Welcome to SCONE Platform

Fork Support (2019-07-17)

SCONE supports execution of unmodified programs inside of SGX enclaves by recompilation. For Alpine Linux, a recompilation is recommended but not required. We just added fork support, i.e., a process running inside an enclave can fork child processes. This permits SCONE to support applications like sklearn.

Public CAS for development (2019-06-22)

Added new documentation for our configuration and attestation service (CAS): now with public CAS for testing and development.

Public Blender Image (2019-05-02)

We demonstrate on how SCONE supports always encrypted secure remote execution with a public image: We provide this functionality with the help of blender (ray tracer) in our secure remote execution tutorial. We show how to encrypt application code and user input in our advanced blender use case.

Full Tensorflow Support (2019-04-08)

SCONE now supports full Tensorflow in addition to TensorFlow Lite inside Intel SGX. Read our overview to learn more.

Executive Summary

The SCONE platform facilitates always encrypted execution: one can run services and applications such that neither the data nor the code is ever accessible in clear text - not even for root users. Only the application code itself can access the unencrypted data and code. SCONE simplifies the task of encrypting the input, executing the service/application in encrypted memory on an untrusted host, transparently encrypting the output and shipping the output back to the client.

SCONE Workflow

SCONE helps to ensure that data, communications, code and the main memory is always encrypted. To do so, SCONE needs to verify (i.e., attest) that the expected application code is running in a trusted execution environment on a potentially untrusted host. Read our secure remote execution tutorial to see how to perform an encrypted remote execution in a single step. In this way, one can even execute encrypted code. We show how to execute encrypted Python scripts in the context of blender.

SCONE Workflow

SCONE can help you to encrypt your input and output data on your local computer. The keys are managed with the help of SCONE CAS (Configuration and Attestation Service). SCONE CAS itself runs, of course, inside an enclave. It can either run on the client side or on a remote host. It can even be operated by an untrusted entity and still be trusted by CAS clients.

SCONE CAS

SCONE supports multiple stakeholders that do not necessarily trust each other. SCONE supports users, service providers, application providers, data providers and infrastructure providers. They can all work together and SCONE can ensuring that each party can protect its own intellectual property. Some of the services, like SCONE CAS, can be actually operated by not necessarily trusted stakeholders since clients can verify that the services are in the correct state.
