Bob wants to send Alice the message, "JAW," which he plans to encrypt using Alice's RSA cypher with public key (pq, e) = (55, 3). To encrypt the message, Bob uses the method described in Example 8.4.9. He encodes one letter at a time using A = 01, 8 = 02, C = 03,..., Z = 26. Next, he applies the encrypting formula C = MⓇ mod pq, where M is a plaintext letter and C is a block f ciphertext. Because 55 is a two-digit integer, each block of ciphertext is a two-digit integer with 0, 1, 2..., 9 represented as 01, 02, 03,..., 09. (Enter your answers using a fixed number of digits: 01 for 1, 02 for 2,..., 09 for 9, 10, 11, etc.) 3 mod 55 = (a) When the first letter of the message is encoded, the result is Bob then applies the encrypting formula find that the first two-digit block of the encrypted message is 3 mod 55 = (b) The second two-digit block of Bob's encrypted message is [ (c) What is the fully encrypted message that Alice receives? (Enter the message as a sequence of integer doubles separated by a single space, where each double is written using a fixed number of digits: 01 for 1, 02 for 2,...,09 for 9, 10, 11, etc.)
