(b) Messages are to be encoded using the RSA method, and the primes chosen are p - 11 and q - 19, so that n pq - 209. The encryption exponent is e 17. Thus, the public key is (209, 17). (1) Show that the decryption exponent d (the private key) is 53. (ii) Use the repeated squaring algorithm to find the encrypted form c of the message m - 47.
