Early stage of development
|
|
<a href="#early-stage-of-development">¶</a>
|
|
</h2>
|
|
<p>GrapheneOS is a privacy / security research and engineering project that has been
|
|
under way for over 5 years. It recently became rebranded as GrapheneOS and is taking a
|
|
different direction based on obtaining funding for the research and development work
|
|
as a non-profit open source project rather than being a company. The reborn project is
|
|
still in a very early stage and lots of the past work on privacy and security has not
|
|
yet been restored for the new incarnation of the OS.</p>
|
|
<p>The grapheneos.org site is very new and is currently being put together. It will
|
|
have lots of additional documentation and tutorials in the future along with coverage
|
|
of various software, firmware and hardware privacy/security topics.</p>
|
|
<p>GrapheneOS is being supported with funding and developers from various companies
|
|
and other organizations interested in contributing to this shared base for a feature
|
|
rich private and secure mobile operating system able to run many existing
|
|
applications. It will take more time to organize and deploy these resources in order
|
|
for the project to have a strong development team with proper infrastructure behind
|
|
it.</p>

Roadmap
|
|
<a href="#roadmap">¶</a>
|
|
</h2>
|
|
<p>Details on the roadmap of the project will be posted on the site in the near
|
|
future. In the long term, it aims to move beyond a hardened fork of the Android Open
|
|
Source Project. Achieving the goals requires moving away from relying the Linux kernel
|
|
as the core of the OS and foundation of the security model. It needs to move towards a
|
|
microkernel-based model with a Linux compatibility layer, with many stepping stones
|
|
leading towards that goal including adopting virtualization-based isolation.</p>
|
|
<p>Hardware and firmware security are core parts of the project, but it's currently
|
|
limited to research and submitting suggestions and bug reports upstream. In the long
|
|
term, the project will need to move into the hardware space.</p>
|
|
<h2 id="device-support">
|
|
Device support
|
|
<a href="#device-support">¶</a>
|
|
</h2>
|
|
<p>In the current early stage of the project, GrapheneOS provides production releases
|
|
for the Pixel, Pixel XL, Pixel 2, Pixel 2 XL, Pixel 3 and Pixel 3 XL. It will support
|
|
other devices in the future, but devices are carefully chosen based on their merits
|
|
rather than the project aiming to have broad device support. Broad device support is
|
|
counter to the aims of the project, and the project will eventually be engaging in
|
|
hardware and firmware level improvements rather than only offering suggestions and bug
|
|
reports upstream for those areas. Much of the work on the project involves changes
|
|
that are specific to different devices, and officially supported devices are the ones
|
|
targeted by most of this ongoing work. GrapheneOS also has source level support
|
|
without device-specific hardening for the Android emulator, HiKey, HiKey 960 and also
|
|
generic targets providing basic support for many other devices.</p>
|
|
<p>Devices need to be meet the standards of the project in order to be considered as
|
|
potential targets. In addition to support for installing other operating systems,
|
|
standard hardware-based security features like the hardware-backed keystores, verified
|
|
boot, attestation and various hardware-based exploit mitigations need to be available.
|
|
Devices with support for alternative operating systems as an afterthought will not be
|
|
considered. Devices need to have proper ongoing support for their firmware and
|
|
software specific to the hardware like drivers in order to provide proper full
|
|
security updates too. Devices that are end-of-life and no longer receiving these
|
|
updates will not be supported.</p>
|
|
<p>In order to support a device, the appropriate resources also need to be available
|
|
and dedicated towards it. Releases for each supported device need to be robust and
|
|
stable, with all standard functionality working properly and testing for each of the
|
|
releases.</p>
|
|
<p>Hardware, firmware and software specific to devices like drivers play a huge role
|
|
in the overall security of a device. The goal of the project is not to slightly
|
|
improve some aspects of insecure devices and supporting a broad set of devices would
|
|
be directly counter to the values of the project. A lot of the low-level work also
|
|
ends up being fairly tied to the hardware.</p>
|
|
<p>Some of the GrapheneOS sub-projects support other operating systems on a broader
|
|
range of devices. Device support for Auditor and AttestationServer is documented in
|
|
the <a href="https://attestation.app/about">overview of those projects</a>. The
|
|
<a href="https://github.com/GrapheneOS">hardened_malloc</a> project supports nearly
|
|
any Linux-based environment due to official support for musl, glibc and Bionic along
|
|
with easily added support for other environments. It can easily run on non-Linux-based
|
|
operating systems too, and supporting some like HardenedBSD is planned but depends on
|
|
contributors from those communities.</p>
