CCSP Question #809: Real Exam Question with Answer & Explanation
The correct answer is C: Homomorphic encryption. Homomorphic encryption is a form of encryption that allows computations to be performed directly on ciphertext, producing an encrypted result that, when decrypted, matches the result of the same operations performed on the plaintext. This eliminates the need to decrypt data befor
Question
What is the experimental technology that might lead to the possibility of processing encrypted data without having to decrypt it first?
Options
- AOne-time pads
- BLink encryption
- CHomomorphic encryption
- DAES
Explanation
Homomorphic encryption is a form of encryption that allows computations to be performed directly on ciphertext, producing an encrypted result that, when decrypted, matches the result of the same operations performed on the plaintext. This eliminates the need to decrypt data before processing it, which is highly valuable for privacy-preserving cloud computing. It remains largely experimental and computationally expensive for general use. One-time pads are perfectly secure classical encryption, link encryption protects data in transit, and AES is a widely used symmetric block cipher - none of these enable computation on encrypted data.
