Data security creates a paradox.
The most valuable data is the data that can’t be shared.
Fully homomorphic encryption solves this problem by allowing truly blind computation.
Fully homomorphic encryption belongs to a class of problems that cannot be solved efficiently using standard Von Neumann architectures.
We combine optical device physics with bespoke supporting electronics to create the ultimate FHE accelerator.
FHE contains a range of implementations that cover different data applications. However, all of these methods work on the same fundamental principles.
Optalysys Etile is a hybrid photonic-electronic chiplet designed around the properties of optical processing.
Pairing digital interfaces with silicon photonics technology, Etile integrates with conventional digital electronics in multi-chip modules, bringing the huge advantages of optical processing to where they are needed in the most intensive compute tasks.
Combined digital-photonic infrastructure on a single die. Optical modulators and detectors convert information to and from the processing environment.
Designed for digital integration. High performance chip interfaces allows Etile to work with existing multi-chip-module technology.
Highly scalable. Multiple photonic processing stages can fit on a single die. Calculations can be scaled over multiple Etiles.
Lower power consumption and thermal emission than electronic equivalents.
Massively flexible. The output of the photonic calculation can be used to construct transforms of different sizes.
Variable precision. Calculation outputs can be used to build transforms to any numerical accuracy.
The silicon photonic infrastructure on Etile is designed to encode digital values into the properties of light.
We control light in silicon photonic waveguides using existing modulation technology.
We can convert complex-valued digital data directly into an optical representation.
Collectively emitting these encoded beams into a free-space environment results in a near-instantaneous transformation of the data through optical interferences.
This calculation is near-instantaneous, consumes no power, and generates negligible heat.
Many of these free-space processing stages can be constructed on a single die.
The optical signals containing the transformed data are then converted back into digital form. This digital data can then be recombined into transform operations of greater size and precision.
Optalysys Enable leverages the power of Etile to provide the massive vector transforms needed for fast and efficient FHE.
In the Enable system, Etile is paired with custom architecture and logic designed around the unique needs of FHE. A dedicated FHE-focused instruction set allows ready low-level interfacing with FHE libraries.
Rounding out the platform is high-density chip-to-chip communication, solving the problem of data transfer that impedes conventional rack-scale FHE solutions.
The result is a single MCM accelerator unit that vastly outperforms a HPC cluster with respect to FHE compute.
The largest operations in FHE can now be performed on-chip, allowing efficient calculation streaming and eliminating interfacing constraints.
Flexible architecture and memory design is intended to support all major FHE schemes.
Parallel Etile processing allows Large Fourier and Number-theoretic transforms in a matter of nanoseconds, vastly outstripping conventional electronics.
A native interface for FHE primitives. Hardware instruction set designed for low-level integration with FHE libraries and APIs.
Achieves FHE performance exceeding that of conventional cluster-scale systems on a single MCM. Designed for hyperscale environments.
Standard PCIe interface for easy integration with supporting hardware.
Our beta program featuring simulators, software and early-access hardware is available now.
