<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>
|
|
<h2 id="roadmap">
|

<a href="#roadmap">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>The initial phase for the long-term roadmap of moving away from the current
|
|
foundation will be to deploy and integrate a hypervisor like Xen to leverage it for
|
|
reinforcing existing security boundaries. Linux would be running inside the virtual
|
|
machines at this point, inside and outside of the sandboxes being reinforced. In the
|
|
longer term, Linux inside the sandboxes can be replaced with a compatibility layer
|
|
like gVisor, which would need to be ported to arm64 and given a new backend alongside
|
|
the existing KVM backend. Over the longer term, i.e. many years from now, Linux can
|
|
fade away completely and so can the usage of virtualization. The anticipation is that
|
|
many other projects are going to be interested in this kind of migration, so it's not
|
|
going to be solely a GrapheneOS project, as demonstrated by the current existence of
|
|
the gVisor project and various other projects working on virtualization deployments
|
|
for mobile. Having a hypervisor with verified boot still intact will also provide a
|
|
way to achieve some of the goals based on extensions to Trusted Execution Environment
|
|
(TEE) functionality even without having GrapheneOS hardware.</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>
