Question:
Using S-DES, convert the string of bits obtained from your roll no (89) ( e.g. roll no 12 can be represented as 0001 0010) using the key 1111 1111 by hand to encrypted bits. 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).
