Group of answer choices Ciphertext Shared secret Private key Public keyInstructions: 1. Read: Computer Security Fundamentals, 4th edition (Chapter Eight) 2. Answer: Answer the following questions: • Question 1: It is easy to use encryption to hide messages inside of other objects. Steganography is the art of hidden writing. You can get Hide In Picture (HIP) at https://hide-in-picture.soft112.com/.. You can then encrypt a message or even a program that can be extracted by using an encryption key. Download HIP, hide a text message in a picture, and send the picture and key to your classmate to see whether he can extract the secret message. How could you detect hidden messages in web page images? Individual Assignment 2 • Question 2: ROT13 is an interesting encryption algorithm in that it has no key. It uses a form of the Caesar cipher to encrypt text. Try encoding a message by entering text in the box at http://www.rot13.com/. Exchange your encrypted message with someone else in class. Then enter their coded message you've received into the text box.…You encrypt the message zzzzzzzzzz (there are 10 z's) using the following cryptosystem: Vigenère cipher with key length 7. Eve intercepts the ciphertext. She knows the encryption method (including key size) and knows what your plaintext is. For the cryptosystem, determine whether or not Eve can use this information to determine the key. Explain your answer.
