<p class="MsoNormal"><span lang="EN-US">Hi, <o:p></o:p></span></p>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">I agree that the use case of a trusted IaaS provider (with possibly compromised nodes) is a valid one and should have support in the openstack codebase, although it seems rather dicey to trust the IaaS provider which
does not trust it's own hosts.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">And your understanding is correct, the idea is to add a 3rd party 'CA' with the aim to assess the integrity of the hosts based on the data produced by the TPM.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">What I am advocating here is the scenario where the IaaS can not be trusted. <o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">In this case the CA would only gain information about the software stack of the IaaS provider's hosts, necessary to perform the attestation. However, imo an IaaS provider that claims to offer trusted hosts but hesitates
to reveal the software stack of it's hosts to an external auditor (CA in this case) would have issues with credibility.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>

<p class="MsoNormal"><span lang="EN-US">Wrt complexity, this would require:<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">* sending the attestation information externally to the 'CA' and taking a launch/not launch decision based on the result of the attestation. Even if the untrusted IaaS launches the VM, the client can easily detect the
fraud.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">* on the compute host, decrypting the nonce provided by the client (and _sealed_ by the CA to the trusted configuration of the host). That will add up to the codebase but is rather trivial (involves mostly interacting
with the TPM).<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">Now, there are some design choices to be made, e.g. whether the host communicates its attestation credentials directly to the CA in an https session or the scheduler does that. However, it does not change the important
point that the client can verify that the VM was started on a trusted host, without having to rely on the IaaS provider.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span lang="EN-US">A common topic to both models (trusted or untrusted IaaS provider) is the question of "security profiles" for the hosts -- are you considering binary values (trusted/untrusted) or some finer-grained scale?<o:p></o:p></span></p>
