Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

2. Defined in RFC 2289 - a mechanism by which a shared key and a secret key together feed into a hash algorithm - creating a password that is transmitted over a network. Because the shared key is not reused - the hash value is only valid for that indivi
