|
|
<p>GrapheneOS is an open source privacy and security focused mobile OS with Android
|
|
app compatibility. It's focused on the research and development of privacy and
|
|
security technology including substantial improvements to sandboxing, exploit
|
|
mitigations and the permission model. GrapheneOS also develops various apps and
|
|
services with a focus on privacy and security.</p>
|
|
<p>GrapheneOS is a collaborative open source project, not a company. It's used and
|
|
supported by a variety of companies and other organizations. It won't be closely tied
|
|
to any company in particular. There will eventually be a non-profit GrapheneOS
|
|
foundation, but for now the developers represent the project.</p>
|
|
<p>GrapheneOS has made substantial contributions to the privacy and security of the
|
|
Android Open Source Project, along with contributions to the Linux kernel, LLVM,
|
|
OpenBSD and other projects.</p>
|
|
<p>GrapheneOS was founded by Daniel Micay in late 2014. It started as a solo project
|
|
was subsequently sponsored by a company that is no longer associated with it. The
|
|
copyright for GrapheneOS code is entirely owned by the GrapheneOS developers and is
|
|
made available under OSI approved Open Source licenses. All of the code written by
|
|
people under contract with the former sponsor was removed from the project due to
|
|
becoming obsolete, long before it was known as GrapheneOS. The code that remains from
|
|
the previous era is entirely owned by Daniel Micay, was never written under any
|
|
contracts or employment agreements, was never assigned to any company or organization
|
|
and was the continuation of the original independent open source project. The former
|
|
sponsor attempted to take over the project through coercion, but they were rebuked,
|
|
and since then they've taken to fraudulently claiming ownership and authorship of our
|
|
work which has no basis in fact. The former sponsor has engaged in a campaign of
|
|
misinformation and harassment of contributors to the project. Be aware that they are
|
|
actively trying to sabotage it through any means necessary to support their failing
|
|
business. This paragraph was reluctantly included here despite wanting to move
|
|
forwards and will be expanded if necessary.</p>

of the OS and various standalone sub-projects including the cutting edge

|
<p>The official GrapheneOS releases are supported by the
|
|
<a href="https://github.com/GrapheneOS/Auditor/releases">Auditor app</a> and
|
|
<a href="https://attestation.app/">attestation service</a> for hardware-based
|
|
attestation. For more details, see the <a

support for your own builds.</p>

<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>
