ITPEC IP April 2021 Question 40
ITPEC IP April 2021 — Question 40 of 100
A token that generates different authentication information for each use provides a one-time password. The code is valid for only one login or a short time interval, so a captured old value cannot normally be reused in a later replay attempt.
Answer (d)
Why not others:
- a digital signature proves origin and integrity with public-key cryptography
- password cracking is an attack that attempts to discover a password
- a password policy defines rules for password creation and management
Key rule: An OTP is a changing, single-use or time-limited secret generated independently for each authentication.
