This question uses the alphabet encoding A=0, B=1, C=2, ... Y=24, Z=25. In the first line of the solution box below, write your username with uppercase letters. Using the alphabet encoding above, encrypt the first three letters of the UPI using the block cipher encryption matrix: [16 4 11 K 3 6 0 L10 3 2 = using modulo-26 arithmetic. Write the THREE LETTERS of ciphertext into the second line of the solution box below. (Do not encrypt the rest of your UPI) Answer: (penalty regime: 0 %) 1 Precheck Check This question uses the alphabet encoding A=0, B=1, C=2, ... Y=24, Z=25.
