CDPSE Privacy Engineering Practice Question
You are integrating a homomorphic encryption library into a cloud-based financial system. What is the primary trade-off you must communicate to stakeholders regarding the implementation of Fully Homomorphic Encryption (FHE)?
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
✓
Significant latency during computation
FHE is computationally expensive, leading to significant latency increases for complex analytical operations on encrypted data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Incompatibility with cloud storage
Why it's wrong here
FHE is designed specifically for cloud processing of sensitive data.
- ✗
Increased storage requirements
Why it's wrong here
While some ciphertext expansion occurs, the main issue is processing speed, not storage.
- ✗
Loss of data integrity
Why it's wrong here
Homomorphic encryption preserves the structure and integrity of the underlying data.
- ✓
Significant latency during computation
Why this is correct
FHE operations require massive computational overhead, causing slow query performance.
