Assume that you are an attacker and you know that the system is using a stream cipher with an LFSR of degree m=3 to generate the random number. You would like to break this cipher and find out the values of X6 and X7 in the plaintext Use the information provided to you in the figure below to break this stream cipher and to find out the values of X6 and X7. Please show all of your work. I know all the ciphertext S1, S2, S3 ... You 01100101 001110 x6 X
