A Meet-in-the-Middle Attack on 8-Round AES [PDF]
, 2008 We present a 5-round distinguisher for AES. We exploit this distinguisher to develop a meet-in-the-middle attack on 7 rounds of AES-192 and 8 rounds of AES-256. We also give a time-memory tradeoff generalization of the basic attack which gives a better balancing between different costs of the attack.

A novel security analysis for a new NTRU variant with additional private key [PDF]
International Journal of Data and Network Science, 2023 This paper proposes a new variant of NTRU with a slightly different critical formulation. The significance of this new variant is that it requires an additional private key to provide a tighter scheme.

Meet-in-the-Middle Attacks on Reduced-Round XTEA [PDF]
, 2011 Summary: The block cipher GOST (GOST 28147-89) is a Russian standard for encryption and message authentication that is included in OpenSSL 1.0.0. In this paper, we present meet-in-the-middle attacks on several block ciphers, each consisting of 22 or fewer rounds of GOST.

Improved meet-in-the-middle attacks on reduced-round tweakable block ciphers Kiasu-BC and Deoxys-BC
Journal of King Saud University: Computer and Information Sciences, 2023 Tweakable block ciphers Kiasu-BC and Deoxys-BC are both the internal block ciphers of the candidates for the CAESAR authenticated encryption competition.

Improved Meet-in-the-Middle Attacks on Crypton and mCrypton
KSII Transactions on Internet and Information Systems, 2017 This study presents several meet‐in‐the‐middle attacks on reduced‐round Crypton and mCrypton block ciphers. Using the generalised δ ‐set, the authors construct 5‐round distinguishers on Crypton and mCrypton.

Meet-in-the-Middle Attacks on SHA-3 Candidates [PDF]
, 2009 We present preimage attacks on the SHA-3 candidates Boole, EnRUPT, Edon-R, and Sarmal, which are found to be vulnerable against a meet-in-the-middle attack. The idea is to invert (or partially invert) the compression function and to exploit its non-randomness. To launch an attack on a large internal state we manipulate the message blocks to be injected

Meet-in-the-Middle Attacks on Generic Feistel Constructions [PDF]
, 2014 We show key recovery attacks on generic balanced Feistel ciphers. The analysis is based on the meet-in-the-middle technique and exploits truncated differentials that are present in the ciphers due to the Feistel construction. Depending on the type of round function, we differentiate and show attacks on two types of Feistels.

Improved Meet-in-the-Middle Attacks on AES
, 2009 We improve the existing distinguishers of AES. Our work is mainly built upon the works by Gilbert& Miner [17] and Demirci & Selcuk [14]. We find out that some part of the inner encryption function of AES can be expressed with relatively few constants under certain conditions. These new distinguishers are exploited to develop a meet-in-the-middle attack

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding
Tongxin xuebao, 2014 The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.
