CompTIA Security Plus Mock Test Q1005

Encryption used by RADIUS is BEST described as:

A. Quantum
B. Elliptical curve
C. Asymmetric
D. Symmetric


Correct Answer: D
Section: Cryptography

Explanation:
The RADIUS server uses a symmetric encryption method.
Note: Symmetric algorithms require both ends of an encrypted message to have the same key and processing algorithms. Symmetric algorithms generate a secret key that must be
protected.

Incorrect Answers:
A: Quantum encryption is a hypothetical encryption method not yet in use.
B: Elliptical curve cryptography (ECC) is an approach to public-key cryptography, but the RADIUS protocol uses a private(secret) key.
C: RADIUS uses a symmetric, not an asymmetric, encryption method.
