BDD-based Cryptanalysis of Keystream Generators

Many of the keystream generators which are used in practice are LFSR-based in the sense
that they produce the keystream according to a rule $y=C(L(x))$,
where $L(x)$ denotes an internal linear bitstream, produced by a small number of parallel
linear feedback shift registers (LFSRs),
and $C$ denotes ... more >>>
