B)Nonrepudiation
C)Integrity
D)Confidentiality

Question

Quizplus · Accepted Answer

The use of MD5 hashing algorithm allows Bob to verify the integrity of the message sent by Alice. Since the hash value generated by Bob matches with the one sent by Alice, it means that the message has not been tampered with during transmission. However, authentication involves verifying the identity of the sender, non-repudiation involves ensuring that the sender cannot deny sending the message, and confidentiality involves securing the message content from unauthorized access.
