Question

Let M be the plaintext message M = MALAYSIA and the private key, K = ISSOGOOD

Using the appropriate steps of DES operation, get the final output of the key for round 1 with the permutation compression (PC) table provided below, For round 1, get the output for the XOR operation of plaintext and the key, according to the DES operation.

Based on the output above, explain the next process using the S-box table, and show the output from this operation.
Based on the output of of 4(a), explain the next process using a straight permutation table, and show the output from this operation.
