Certified Cloud Security Professional (CCSP) — Question 438

What is the experimental technology that might lead to the possibility of processing encrypted data without having to decrypt it first?

Answer options

• A. One-time pads
• B. Link encryption
• C. Homomorphic encryption
• D. AES

Correct answer: C

Explanation

Homomorphic encryption allows computations to be performed on ciphertexts, producing an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. One-time pads and link encryption do not offer this capability, while AES is a symmetric encryption standard that requires decryption for processing.
