Simplified DES: Using S-DES, decrypt the string (10100010) using the key (0111111101) by hand. [20 marks] Show intermediate results after each function (IP, FK,SW,FK,I1), and (K1 and K2) 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,,P=1111 ) Hint: As a midway check, after the application of SW, the string should be (00010011)
