Encryption used by CRC data handling primarily protects which aspects of data?

• A. Confidentiality and integrity
• B. Availability
• C. Non-repudiation
• D. Auditability

Answer: (A)

Encryption primarily protects confidentiality—the data becomes unreadable to anyone without the key. When you encrypt, you guard the content from unauthorized access during storage or transit. If encryption is used in an authenticated form (or paired with a message authentication code), you also gain data integrity, because any tampering would be detected during decryption. So, for CRC data handling, confidentiality is the main benefit, and integrity can be provided as well when authentication is included. The other aspects—availability, non-repudiation, and auditability—are not the primary goals of encryption.
