Conduct a known-plain text attack on an LFSR-based stream cipher.

We know that the plain text sent was:1001 0010 0110 1101 1001 0010 0110

By tapping the channel we observe the following stream: 1011 1100 0011 0001 0010 1011 0001

Question 1) What is the degree m of the key stream generator?

Question 2) What is the initial state?

Question 3) Determine the feedback coefficients of the LFSR.

Question 4) Draw a circuit diagram and verify the output sequence of the LFSR.
