ITPEC IP April 2026 Question 38
ITPEC IP April 2026 — Question 38 of 100
One-time password — a token generates a different authentication value for each use or short time period.
Because the code changes, a captured old code cannot normally be replayed later. Hardware tokens and authenticator applications commonly generate time-based or counter-based one-time passwords.
Answer (d)
Why not others: (a) signs data to prove origin and integrity; (b) is an attack that discovers passwords; (c) is a set of rules about password creation and handling, not a changing token value.
Key rule: A token plus a changing code indicates OTP; the short validity reduces replay risk.
