Question: Suppose that as part of Bob's early (unsuccessful) experiment with cloud based surveys, the authentication system allows the user to attempt 100 passwords per second, but the user must wait for a 5 second lockout period, every 10 seconds. The password Bob used is 5 digits in length, only digits 0 - 9 inclusive allowed.

a) Showing all steps, Calculate and show the total amount of time required for the attacker to guarantee to guess the password, including delays and actual guessing time.

b) Bob eventually adjusted his authentication system to make it more difficult using hashing and other techniques, but then he realized that Malice has been capturing the hashed passwords sent from his laptop to the cloud server for authentication, to try to replay the hashes.

List the basic attack vectors Bob's latest authentication system is vulnerable to, based on the description in B). Then, briefly explain how you would improve the system
