Which technique encrypts data in use, enabling computation on encrypted data without decryption?
- Homomorphic Encryption
- Format-Preserving Encryption
- Tokenization
- Data Masking
Answer: Homomorphic Encryption
Homomorphic Encryption allows computations on ciphertext, producing encrypted results that decrypt to correct output. Enables privacy-preserving cloud analytics, secure voting, and confidential AI. Still computationally intensive but advancing with research. Critical for privacy-enhancing technologies.
