational and space ...

Side-Channel Attack Using Meet-in-the-Middle Technique
The Computer Journal, 2009In 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

Meet-in-the-Middle Attacks on Reduced-Round Hierocrypt-3
2015Hierocrypt-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

Automatic Search of Meet-in-the-Middle and Impossible Differential Attacks
2016Tracking 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.

Improved Meet-in-the-Middle Attacks on Reduced Round Kuznyechik
2018Kuznyechik 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.
