An administrator has two servers and wants them to communicate with each other using a secure algorithm.
Which of the following choose to provide both CRC integrity checks and RCA encryption?
A.
NTLM
B.
RSA
C.
CHAP
D.
ECDHE
Explanation:
ECDHE provides both CRC integrity checks and RCA encryption.
Adding an ephemeral key to Elliptic Curve Diffie-Hellman turns it into ECDHE. It is the ephemeral component of
each of these that provides the perfect forward secrecy.
Forward secrecy is a property of any key exchange system, which ensures that if one key is compromised,
subsequent keys will not also be compromised. Perfect forward secrecy occurs when this process is
unbreakable.
