I encrypt the message and send you the encrypted message. Along with it, I give you instructions on how to decrypt it I encrypted it with a ROT-X cipher A ROT-X cipher is just a cipher that replaces each letter in the message with the letter that is X places afterwards For example, in a ROT-1 cipher, the letter A is replaced with B B is replaced with C. If you come to the end of the alphabet, then wrap around. Therefore, Z becomes A As an example, the ROT-1 cipher of HELLO IS IFMMP. To decrypt, just go backwards. For example, if you are working with a ROT-1 cipher, B goes back to A C goes back to B. If you are working with a ROT-1 cipher and you are given the message HPPECZF, you would work back. The decryption of this is GOODBYE. To find X Multiply my public key q with your private key p. The message is as follows vG TIGQKY 1. What is the message? [6] 2. If someone intercepts the message and reads it why won't they be able to decrypt it? [4] 3. What happens if they try to use their own private key? [4] 4 A public key is a key that is known publicly. Therefore, the interceptor would know this key. What is preventing them from changing the message? [6]
