Fully Homomorphic Encryption

The Holy Grail of Confidentiality

Fully Homomorphic encryption (FHE) is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. In simpler terms, it enables data to be manipulated and processed in its encrypted form, maintaining its confidentiality throughout the entire computation process.

FHE operates using mathematical concepts from algebraic geometry, number theory, and lattice-based cryptography. The basic idea behind FHE is to use mathematical structures that allow operations to be performed on encrypted data in a way that, when decrypted, produce the same result as if the operations were performed on the original unencrypted data.
