Dick, I completely agree. This is what I've been sharing with Kathleen as well. Imagine each instance can configure their policy. They can have their own unique policy for their company, they can configure a deferment to another entity they trust for their industry (horizontal/vertical), or any means they want.

We've implemented a similar pattern with Notary v2, it just happens to be on the client. In this case, we shift the policy to the eNotary within the SCITT instance.

You can imagine scenarios where a more limited set of issuers  might be required, or cases where you really want to be very open.

Steve, et al,

Some industries have a specific set of CA's they have vetted and approved for use, i.e.,  energy industry transactions.

I don't think a single root of trust can be implemented, practically across all industries, if my energy industry experience is any indicator.

Thanks,

It's an interesting example of whether a single root trust store is the best solution.
Just because the browser trusts a root certificate, doesn't mean it's something we individually, or as a company believe is appropriate. We'll just leave the specifics for obvious conclusion.
This just points to the value of having personal, company, industry policy based trust stores

That's correct, Charlie. OATI's root cert is not included in the browser trusted certificate store.

I'm not sure why they chose to do this.

(Side comment: I see that OATI is not a recognized root certificate authority by Mozilla or Apple - didn't check others - so the website is therefore inaccessible without relaxing security.)

Orie,



Here is a high-level overview of the authentication mechanism and tracking used today for OASIS, inter-tie electricity scheduling.



Everything starts with the NAESB registry (EIR); https://www.naesb.org/pdf4/webregistry_mo_registration_quick_ref_guide_v1.0_0417.pdf<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsecure-web.cisco.com%2F1IukwuhEQqregcVfBu_YTf7qloyu0S9CLEMvuw998GuhDfEFcipDth2Xtizyt11QWJE_rg9tKWNdFy9sR6AYzFs5C9RVZkYIdTyO90iI560dk7KjlRPsssiji4ni2uFgQoviKwbEitz9W0A-Jkx8qlZ-bf02dT2GpXl7-qqNgMCReV-n9bPYr7-gF7wRDuDdEpNTctYLkQFh_ODy3F4KcLc2yzJA66rSl-AObqSJo6LSNwG5QHs27-jxMPvsyvzy25FLEf6Q2NCVCA80ajyeRx-DLlAeVOtx8sKKHCAdqS60vvgk6XONNeacK9KVifmF7%2Fhttps%253A%252F%252Fwww.naesb.org%252Fpdf4%252Fwebregistry_mo_registration_quick_ref_guide_v1.0_0417.pdf&data=05%7C01%7CSteve.Lasker%40microsoft.com%7C4f2be070beef426a340e08da7b0365a1%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637957552529574280%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=etxzyiDAecD%2BVw%2F3BmprF1k%2FRPu0HCn14lPaNnbWKrY%3D&reserved=0>



Entities involved in inter-tie electricity transactions must register with NAESB's EIR, see link above.

The registration process requires a party to obtain a NAESB compliant X.509 certificate from an accredited certificate authority (ACA); https://www.naesb.org/pdf4/ac_authorities_2022.pdf<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsecure-web.cisco.com%2F1T_py857nSLdfkwTRZ1F7IUeOLa0Mr0av8bfeuUJwVfOrnlR9B8EzOzxv92Uz4iu2yhDeR4WKL_eKK39aC0HZNHbI0L6S2ynYyf3MIqoWrhcKic931Qc8ha00DiNeKcev3mIQGWSdmm3oQWFZZeYhZ_XBpcojw3HL66SqprENJXYRuXx_69m7-vIbXr6m_muJ25A0-WOODvl0ZvSKLB5bCCNQHy8CETUnFlhi7KK4XlPGw6ngc0NPELIFd66qeSsonDSqajtS6_XsVDeQZ9afWewRkWRR2CS3RPxKELdvgtWbTLdNUMEo_OVauUoZUAaf%2Fhttps%253A%252F%252Fwww.naesb.org%252Fpdf4%252Fac_authorities_2022.pdf&data=05%7C01%7CSteve.Lasker%40microsoft.com%7C4f2be070beef426a340e08da7b0365a1%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637957552529574280%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=v2M6eAhls0eu6%2Bp4Nn3XKmU3GC0nBWos96KrgtE20Hc%3D&reserved=0>

I am interested in applying Verifiable Credentials to energy use cases, even if we don't have customers in that sector today.

There are also aspects of Verifiable Credentials that I believe are relevant to the structure of endorsements / receipts:

The concept of "evidence":

As one example.

I am hopeful that the next version of the Verifiable Credentials specification can point more directly to IETF RFCs to make its arguments,
even if the json data model can't be updated to support CBOR / COSE as a first class citizen this round.
Perhaps the next charter for that WG might support this better, if we pave the way with examples.

OS

I agree. This paper by Orie, Michael, Brian and Mahmoud is very useful as guide for terminology and semantics.



I can provide the authors with a description of how we track electricity transactions for inter-tie scheduling, called OASIS a NAESB standard, if interested.

As it says in the readme, this is just a toy example I made up to experiment with.

The nice thing about endorsing W3C Verifiable Credentials is that they are already an abstraction that applies to "non software supply chain" use cases...

For example, we model cyber physical supply chain flows using them:

https://w3id.org/eability<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsecure-web.cisco.com%2F12vv3ms4fQAlyFEE4k1zPXuwNVQhbw5JZJG1gBL6pcqttkVpsiI3zrO00D8muCuDxuryJz9JNlTjNav5jhFZwmrDOzf2g002uvnOa4j5zplIUKqg9fIr9y-JZ4w5q4mXJXza6z62EHNy6BzBsjPIluYavv0fR109auX6z1titrQhnW1fmk_usfbPqwJgY780ZABU5QTV12sZSiHaInC4MzZokObYCrnulteZlYaIml9emeQtOkK5mYExh0HK13aas-6VpgxE3PbRyBO3h9W_wUt3BpoaWT0QrjMaAM3NSTsiDsayitR5Pm48JR4E_wr_U%2Fhttps%253A%252F%252Fw3id.org%252Feability&data=05%7C01%7CSteve.Lasker%40microsoft.com%7C4f2be070beef426a340e08da7b0365a1%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637957552529730969%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=bahzXBxWNyOQksYOgzpnRTkOC8FMFuSyeNOTiU6Jtfg%3D&reserved=0>

There are a number of organizations looking at oil and gas, steel, ecommerce, and agriculture supply chains.

Often they will share some common trade documents such as Bills of Lading or Commercial Invoices.

These are examples of "SCITT Artifact Types" which you might expect to see across various distinct supply chain use cases.

However, as is the case with Oil and Gas needing to account for fluid dynamics, and software needing to account for compilers, build servers and various source files, there are cases where you may need to model components of a supply chain with Verifiable Credentials that are highly specific to the use case.

If you can tolerate modeling in RDF, W3C Verifiable Credentials come with a built in abstract data model that integrates well with existing industry ontologies such as:

My main complaint against W3C Verifiable Credentials is the limitation to JSON representations, if we could represent RDF in CBOR, we would have the best of both worlds with the main remaining disadvantage being the namespace overhead inherent in RDF.

If you drop that, you will likely need some registry or algorithm process for handling collisions and interoperability, but there are various solutions to those problems.

If you feel I butchered any of the concepts or terminology, feel free to yell at me here or on github issues, as I said, I made this today, it's not reflective of actual SCITT architecture, it was just to explore the space.

OS
