Often called the Holy Grail of cryptography,
commercial FHE is near.
Mache Creeger, Cornami Inc.
FHE (fully homomorphic encryption) provides quantum-secure computing on encrypted data, guaranteeing that plaintext data and its derivative computational results are never exposed and remain secure from modification and/or breach despite compromised infrastructures. Most FHE schemes are based on lattice mathematics, are believed to be secure from breach by quantum computing,9 and are considered PQC (post-quantum cryptography). New hardware accelerator architectures are an active area of research and development,1,3 and academic research continues to develop new and more efficient implementation schemes, making the full implication of FHE on data processing close to realization.
