Question: 3. Consider a block cipher where the block length is 3 and each block of length 3 is encrypted using bitwise XOR with a key

3. Consider a block cipher where the block length is 3 and each block of length 3 is encrypted using bitwise XOR with a key K of length 3. (b) Assume that K = 101. What is the encryption of 000111110? (10 marks) Assume that the plaintext is 111101 and the resulting encryption is 011001. What is K? (10 marks)
