Weekly CISSP Exam Questions

In SSL/TLS, what ensures the integrity of the message?

A.  Digital Certificate

B.  Symmetric Encryption

C.  Hash Function

D.  Asymmetric Encryption

 

Correct Answer: C

Explanation:

Digital Certificate: Digital certificates are used to verify the identity of the parties involved in the communication, but they do not ensure the integrity of the message itself.

Symmetric Encryption: Symmetric encryption is used for confidentiality, ensuring that the message can't be understood if intercepted. However, it does not ensure that the message has not been altered.

Hash Function: Hash functions are used to ensure the integrity of the message. They provide a way to detect if the message has been altered during transit.

Asymmetric Encryption: This type of encryption is used for securing the initial key exchange and can be used for ensuring confidentiality but doesn't, by itself, ensure message integrity.
