In this assignment, you are asked to perform data encryption using the Simplified Data Encryption Standard $($S$-$DES$)$ manually. $($Note: each student will use a different plain text and key$).$

Step $1.$ Find out the data you need to work on

Use the last $3$ digits of your student ID to identify the row that contains $10-$bit key, and plain text you need. Determine all intermediate answers and find out the ciphertext.
