Sammanfattning
The F-FCSR stream cipher family has been presented a few years ago.
Apart from some flaws in the initial propositions, corrected
in a later stage, there are no known weaknesses of the core of these
algorithms. The hardware oriented version, called FCSR-H, is one of
the ciphers selected for the eSTREAM portfolio.
In this paper we present a new and severe cryptanalytic attack on the
F-FCSR stream cipher family. We give the details of the attack when
applied on F-FCSR-H. The attack requires a few Mbytes of received
sequence and the complexity is low enough to allow the attack to be
performed on a single PC within seconds.
