FHE

Encryption

Data Encryption at Rest Secure Multi‑Party Computation Homomorphic Encryption Fully Homomorphic Encryption (FHE)

Abbreviation for Fully Homomorphic Encryption; enables computation directly on ciphertexts.

Definition

FHE is fully homomorphic encryption, a cryptographic scheme that supports arbitrary computation on ciphertexts, producing an encrypted output that decrypts to the correct result.

In plain English Abbreviation for Fully Homomorphic Encryption; enables computation directly on ciphertexts.

Why this matters

Why it matters: It can enable privacy-preserving analytics and cloud computation with reduced plaintext exposure, though performance costs can be high.

Example

Example: A cloud runs a model on encrypted inputs and returns an encrypted prediction to the client for decryption.
