Answer completely and carefully based on cryptography for thumbs up.

Bob wishes to receive a message from Alice which has been authenticated via a digital signature RSA system. (b) Bob receives x = 82 and y = xd = 27 as the RSA signature. From the perspective of Bob, who has modulus n = 115 and public key e = 9, but does not know Alice's private key, verify via square and multiply, that Alice's signature is correct. Show all steps
