Question 11 (1 point)

Approximately how many different starting settings could be created from the Enigma machine's remarkably simple architecture.

Question 11 options:

	160 X 10 ^9
	160 X 10^36
	160 X 10^72
	160 X 10^18 Question 12 (1 point) PGP uses a two-phase encryption approach to encrypt a message, and a second two-phase approach to decrypt a message. Alice wishes to send a message to Bob that will be confidential and also prove to Bob that Alice was the sender. Which of the following pairs of phases is the correct sequence of phases that will accomplish Alice's objectives. Pair 1: To encrypt the message, Alice uses Alice's private key, then Bob's public key, and sends the message to Bob. Pair 2: To encrypt the message, Alice uses Bob's public key, then Alice's private key, and sends the message to Bob. Pair 3: To decrypt the message, Bob uses Bob's private key, then Alice's public key. Pair 4: To decrypt the message, Bob uses Bob's public key, then Bob uses Alice's public key. Question 12 options: Pairs 1 and 4 None of the choices is correct Pairs 1 and 3 Pairs 2 and 3 Pairs 2 and 4 Question 13 (1 point) Alice sends Bob an encrypted message using the RSA encryption method. The RSA encryption method is based on two functions. Given P = plaintext, and C = ciphertext, the two functions are: P = C ^ G (mod N) C = P ^ H (mod N) What is G? Question 13 options: Alice's public key Alice's private key Bob's private key Bob's public key Question 14 (1 point) Alice sends Bob an encrypted message using the RSA encryption method. The RSA encryption method is based on two functions. Given P = plaintext, and C = ciphertext, the two functions are: P = C ^ G (mod N) C = P ^ H (mod N) What is H? Question 14 options: Alice's public key Bob's private key Bob's public key Alice's private key Question 15 (1 point) In the context of Information Assurance and Security, the HIPAA Security Rule requires that individually identifiable patient information must be protected.
