Question

Project B:-Using Binary Block Ciphers 1. Write a single sentence in normal text. 2. Convert the text to ASCII. There are several Web sites with ASCII code tables, such as http://www.asciitable.com. 3. The convert each character to binary 4. Now create a random 16 bit key. You can literally simply write down a random string of 1s and Os 5.XOR that key with your text. 6. Pass it to another student in class and sive them a chance to decipher it. 7. When you have given all students adequate opportunity to break their fellow students' encryption, have them give each other the appropriate key

Answer 1

Binary Block Cypher

Step 6:

We can create n^{length of plaintext} combination of cipher text.

So here,2⁷⁶ combination.
