S boxes for DES are provided below
Implement a single round of DES in C(++) or Java. The steps were explained in class. It does not need to include the initial or final permutation. Test with the round keys 0x123456789abc for DES. Measure the execution speed of the implementation (using the time service). (You may need to execute the function more than once to get meaningful results.) The S boxes for DES are provided in the KPS textbook or S1 14, 4, 13, 1, 2, 15, 11, 8,3, 10, 6, 12, 5, 9, 0, 7, e, 15, 7, 4, 14, 2, 13, 1, 10, 6, 12, 11, 9, 5, 3, 8, 4, 1, 14, 8, 13, 6, 2, 11, 15, 12, 9, 7, 3, 1e, 5, e, 15, 12, 8, 2, 4, 9, 1, 7, 5, 11, 3, 14, 1e, e, 6, 13, S2 15, 1, 8, 14, 6, 11, 3, 4, 9, 7, 2, 13, 12, e, 5, 10, 3, 13, 4, 7, 15, 2, 8, 14, 12, e, 1, 10, 6, 9, 11,5, 0, 14, 7, 11, 1e, 4, 13, 1, 5, 8, 12, 6, 9, 3, 2, 15, 13, 8, 10, 1, 3, 15, 4, 2, 11, 6, 7, 12, 0, 5, 14, 9, S3 1e, e, 9, 14, 6, 3, 15, 5, 1, 13, 12, 7, 11, 4, 2, 8, 13, 7, e, 9, 3, 4, 6, 16,2, 8, 5, 14, 12, 11, 15, 1, 13, 6, 4, 9, 8, 15, 3, e, 11, 1, 2, 12, 5, 1e, 14, 7, 1, 1e, 13, , 6, 9, 8, 7, 4, 15, 14, 3, 11, 5, 2, 12, S4 7, 13, 14, 3, e, 6, 9, 1, 1, 2, 8, 5, 11, 12, 4, 15, 13, 8, 11, 5, 6, 15, e, 3, 4, 7, 2, 12, 1, 1e, 14, 9, 10, 6, 9, e, 12, 11, 7, 13, 15, 1, 3, 14, 5, 2, 8, 4, 3, 15, e, 6, 1e, 1, 13, 8, 9, 4, 5, 11, 12, 7, 2, 14, S5 2, 12, 4, 1, 7, 1e, 11, 6, 8, 5, 3, 15, 13, e, 14, 9, 14, 11, 2, 12, 4, 7, 13, 1, 5, e, 15, 10, 3, 9, 8, 6, 4, 2, 1, 11, 10, 13, 7, 8, 15, 9, 12, 5, 6, 3, , 14, 11, 8, 12, 7, 1, 14, 2, 13, 6, 15, e, 9, 10, 4, 5, 3, S6 12, 1, 1e, 15, 9, 2, 6, 8, e, 13, 3, 4, 14, 7, 5, 11, 1e, 15, 4, 2, 7, 12, 9, 5, 6, 1, 13, 14, e, 11, 3, 8, 9, 14, 15, 5, 2, 8, 12, 3, 7, e, 4, 10, 1, 13, 11, 6, 4, 3, 2, 12, 9, 5, 15, 10, 11, 14, 1, 7, 6, e, 8, 13, S7 4, 11, 2, 14, 15, e, 8, 13, 3, 12, 9, 7, 5, 1e, 6, 1, 13, 0, 11, 7, 4, 9, 1, 18, 14, 3, 5, 12, 2, 15, 8, 6, 1, 4, 11, 13, 12, 3, 7, 14, 1e, 15, 6, 8, e, 5, 9, 2, 6, 11, 13, 8, 1, 4, 1e, 7, 9, 5, e, 15, 14, 2, 3, 12, S8 13, 2, 8, 4, 6, 15, 11, 1, 1e, 9, 3, 14, 5, e, 12, 7, 1, 15, 13, 8, 10, 3, 7, 4, 12, 5, 6, 11, e, 14, 9, 2 7, 11, 4, 1, 9, 12, 14, 2, e, 6, 1, 13, 15, 3, 5, 8, 2, 1, 14, 7, 4, 10, 8, 13, 15, 12, 9, e, 3, 5, 6, 11 Implement a single round of DES in C(++) or Java.
