Build, deploy, generate keys, and query an encrypted pipeline

Lattica Studio is a workspace for the lifecycle of a homomorphic pipeline. You build it from Lattica's operators and deploy it to the Lattica Platform, where you can manage resources and user access. Encrypted queries are processed without decryption, and the result remains encrypted until it is returned to the user.

The lifecycle

Four stages, in order. To get started, you need a Lattica license and an installation of Lattica Studio. Open any stage to see its steps.

STAGE 1 · YOUR WORK

Build

assemble a pipeline from HomOps3 steps

on your machine · the part you write

1

Compose with HomOps

operators shaped like standard ML ops, with extra parameters for FHE

2

Set the structure

arrange your HomOps into the computation graph

3

Define parameters

shapes, weights, and encryption params

STAGE 2

Deploy

deploy_pipeline()3 steps

studio.deploy_pipeline()

On upload or compile error, fix the pipeline and deploy again from Build.

1

Register or reuse

create a model, or redeploy into the same name

2

Upload

pipeline + params

3

Compile

the backend turns it into an FHE circuit

STAGE 3

Key generation

create token, generate keys2 steps

tokens.create + keys.ensure

1

Create access token

studio.tokens.create, saved locally for this model name

2

Register keys

secret key stays; evaluation key uploads and registers; no worker needed

STAGE 4

Query

run encrypted queries against your pipeline4 steps

query loop

1

Start worker

credits begin for the query session

2

Load existing key

keys.ensure() reuses local artifacts; worker loads registered EVK

3

query.encrypted()

repeat as many times as you need

×N

4

Stop worker

credits stop

Click a stage to collapse or open it. Build and key generation run on your machine; Deploy registers and compiles on the platform, and Query uses a worker.

Where it runsYour machineLattica Studio + platformToken and keysWorker

Studio and Query Client can be together, but they do not have to be.

For development and testing, the Query Client can run in the same environment as Lattica Studio. In production, it can run in a separate environment, allowing encrypted queries to be sent from wherever the end user is running their application.

Before starting a worker, make sure your account has enough credits.

Where to go next

Read the concepts first if homomorphic pipelines are new to you. Otherwise, start at the stage you care about.

Start here

Concepts →

The mental model: pipelines, operators, keys, and tokens, in plain terms.

Stage 1 · the main work

Build the Pipeline →

Arrange HomOps into your pipeline, then set shapes, weights, and encryption parameters.

Stages 2 and 3

Deploy the Pipeline →

Upload and compile, then create a token and generate keys.

Stage 4

Run Queries →

Start a worker, load keys, send encrypted queries, read decrypted results, stop the worker.
