Which type of password provides maximum security because a new password is required for each
now log-on is defined to as?

A.
One-time or dynamic password

B.
Cognitive password

C.
Static password

D.
Pass phrase

Explanation:
“One-time” or “dynamic” password technology concept is having your remote host
already know a password that is not going to go over insecure channels and when you connect,
you get a challenge. You take the challenge information and password and plug it into an
algorithm which generates the response that should get the same answer if the password is the
same on the both sides. Therefore the password never goes over the network, nor is the same
challenge used twice. Unlike SecurID or SNK, with S/key you do not share a secret with the host.
Other one time password technology is card systems where each user gets a card that generates
numbers that allow access to their account. Without the card, it is improbable to guess the
numbers.
