Mathematically, there is a solution. It’s just really, really slow.


Fully Homomorphic Encryption allows for arithmetic computation *on* encrypted data.


First published in 2009, each individual (x86) operation took 30 minutes! 


AKA, about 10^12 times slower.

Very excited about this ⚡new paper⚡ with Doron and Guy from Fhenix!

We construct very 𝙨𝙞𝙢𝙥𝙡𝙚 and 𝙛𝙖𝙨𝙩 exact fully homomorphic encryption scheme for "high precision" plaintexts, which works for 𝙖𝙣𝙮 plaintext modulus and with 𝙖𝙣𝙮 number/polynomial ring (including ℤ, for a solution from plain LWE).

High-Precision Exact FHE Made Simple, General, and Fast (Chris Peikert, Doron Zarchy, Guy Zyskind) ia.cr/2025/2321
Abstract. Many important applications of fully homomorphic encryption (FHE) require high-precision arithmetic, e.g., plaintext rings ℤ_(p) for a huge prime or power-of-two modulus p. The classic FHE schemes are poorly suited to this, because the inverse error rate of fresh ciphertexts, and the error growth under homomorphic multiplication, are both larger than p, which results in large and inefficient parameters. While there are now several works addressing this problem, the landscape for exact (as opposed to approximate) FHE is highly fragmented: known solutions either work only for certain rare plaintext moduli having very special forms (sometimes using non-standard ciphertext rings that lack other important features for FHE), or have quite complicated and high-latency constructions. This work gives a very simple and general technique for high-precision exact FHE, in which the error rates and growth match those of prior schemes with exponentially smaller precision, and which has good practical efficiency. In contrast to all prior works, our scheme works for any integer modulus, and also over any underlying (number) ring—or even with no structured ring at all, making it the first solution that can be based on plain LWE. It is also fully compatible with prior FHE techniques for fast ring arithmetic, plaintext packing and SIMD operations, bootstrapping, etc. For plaintext ring ℤ_(2⁶⁴), our (preliminary, unoptimized, single-threaded) implementation does homomorphic multiplication in just tens of milliseconds, and supports a two- to three-fold increase in multiplicative depth versus classic FHE schemes at typical security levels.

Thrilled to finally share this ⚡𝙣𝙚𝙬 𝙥𝙖𝙥𝙚𝙧⚡ with my (now-graduated!) student Zachary Pepin, which will appear at TCC 2025.

We tackle a frequent inconvenience in BGV/BFV-style homomorphic encryption: getting the desired kind of "SIMD slots" for plaintext packing. 🧵

Screenshot of the title and abstract of the paper "Vive Galois! Part 1: Optimal SIMD Packing and Packed Bootstrapping for FHE", by Chris Peikert and Zachary Pepin. Abridged abstract: The vast majority of work on the efficiency of lattice-based cryptography, including fully homomorphic encryption (FHE), has relied on cyclotomic number fields and rings. This is because cyclotomics offer a wide variety of benefits, including good geometrical properties, fast ring arithmetic, and rich homomorphic operations like vectorized (SIMD) operations on "packed" plaintexts, automorphisms, and ring-switching. However, selecting a suitable cyclotomic that has the desired number and type of plaintext "slots," while also balancing security and efficiency, is a highly constrained problem that often lacks an ideal solution, resulting in wasted SIMD capacity and lost efficiency. This work provides a suite of tools for instantiating ring-based lattice cryptography to work over *subfields* of cyclotomics, which provide more flexibility and better-fitting parameters for applications. A particular focus is on realizing FHE with *optimal plaintext packing* and homomorphic SIMD parallelism for *any* plaintext characteristic, along with efficient packed bootstrapping that fully exploits this parallelism.
