I 10 pts ] Consider the two S-boxes S1 and S2 of DES shown. Three hex digits (12 bits) are provided to these two S boxes. The higher order six bits are fed to S1 and the lower order six bits are fed to S2. For the six bits input to S1, the first and last bits are used to select the row, and the middle four bits are used to select the column. Note that each S box has four rows numbered 0, 1, 2, and 3 and sixteen columns numbered 0 to 15. So, two bits are sufficient to select a row, as 22 4 and four bits are sufficient to select a column, as 24 16. The output from each S box is a four bit binary number, which means that the output from each S box ranges from O to 15. You must express the output of the S-boxes in hexadecimal, even though the table values are in decimal SI CO C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 13 14 15 RO 0 15 7 4 14 2 13 1 10 6 12 11 9 5 3 8 R1 4 1 14 8 13 6 2 11 15 12 9 7 3 10 5 0 R2 14 4 13 1 2 15 11 8 3 10 6 12 5 9 0 7 R3 15 12 8 249 1 7 5 11 3 14 10 0 6 13 S2 CO C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 RO 15 1 8 14 6 11 3 4 9 7 2 13 12 0 5 10 R1 13 8 10 1 3 15 4 2 11 6 7 12 0 5 14 9 R2 3 13 4 7 15 2 8 14 12 0 1 10 6 9 11 5 R3 0 14 7 11 10 4 13 1 5 8 12 6 9 3 2 15 Determine the hexadecimal output for the following input: AF716 AF716 input to S1- 2 So, the row selector row no. 10 And the column selector - column no....10 Thus, the output from S1-6 input to S2 = So, the row selector row no. 10 And the column selector = column no 10 Output from S216 Hence, the output is-16
