In this answers we will discuss about initialization vector used and below are the summaries point:-
The initialization vector used in the stream cipher is determined by a matrix calculation and recurrence relation.
The feedback coefficients of the linear feedback shift register (LFSR) are determined using the Berlekamp-Massey algorithm.
The LFSR diagram and its parallel formulas are provided to illustrate the implementation of the given stream cipher.
