Re: [Teep] Review of draft-ietf-teep-usecase-for-cc-in-network-00

Hi Penglin,

I think there is a need to explain in the document what “network protocol usecase of TEEP” means.

My understanding, from your text below, is that this means that there is a protocol used to provision the confidential computing device, such as the TEEP protocol, rather than having a human configure the device via the command line.

Hi Hannes,

About the title of this document, I used to think different options such as "in remote", "in cloud " or "in network". But in the end I think "in network" is a better or precise term. The reason is as follow:

1，This document is about the network protocol usecase of TEEP, no matter where the confidential computing device is, we should use this network protocol usecase to provision the CC environment. For example, the CC device could be in a public cloud where you want to rent for your personal computing, or in a local area where you could provision by LAN.

2，There are other methods like provision the CC environment by shell or by system administrator directly. I think there scenarios are not in this document's scope. So I prefer to keep "in network" in this document.

Sure, the github link is here https://github.com/ietf-teep/teep-in-cc, you could make comments and create PRs.

Thanks for the very detailed PDF, I think there is no major questions about the comments, I will update the document before 115 meeting.

Hi Penglin,

Thanks for the quick response. Good to hear that you had a broad scope in mind.

In this case I would suggest to remove the “in network” phrase to avoid confusion. In fact, “in network” isn’t mentioned too often in the text of the draft anyway.

Let me know if you have any questions about my handwritten comments in the PDF.

If the document gets added to the working group Github repo, I can also create PRs.

Ciao

Hi Hannes,

Thanks for your review. The scope of this document is not only for edge computing like you mentioned in the pdf. In fact, the scope is for any confidential computing environment which need to be configured by network, like cloud computing, private preserve computing, MEC, etc.

Hi all,

I have reviewed the confidential computing use case document. In the attached PDF there are a few comments.

The document describes a use case of confidential computing for edge devices (although it calls it differently).
That’s indeed one of the confidential computing use cases.

I wonder whether the scope should be extended or is there a specific reason to focus on this use case?

Ciao
Hannes
