Using S-DES, decrypt the string 01000110 using the key 1010000010 by hand. Show intermediate results after each function (IP, FK, SW, FK, IP-1 ). Then decode the first 4 bits of the plaintext string to a letter and the second 4 bits to another letter where we encode A through P in base 2 (i.e., A = 0000, B = 0001, c, P = 1111). Hint: As a midway check, after the xoring with K2, the string should be 11000001.
