CCSP Question #784: Real Exam Question with Answer & Explanation
The correct answer is D: Homomorphic encryption. Homomorphic encryption allows computations to be performed directly on ciphertext, producing an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. This means data can remain encrypted during processing - a major privacy breakthroug
Question
What is the experimental technology that might lead to the possibility of processing encrypted data without having to decrypt it first?
Options
- AAES
- BLink encryption
- COne-time pads
- DHomomorphic encryption
Explanation
Homomorphic encryption allows computations to be performed directly on ciphertext, producing an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. This means data can remain encrypted during processing - a major privacy breakthrough still largely experimental. AES is a symmetric encryption standard, link encryption protects data in transit between nodes, and one-time pads are theoretically unbreakable but impractical, none of which allow computation on encrypted data.
