Question: Write a program in MATLAB or C/C++ that can encrypt and decrypt using S-DES (simplified DES).
Test data: Use plaintext, ciphertext and the key of substance 3.18. Put comments on your program script and transmit me a zip rasp delay all of the program rasps and your results (output shade stop) pages, delay your spectry as the rasp spectry.
3.18 Using S-DES, decrypt the string (10100010) using the key (0111111101) by operative.
Show intervening results thriveing each power (IP, Fk, SW, Fk, IP-1). Then decode the
first 4 bits of the plaintext string to a epistle and the cooperate 4 bits to another epistle
where we encode A through P in mean 2 (i.e., A = 0000, B = 0001,..., P = 1111).
Modify your S-DES program which you created latest week to effect in triple-S-DES code. Submit your software and imimprint out of your output shade.
Please thrive the incorporate beneath to set-on-foot your AES lab assignment. The lab narration is due by Sunday.
