Certified Data Privacy Solutions Engineer (CDPSE) — Question 118

What should a sender do to send a recipient a file of personal data using asymmetric encryption?

Answer options

• A. Recipient's private key is used to encrypt; recipient's public key is used to decrypt.
• B. Sender’s public key is used to encrypt; recipient's public key is used to decrypt.
• C. Recipient's public key is used to encrypt; recipient's private key is used to decrypt.
• D. Recipient's private key is used to encrypt; sender’s public key is used to decrypt.

Correct answer: C

Explanation

The correct answer is C because asymmetric encryption requires the sender to encrypt data with the recipient's public key to ensure only the recipient can decrypt it using their private key. Options A, B, and D incorrectly describe the roles of public and private keys in the encryption and decryption process.
