Improved Linear Cryptanalysis of Reduced-Round MIBS

Serge Vaudenay, Asli Bay, Jialin Huang

MIBS is a 32-round lightweight block cipher with 64-bit block size and two different key sizes, namely 64-bit and 80-bit keys. Bay et al. provided the first impossible differential, differential and linear cryptanalyses of MIBS. Their best attack was a lin ...

Resistance against Adaptive Plaintext-Ciphertext Iterated Distinguishers

Serge Vaudenay, Atefeh Mashatan, Asli Bay

Decorrelation Theory deals with general adversaries who are mounting iterated attacks, i.e., attacks in which an adversary is allowed to make d queries in each iteration with the aim of distinguishing a random cipher C from the ideal random cipher C^*. A b ...

New Impossible Differential and Known-Key Distinguishers for the 3D Cipher

Jorge Nakahara

The contributions of this paper are new 6-round impossible-differential (ID) and 9.75-round known-key distinguishers for the 3D block cipher. The former was constructed using the miss-in-the-middle technique, while the latter with an inside-out technique. ...

On Hiding a Plaintext Length by Preencryption

Serge Vaudenay, Cihangir Tezcan

It is a well known fact that encryption schemes can not hide a plaintext length when it is unbounded. We thus admit that an approximation of it may leak and we focus on hiding its precise value. Some standards such as TLS or SSH offer to do it by applying ...

Statistical Attack on RC4: Distinguishing WPA

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad

In this paper we construct several tools for manipulating pools of biases in the analysis of RC4. Then, we show that optimized strategies can break WEP based on 4000 packets by assuming that the first bytes of plaintext are known for each packet. We descri ...

Improved Linear Differential Attacks on CubeHash

Willi Meier, Shahram Khazaei, Deian Stefan, Simon Knellwolf

This paper presents improved collision attacks on round-reduced variants of the hash function CubeHash, one of the SHA-3 second round candidates. We apply two methods for finding linear differential trails that lead to lower estimated attack complexities w ...

Cryptanalysis of the full MMB block cipher

Jorge Nakahara, Yue Sun

The block cipher MMB was designed by Daemen, Govaerts and Vandewalle, in 1993, as an alternative to the IDEA block cipher. We exploit and describe unusual properties of the modular multiplication in

Z_{2^{32} - 1}

, which lead to a differential attack on ...

Linear (Hull) and Algebraic Cryptanalysis of the Block Cipher PRESENT

Pouyan Sepehrdad, Jorge Nakahara

The contributions of this paper include the first linear hull and a revisit of the algebraic cryptanalysis of reduced-round variants of the block cipher PRESENT, under known-plaintext and ciphertext- only settings. We introduce a pure algebraic cryptanalys ...
