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 ...

Neutrality-Based Symmetric Cryptanalysis

Shahram Khazaei

Cryptographic primitives are the basic components of any cryptographic tool. Block ciphers, stream ciphers and hash functions are the fundamental primitives of symmetric cryptography. In symmetric cryptography, the communicating parties perform essentially ...

The Improbable Differential Attack: Cryptanalysis of Reduced Round CLEFIA

Cihangir Tezcan

In this paper we present a new statistical cryptanalytic technique that we call improbable differential cryptanalysis which uses a differential that is less probable when the correct key is used. We provide data complexity estimates for this kind of attack ...

Cryptanalysis of reduced-round MIBS Block cipher

Serge Vaudenay, Jorge Nakahara, Asli Bay

This paper presents the first independent and systematic lin- ear, differential and impossible-differential (ID) cryptanalyses of MIBS, a lightweight block cipher aimed at constrained devices such as RFID tags and sensor networks. Our contributions include ...

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 ZZ232 −1 , which lead to a diﬀerential attack on the full ...

Lightweight Block Ciphers Revisited: Cryptanalysis of Reduced Round PRESENT and HIGHT

Onur Özen, Cihangir Tezcan, Kerem Varici

Design and analysis of lightweight block ciphers have become more popular due to the fact that the future use of block ciphers in ubiquitous devices is generally assumed to be extensive. In this respect, several lightweight block ciphers are designed, of w ...

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 ...

Improved Cryptanalysis of Skein

Willi Meier, Onur Özen, Jean-Philippe Aumasson

The hash function Skein is the submission of Ferguson et al. to the NIST Hash Competition, and is arguably a serious candidate for selection as SHA-3. This paper presents the first third-party analysis of Skein, with an extensive study of its main componen ...
