2. Use the following permutation box to encrypt the last two digits of your Banner ID (adding 2 to each digit first): 3 6 1 Specifically: 2 8 | 5 4 a) Add 2 to each of your last 2 digits and then compute the 4 bit binary numbers for those values. For example, if the last two digits were 94, this would be 11 and 6, which would be 1011 0110 in binary. b) Run the resulting 8 bit binary number through the above permutation box.
