2Fully homomorphic encryption and the dawn of a private internet
- This article explores Fully Homomorphic Encryption (FHE), a technology that enables computations on encrypted data without decryption. While currently impractical due to performance overhead, FHE is improving rapidly, becoming 8x faster annually. If this trend continues, it could revolutionize cloud computing, AI inference, and blockchain smart contracts, potentially transforming internet privacy from "spy by default" to "privacy by default."
Fundamental limitations of FHE
FHE has 1000x+ overhead due to bootstrapping, making it impractical for most uses. Speed improvements unlikely to close gap. Database search becomes O(n) vs O(log n). Ciphertext size 1000x larger than plaintext.Market viability concerns
Discussion of whether users would pay 1000x more for privacy. Most argue market too small except specialized cases. Self-hosting seen as better alternative. Companies have little incentive to implement FHE.Confidential computing alternatives
Debate around using hardware-based confidential VMs and trusted execution environments (TEE) as more practical privacy solution vs FHE. Some question security but seen as part of layered defense.
