Hi,

Could you please help me solving one problem from homework? The following cipher text was obtained by adding (mod 2) as the output of a LFSR:

0110101010011000101010101010100100010110

You know that the plaintext starts as follows:

11111100000011100

(a) Determine the length of the recurrence by the method described in class.

(b) Find the coefficients of the recurrence.

(c) Find the entire plaintext..

I have no idea how to solve this and I have an exam. I would more than appreciate any help.

Yours Sincerely,

_Teona
