Certified Network Defender (CND) — Question 189

The CEO of Max Rager wants to send a confidential message regarding the new formula for its coveted soft drink, SuperMax, to its manufacturer in Texas. However, he fears the message could be altered in transit. How can he prevent this incident from happening and what element of the message ensures the success of this method?

Answer options

• A. Hashing; hash code
• B. Symmetric encryption; secret key
• C. Hashing; public key
• D. Asymmetric encryption; public key

Correct answer: A

Explanation

Hashing is an effective way to ensure message integrity, as it generates a unique hash code that changes if the message is altered. The other options, while related to encryption and security, do not specifically address preventing alterations in transit like hashing does. Symmetric and asymmetric encryption focus on confidentiality rather than integrity.
