![SOLVED: We conduct a known-plaintext attack on an LFSR-based stream cipher. We know that the plaintext sent was: 1001001001101101100100100110. By tapping the channel carrying the ciphertext, we observe the following stream: 10111100001100001001010110001. SOLVED: We conduct a known-plaintext attack on an LFSR-based stream cipher.
