Does the Caesar Clpher use the symmetric encryption model, or the asymmetric encryption model? Explain your answer. 4. If you intercepted a message that had been encrypted using a Caesar Clpher, what is the maximum number of times you would need to guess-and-check different keys for the cipher before cracking it?

1. Some advantages of using a Caesar Cipher include its simplicity and ease of implementation. It is also relatively fast to encrypt and decrypt messages using this method.<br />2. Some disadvantages of using a Caesar Cipher include its vulnerability to frequency analysis attacks, as it only shifts the letters in the alphabet by a fixed number of positions. This makes it easy for attackers to guess the key and decode the message. Additionally, it is not suitable for secure communication as it can be easily broken by brute force attacks.<br />3. The Caesar Cipher uses the symmetric encryption model. In symmetric encryption, the same key is used for both encryption and decryption. This means that both the sender and the receiver must know and use the same secret key to encrypt and decrypt the message.<br />4. If you intercepted a message that had been encrypted using a Caesar Cipher, the maximum number of times you would need to guess-and-check different keys for the cipher before cracking it would be 25. This is because there are 26 possible keys in the English alphabet, and the Caesar Cipher shifts the letters by a fixed number of positions. Therefore, you would need to try all 26 possible keys to find the correct one.
