A New Attack on the LEX Stream Cipher
Abstract. In [6], Biryukov presented a new methodology of stream cipher design, called leak extraction. The stream cipher LEX, based on this methodology and on the AES block cipher...

Distinguishing Attacks on the Stream Cipher Py
The stream cipher Py designed by Biham and Seberry is a submission to the ECRYPT stream cipher competition. The cipher is based on two large arrays (one is 256 bytes and the other ...

Improved Linear Distinguishers for SNOW 2.0
In this paper we present new and more accurate estimates of the biases of the linear approximation of the FSM of the stream cipher SNOW 2.0. Based on improved bias estimates we als...

Vulnerability of Nonlinear Filter Generators Based on Linear Finite State Machines
We present a realization of an LFSM that utilizes an LFSR. This is based on a well-known fact from linear algebra. This structure is used to show that a previous attempt at using a...

On the (Im)Possibility of Practical and Secure Nonlinear Filters and Combiners
A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...
