In this paper we study the long standing problem of information extraction from multiple linear approximations. We develop a formal statistical framework for block cipher attacks based on this technique and derive explicit and compact gain formulas for generalized versions of Matsui’s Algorithm 1 and Algorithm 2. The theoretical framework allows both approaches to be treated in a unified way, and predicts significantly improved attack complexities compared to current linear attacks using a…

Various attacks against reduced-round versions of the AES candidate Serpent are presented to confirm the significant reductions of the attacks data complexity that can be obtained from multiple linear approximations.
Multidimensional Linear Cryptanalysis of Reduced Round Serpent
- Computer Science, MathematicsACISP

A new truly multidimensional approach to generalise Matsui's Algorithm 1.0 is presented and it is shown that the multiddimensional approach is more effective in recovering key bits correctly than the previous methods that use a multiple of one-dimensional linear approximations.

This paper presents a 9-round linear characteristic with probability $\frac{1}{2}+2^{-50}$ that involves a reduction of the estimated data complexity of the best reported attack by a factor of 16 and investigates the possibility to take advantage of multiple linear approximations for improving the linear cryptanalysis of Serpent.
A Statistical Saturation Attack against the Block Cipher PRESENT
- Computer Science, MathematicsCT-RSA

A statistical saturation attack that combines previously introduced cryptanalysis techniques against block ciphers and extracts information about the key by observing non-uniform distributions in the ciphertexts and improves previous (linear, differential) cryptanalysis results.

An application of the new algorithm results in the first-known near-practical key recovery attack on the shrinking generator with the parameters suggested by Krawczyk in 1994.
Collisions on SHA-0 in One Hour

This paper shows that the previous perturbation vectors used in all known attacks are not optimal and provides a new 2-block one and is able to produce the best collision attack against SHA-0 so far, with a measured complexity of 233,6hash function calls.
Algebraic Cryptanalysis of 58-Round SHA-1

- 2007
The aim of this article is to sophisticate and improve Wang's attack by using algebraic techniques and introduce new notions, namely semi-neutral bit and adjuster and propose then an improved message modification technique based ongebraic techniques.
Multi-trail Statistical Saturation Attacks
- Computer Science, MathematicsACNS
- 2010
The use of multiple trails is investigated and it is shown that it allows significant improvements of the previous cryptanalysis attempts against PRESENT, and Estimated complexities indicate that PRESENT-80 is safe against key recovery, by a small security margin.

Simplified OAEP for the RSA and Rabin Functions

It is shown that for the Rabin and RSA trapdoor functions a much simpler padding scheme is sufficient for chosen ciphertext security in the random oracle model and that only one round of a Feistel network is sufficient.

We show how to solve a polynomial equation (mod N) of degree k in a single variable x, as long as there is a solution smaller than N1/k. We give two applications to RSA encryption with exponent 3.…

An efficient algorithm that preprocesses the exponentiation of a random residue modulo p is presented, which improves the ElGamal signature scheme in the speed of the procedures for the generation and the verification of signatures and also in the bit length of signatures.
Optimal Asymmetric Encryption-How to Encrypt with RSA
- Computer Science, Mathematics

A slightly enhanced scheme is shown to have the property that the adversary can create ciphertexts only of strings for which the adversary knows the corresponding plaintexts, and is not only semantically secure but also non-malleable and secure against chosen-ciphertext attack.

It is demonstrated that if f is a one-way trapdoor function that is hard to invert, then OAEP combined with f is secure against an INDCCA2 adversary in the random oracle model.

A slightly different proof is exhibited which provides a tighter security reduction of the Full Domain Hash scheme, which improves the efficiency of the scheme since smaller RSA moduli can be used for the same level of security.
