CCSP Cloud Data Security Practice Question
An organization is required to use client-side encryption for all data uploaded to a cloud storage service to ensure that the cloud provider has no access to plaintext. However, they also need to allow the cloud provider to perform server-side operations like indexing and search on the encrypted data. Which technology can address this conflict?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Searchable encryption
Searchable encryption allows certain operations (e.g., keyword search) on encrypted data without decrypting it, enabling server-side processing while maintaining confidentiality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Format-preserving encryption
Why it's wrong here
FPE preserves format but does not enable server-side operations.
- ✓
Searchable encryption
Why this is correct
Correct: Searchable encryption enables server-side search on encrypted data.
- ✗
Tokenization
Why it's wrong here
Tokenization replaces data with tokens, but server cannot perform meaningful operations on tokens.
- ✗
Homomorphic encryption
Why it's wrong here
Homomorphic encryption allows computations on ciphertext, but is not widely practical for indexing.
