### Paper: Decimation Attack of Stream Ciphers

Authors: Eric FILIOL URL: http://eprint.iacr.org/2000/040 Search ePrint Search Google This paper presents a new attack called {\em Decimation Attack} of most stream ciphers. It exploits the property that multiple clocking (or equivalently $d$-th decimation) of a LFSR can simulate the behavior of many other LFSRs of possible shorter length. It yields then significqnt improvements of all the previous known correlation and fast correlation attacks provided a new criterion is satisfied. This criterion on the length of the feedback polynomial is then defined to resist the decimation attack. Simulation results and complexity comparison are detailed for ciphertext only attack.
