6. (10 pts) To send some data to a server, Alice needs to first ask a certificate authority

about the server's public key. However, Alice knows only one certificate authority, say

CA, and she does not know CA's public key. Alice decides to ask CA about CA's public

key.

(a) (2 pts) Is this possible if the communication channel between Alice and CA is

secure?

(b) (8 pts) Mallory is a man-in-the-middle. What can Mallory do to steal Alice's data?

7. (10 pts) Alice is using an insecure PRNG which allows an attacker to predict the next
