Alice and Bob want to communicate securely over an insecure channel where Evecould be listening. To ensure their message remains confidential, they decide to usea simple substitution cipher for encryption and decryption, where each letter in thealphabet is shifted by a fixed number of places.For this exercise, use a shift of 3 places to the right (a Caesar Cipher). For example,'A' becomes 'D', 'B' becomes 'E', 'Z' becomes 'C', and so on. Spaces and punctuationare not encoded; they remain unchanged.Alice wants to send the following message to Bob: "HELLO WORLD".a. Encrypt Alice's message using the specified shift. Provide the encrypted text.………………………………………………………………………………………………[1]b. Discuss the security of using the Caesar Cipher for encrypting messages.Consider scenarios where Eve knows or does not know the method ofencryption.……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………[1]
