==== abstract ====
The filter generator is one of the simplest stream ciphers and, even if it is
 not used directly in practice, the best known attacks against it are still not 
that efficient. One of the main line of attacks tries to exploit the high algebr
aic structure behind this system. We will explain how these algebraic attacks wo
rk and present some new ideas to improve them.
