Bob wants to send Alice the message, FuN, which he plans to encrypt using Alice's RSA cypher with public key ( pq , e )
Bob wants to send Alice the message, "FuN," which he plans to encrypt using Alice's RSA cypher with public key pq e To encrypt the message, Bob uses the method described in Example He encodes one letter at a time using dots, Next, he applies the encrypting formula
modpq,
where is a plaintext letter and is a block of ciphertext. Because is a twodigit integer, each block of ciphertext is a twodigit integer with represented as dots,Enter your answers using a fixed number of digits: for for dots, for etc.
a When the first letter of the message is encoded, the result is of the encrypted message is mod Bob then applies the encrypting formula to find that the first twodigit block
mod
b The second twodigit block of Bob's encrypted message is mod
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: for for dots, for etc.
