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.
