Question: We 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

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

We 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 (a) What is the degree m of the stream generator? (b) What is the initialization vector? (c) Determine the feedback coefficients of the LFSR. (d) Draw a circuit diagram and verify the output sequence of the LFSR
