New Weaknesses in the Keystream Generation Algorithms of the Stream Ciphers TPy and Py
The stream ciphers Py, Py6 designed by Biham and Seberry were promising candidates in the ECRYPT-eSTREAM project because of their impressive speed. Since their publication in Apri...

Cryptanalysis of an E0-like Combiner with Memory
In this paper, we study an E0-like combiner with memory as the keystream generator. First, we formulate a systematic and simple method to compute correlations of the FSM output seq...

Some Attacks on the Bit-Search Generator
The bit-search generator (BSG) was proposed in 2004 and can be seen as a variant of the shrinking and self-shrinking generators. It has the advantage that it works at rate 1/3 usin...

The Conditional Correlation Attack: A Practical Attack on Bluetooth Encryption
Motivated by the security of the nonlinear filter generator, the concept of correlation was previously extended to the conditional correlation, that studied the linear correlation...
