Fast correlation attacks on the multiplexer generator
Leonie Ruth Simpson, Ed Dawson, Jovan Dj. Golić, Mahmoud Salmasizadeh · 2002
The fast correlation attack based on iterative probabilistic decoding is applied to multiplexer generators. The attack is successful if the number of parity-checks used is large given the coefficient of correlation between the keystream sequence and phase-shifts of an underlying shift register sequence.
